AB  - Ostrinia nubilalis Hbn. je štetočina kukuruza koja u pojedinim godišnjim dobima može naneti
veliku štetu biljkama. Cilj ovog rada je proučavanje otpornosti odnosno podložnosti hibrida
napadu kukuruznog plamenca i efekata različitih doza insekticida i vremena primene u zaštiti od
ove štetočine na biljkama kukuruza, ali prvenstveno uticaj hibrida na intenzitet napada. Šest
hibrida kukuruza različitih grupa zrenja (ZP 427, ZP 434, ZP 555, ZP 600, ZP 606 i ZP 666)
korišćeno je za proučavanje dejstva napada Ostrinia nubilalis Hbn., na kontrolnu varijantu T1
bez primene insekticida i na varijantu tretiranu sa dva insekticida Fobos EC (bifentrin - 200 ml
ha-1) i kombinacijom Match 050 EC i Nurelle D (lufenuron 50 g l-1 i hlorpirifos 500 g l-1 +
cipermetrin 50 g l-1), 0.75 l ha-1) u dva termina (u prvoj generaciji za vreme leta insekata T2 i
T3 i u drugoj generaciji za vreme leta insekata T4 i T5) u tri ponavljanja. Rezultati su pokazali
najveći intenzitet Ostrinia nubilalis Hbn. napad i stepen oštećenja na kontrolnoj varijanti i
značajne razlike između tretmana za ispitivane parametre. Posmatrajući sve hibride i tretmane,
nije utvrđena statistička značajnost između šest ispitivanih hibrida kukuruza različitih grupa
zrelosti. U kontrolnoj varijanti najveći napad (oštećenje) je bio na biljkama kod hibrida ZP 666
(94,28%) i ZP 606 (93,90%), a među varijantama primenjenih insekticida najveća šteta je
konstatovana u tretmanu T5 sa primenjena kombinacija Match + Nurelle u hibridu ZP 555 i
iznosila je 92,02%. Na tretmanu T1-kontrolna varijanta bez insekticida, najmanji napad sa
Ostrinia nubilalis Hbn. je konstatovan kod hibrida ZP 434 (od 88,76%), a među varijantama
primenjenih insekticida najmanji napad je konstatovan kod varijante T2 sa primenjenim Fobos
kod prve generacije insekata u hibridu ZP 434 i iznosio je 77,12%. Napad Ostrinia nubilalis
Hbn. i varijacija prosečne mase klipa kukuruza varirala je u zavisnosti od hibrida kukuruza i
vremena primene insekticida.
AB  - Ostrinia nubilalis Hbn. is a corn pest that can do great damage to plants in some seasons.
The aim of this paper is to study the resistance / susceptibility of hybrids to the attack of
European corn borer and the effects of different doses of insecticides and time of
application in protection against pests on maize plants, but primarily the influence of
hybrids on attack intensity. The six maize hybrids of different maturation groups (ZP 427,
ZP 434, ZP 555, ZP 600, ZP 606 and ZP 666) used for study effect of attack of Ostrinia
nubillalis Hbn., on control variant T1 without application of insecticide and on variant
treated with two insecticides Fobos EC (bifentrin - 200 ml ha-1
) and combination of Match
050 EC and Nurelle D (lufenuron 50 g l
-1
and hlorpirifos 500 g l
-1 + cipermetrin 50 g l
-1
),
0.75 l ha-1
) in two terms (in the first generation of insect flying T2 and T3 and in the
second generation of insect flying T4 and T5) in three replication. The results showed the
highest intensity of Ostrinia nubilalis Hbn. attack and degree of damages on control
variant and significant differences between treatments for investigated parameters.
Observing all hybrids and treatments, there was no statistical significance between the six
examined maize hybrids of different maturity groups. In the control variant, the greatest
attack (damage) was in plants, namely in the hybrid ZP 666 (94.28%) and ZP 606 (93.90%) and among the variants of applied insecticides, the greatest damage was found
in the treatment T5 with the applied combination of Match + Nurelle in hybrid ZP 555
and was 92.02%. On treatment T1-control variant without insecticides, the smallest attack
with Ostrinia nubilalis Hbn. was found in the hybrid ZP 434 (from 88.76%) and among
the variants of applied insecticides, the smallest attack was found on variant T2 with
applied Phobos in the first generation of insect in hybrid ZP 434 and amounted to
77.12%. The attack of Ostrinia nubilalis Hbn. and variation of average mass of maize cob
varied in dependence of maze of hybrids and variant of insecticides application.

AB  - During last years, the total losses from European corn borer (Ostrinia nubilalis Hbn.) can reach
a high threshold of harmfulness although the different agro-technical measures that are being
implemented. According to the sensitivity of hybrids, the damage may vary from only a few
percent in tolerant hybrids, up to 30-40% on moderately intolerant hybrids. The aim of this
study was to evaluate the variability and bioresponsiveness of four maize genotypes (ZP 427,
ZP 434, ZP 600 and ZP 666) to applied insecticides and bioinsecticides and the
interdependence of population dynamics. The research has been conducted in 2016 and 2018
in accordance with the EPPO method in field conditions in maize crops. Out of a total of 11.023
attacks in both years of research, in 2016. the largest number of plants (4.841) were with a
broken stalk above the ear and at the height of the ear and belonged to categories C3 to C8. In
2018. 3.672 plants were dominated by leaf damage and perforation in the stalk type H2.
Analyzing the effectiveness of the tested insecticides and bioinsecticides by application times,
an uniformity in the number of plants with recorded symptoms of damage was observed. Thus,
foliar treatment with chlorantraniliprole insecticide proved to be the most effective with the
least number of attacked plants with a high degree of damage. In contrast, bioinsecticide
treatment of plants, in addition to a large number of infested plants, was dominated by high
categories of damage that deviated from all other treatments as well as from the control. Within
the definition of the degree of tolerance of maize hybrids, the influence of treatment on changes
in secondary metabolites (phytins) in seeds was observed. It was noticed that there is a trend
of positive correlation of the amount of phytin in the seed (mg/g) with the attack of moths of
the first generation and the number of dissected larvae, as well as a trend of negative correlation
with the percentage of attacks of moths of the second generation. Correlation coefficients are
expressed: in the genotype ZP-600, while in the genotype ZP-666 the correlation is the lowest,
ie. irrelevant. The obtained results may be of great importance in future work aimed at the
selection of tolerant genotypes to attack corn flame, taking into account the role of phytin, as
an antioxidant and phosphorus depot in maize grain.

AB  - Many insect species overcome unfavourable environmental conditions by entering 
diapause, a type of hypometabolic resting state which features accumulation of energy 
reserves, lowered oxidative metabolism rates, synthesis of protective metabolites and 
expression of specific genes. In order to better understand the changes occuring at the 
transcriptional level during diapause of the economically important European corn borer 
Ostrinia nubilalis (Hbn.), the expression of genes encoding selected metabolic enzymes 
was measured in this study. The selected enzymes are markers of aerobic (citrate synthase, 
aspartate aminotransferase, alanine aminotransferase) and anaerobic metabolism (lactate 
dehydrogenase). Total RNA was isolated from whole-body non-diapausing (ND) and 
diapausing (D) 5th instar larvae acclimated to different temperatures (15°C, 5°C, –3°C, –
16°C) due to a close link between diapause and cold hardiness in this species. QPCR was 
performed and relative gene expression was determined using rps3 as the reference gene 
and the ND group as control. Relative expression of cs gene did not differ between groups, 
suggesting that this enzyme is regulated posttranslationally. Relative expressions of ast and 
alt genes were significantly higher in the ND group compared to diapausing larvae, while 
the expression of ldh was higher in the diapausing groups. A temperature effect on relative 
gene expression of cs, ldh and alt was determined. Higher cs expression was recorded in 
diapausing larvae acclimated to 5°C compared to D(15°C), probably compensating for 
lowered CS enzyme activity. Cold acclimation leads to higher expression of ldh in 
diapausing larvae, especially in D(–3°C) group, as expected. Lastly, acclimating 
diapausing larvae to 5°C and –3°C resulted in higher expression of alt in these groups 
compared to D(15°C) larvae, leading to an increase of the cryoprotective alanine synthesis.

AB  - The European corn borer Ostrinia nubilalis is a pest species, whose fifth instar larvae gradually develop cold hardiness during diapause. The physiological changes underlying diapause progression and cold hardiness development are still insufficiently understood in insects. Here, we follow a complex of changes related to energy metabolism during cold acclimation (5°C) of diapausing larvae and compare this to warm-acclimated (22°C) and non-diapause controls. Capillary electrophoresis of nucleotides and coenzymes has shown that in gradually cold-acclimated groups concentrations of ATP/ADP and, consequently, energy charge slowly decrease during diapause, while the concentration of AMP increases, especially in the first months of diapause. Also, the activity of cytochrome c oxidase (COX), as well as the concentrations of NAD+ and GMP, decline in cold-acclimated groups, until the latter part of diapause, when they recover. Relative expression of NADH dehydrogenase (nd1), coenzyme Q-cytochrome c reductase (uqcr), COX, ATP synthase (atp), ADP/ATP translocase (ant), and prohibitin 2 (phb2) is supressed in cold-acclimated larvae during the first months of diapause and gradually increases toward the termination of diapause. Contrary to this, NADP+ and UMP levels significantly increased in the first few months of diapause, after gradual cold acclimation, which is in connection with the biosynthesis of cryoprotective molecules, as well as regeneration of small antioxidants. Our findings evidence the existence of a cold-induced energy-saving program that facilitates long-term maintenance of larval diapause, as well as gradual development of cold hardiness. In contrast, warm acclimation induced faster depletion of ATP, ADP, UMP, NAD+, and NADP+, as well as higher activity of COX and generally higher expression of all energy-related genes in comparison to cold-acclimated larvae. Moreover, such unusually high metabolic activity, driven by high temperatures, lead to premature mortality in the warm-acclimated group after 2 months of diapause. Thus, our findings strongly support the importance of low temperature exposure in early diapause for gradual cold hardiness acquisition, successful maintenance of the resting state and return to active development. Moreover, they demonstrate potentially adverse effects of global climate changes and subsequent increase in winter temperatures on cold-adapted terrestrial organisms in temperate and subpolar regions.

abstract = "The European corn borer Ostrinia nubilalis is a pest species, whose fifth instar larvae gradually develop cold hardiness during diapause. The physiological changes underlying diapause progression and cold hardiness development are still insufficiently understood in insects.

AB  - Soybean is one of the most economically important grain crops. As the
source of plant protein and vegetable oil, it is widely used as food and
industrial crop. Quality of soybean oil is determined by fatty acid (FA)
composition. Biochemical variation of different varieties significantly
facilitates genetic screening of kernel traits and grain quality attributes, thus
leading to one of the most important breeding strategies - improvement of
the grain composition. The main objective of this work was to evaluate
whole kernel biochemical composition of eight soybean varieties and eight
lines from different breeding programs. Phytochemical characterization was
conducted for total protein and oil content, as well as for fatty acids content
(e.g. palmitic, stearic, oleic, linoleic and linolenic acid). According to
Kjedahl method, total protein content ranged from 37.01% to 39.91%. The
obtained results showed that the lowest and the highest values for oil content
were 19.00% and 21.34%, respectively. Gas Chromatography/Flame
Ionization Detector (GC-FID) was used for FA quantification and
determination. The most abundant FA was linoleic acid with a range from
47.45 to 55.7 g/100g, followed by oleic acid with detected rage from 22.59
to 29.07 g/100g of total FA content. Palmitic, linolenic and stearic FA
showed a significantly lower level varied from 9.57 to 11.51 g/100g, 5.42 to
7.18 g/100g and 3.73 to 5.86 g/100g, respectively. This variability observed
in kernel quality among soybean genotypes can provide valuable information
for future breeding.

AB  - The European corn borer, Ostrinia nubilalis Hbn., is a pest Lepidopteran species whose larvae overwinter by entering diapause, gradually becoming cold-hardy. To investigate metabolic changes during cold hardening, activities of four metabolic enzymes – citrate synthase (CS), lactate dehydrogenase (LDH), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured in whole-body homogenates of pupae, non-diapausing and diapausing larvae acclimated to 5 °C, −3 °C and −16 °C. The highest CS activity was detected in non-diapausing larvae, reflecting active development, while the highest in vitro LDH activity was recorded in diapausing larvae at temperatures close to 0 °C, evidencing a metabolic switch towards anaerobic metabolism. However, in-gel LDH activity showed that production of pyruvate from lactate is triggered by sub-zero temperatures. The activities of both aminotransferases were highest in non-diapausing larvae. Our findings suggest that during diapause and cold hardening the aminotransferases catalyse production of L-alanine, an important cryoprotectant, and L-aspartate, which is closely tied to both transamination reactions and Krebs cycle. The results of this study indicate that, during diapause, the activity of metabolic enzymes is synchronized with exogenous factors, such as temperatures close to 0 °C. These findings support the notion that diapause is metabolically plastic and vibrant, rather than simply a passive, resting state.

AB  - The   objective   of   the   paper   was   to   determine   the   effect   of   insecticides   on   the development  of  the  European  corn  borer  (Ostinia  nubilalisHbn)  and  the  effect  of damage  in  six  maize  hybrids  of  different  maturity  groups.  The  research  involved  the following  hybrids:  ZP  427,  ZP  434,  ZP  555,  ZP  600,  ZP 606  and  ZP  666.  In  the  field trial,  insecticides  were  applied  in  two  terms,  during  the  flight  of O.  nubilalisfirst generation and during theflight ofsecondO. nubilalisgeneration. We  used Fobos EC insecticide and a combination of Match 050 EC + Nurelle D insecticides, whose active substances are different. The active substance in Fobos EC insecticide is bifenthrin 100 g l-1,  in  Match  050  EC  lufenuron  50  g l-1 and,  in  Nurelle  D  insecticide,  the  active ingredient  is  a  combination  of  chlorpyrifos  500  g l-1and  cypermethrin  50  g l-1.  The damageinflicted  on  plants  was  assessed  in  July  and  September.  Fobos  insecticide  had the  best  plant  protection  effect,  after  its  use,  the  arithmetic  mean  of  the  total  attack percentage of all hybrids was approximately 81.62% while in the control group, it  was approximately 91.72%.
AB  - Cilj  rada  je  bio  da  se  utvrdi  efekat  insekticida  na  razvoj  kukuruznog  moljca  (Ostinia nubilalisHbn) i efekat oštećenja u šest hibrida kukuruza razliĉitih grupa zrenja. Istraţivanje je obuhvatilo  sledeće  hibride  ZP  427,  ZP  434,  ZP  555,  ZP  600,  ZP  606  i  ZP  666.  U  ogledu, insekticidi su primenjeni u dva termina i to: u vreme leta prve generacije O. nubilalisi posle toga u vreme letenja druge  generacije  O. nubilalis.  U istraţivanjima su korišćeni insekticidi: Fobos EC insekticid i kombinacija insekticida Match 050 EC + Nurelle D ĉije su aktivne supstance razliĉite. Aktivna supstanca kod insekticida FobosEC je bifentrin 100 g l-1, kod Match 050 EC je lufenuron 50 g l-1, a kod  insekticida Nurelle D  aktivna supstanca je kombinacija  hlorpirifos 500 g l-1i  cipermetrin  50  g l-1. Ocena oštećenja na biljkama je vršena u julu i septembru u godini eksperimenta. Insekticid  Fobos je imao nabolji efekat zaštite biljaka. Ustanovljen  je najbolji efekat Fobosa u zaštiti biljaka, posle ĉije primene je nadjeno oštećenje kod 81.62% proseĉno za sve hibride, što je znaĉajno razliĉito od napada  kukuruznog plamenca na kontrolnoj  varijanti, bez upotrebe insekticida, na kojoj je nadjeno 91,72% napadnutih biljaka proseĉno za sve hibride. U analizi tretmana insekticidima, najniţi ukupni napad je nadjen kod ZP 434 hibrida i to 77,12% napadnutih biljaka posle tretmana Fobos (I-1); dok je najveći ukupni napad (88.55%) nadjen kod  ZP  555  hibrid  posle  tretmana  Match  +  Nurelle  (II-1).  U  proseku  primena  insekticida  u  vreme prve  generacije  napada  je  bila  efikasnija  nego  primena  insekticida  u  vreme  razvijene  druge generacije   kukuruznog   plamenca   (Ostrinia   nubilalis).   Intenzitet   napada   prve   generacije kukuruznog  plamenca,  je  bio  najniţi  kod  ZP  666  hibrida  (13,07%)  u  varijanti  primenjenog insekticida Fobos (I-1), dok je najviši u ZP 427 hibrida -35.54%. Napad druge generacije je bio najmanjeg intenziteta kod ZP 434 hibrida (43,24%), a najviša u ZP 666 hibrida (68,62%) posle tretmana sa insekticidom Fobos (I-1). Proseĉno za sve hibride najveći intenzitet napada u vreme  prve, kao i u vreme druge  generacije kukuruznog plamenca je ustanovljen u kontrolnoj varijanti (bez tretmana insekticidom) koji je bio veći u odnosu intenzitet napada na tretiranim varijantama sa  insekticidom.  Na  kontrolnoj  varijanti,  intenzitet  napada  ocenjen  u  vreme  prve  generacije O. nubilalisje vrarirao u rasponu od najvećeg kod  ZP 606 hibrida (69.29%), do najmanjeg kod ZP 434 hibrida (64.36% ), dok je u vreme druge generacije intenzitet  napada  varirao u rasponu od najvećeg kod ZP 666 hibrida (26,93%) do najmanjeg kod kod ZP 555 hibrida (23.9%).

Intenzitet   napada   prve   generacije kukuruznog  plamenca,  je  bio  najniţi  kod  ZP  666  hibrida  (13,07%)  u  varijanti  primenjenog insekticida Fobos (I-1), dok je najviši u ZP 427 hibrida -35.54%. Napad druge generacije je bio najmanjeg intenziteta kod ZP 434 hibrida (43,24%), a najviša u ZP 666 hibrida (68,62%) posle tretmana sa insekticidom Fobos (I-1). Proseĉno za sve hibride najveći intenzitet napada u vreme  prve, kao i u vreme druge  generacije kukuruznog plamenca je ustanovljen u kontrolnoj varijanti (bez tretmana insekticidom) koji je bio veći u odnosu intenzitet napada na tretiranim varijantama sa  insekticidom.  Na  kontrolnoj  varijanti,  intenzitet  napada  ocenjen  u  vreme  prve  generacije O. nubilalisje vrarirao u rasponu od najvećeg kod  ZP 606 hibrida (69.29%), do najmanjeg kod ZP 434 hibrida (64.36% ), dok je u vreme druge generacije intenzitet  napada  varirao u rasponu od najvećeg kod ZP 666 hibrida (26,93%) do najmanjeg kod kod ZP 555 hibrida (23.9%).",

AB  - Sweet corn is considered as tasty and quality food. Its kernels contain sugars that are in good balance  with  amino  acids,  minerals  and  vitamin  B.  It  is  used  as  fresh  product  right  after  the  harvest,  but  also  for  further  industrial  processing,  freezing  and  canning.  In  breeding  of  sweet  corn,  equal  attention  is  paid  to  the  production  of  high  and  stable  yielding  hybrids,  and  to  the  enhancement of technological and sensory properties of the ear and kernel. The aim of this re-search was to establish agronomic and sensory properties of 12 sweet corn hybrids, 3 commercial and 9 experimental. The trial was set up according to the RCBD on two locations and in three replicates. The evaluation of agronomic parameters encompassed: fresh ear yield without husk, ear  length,  number  of  kernel  rows  and  shelling  percentage.  Also,  sensory  characteristics  were  analyzed:  appearance,  color,  smell,  sweetness,  juiciness,  crispiness,  pericarp  hardness.  Sensory  characteristics were evaluated by voluntary panelists and scaled with 1 – 9 point hedonic scale. Fresh  ear  yield  significantly  varied  over  locations  and  hybrids.  The  highest  fresh  ear  yield  had  experimental hybrid ZP 481/1su – 13.33 t ha-1, while the lowest was 7.14 t ha-1 (ZP504su). The difference between sensory characteristics among hybrids was also noticed, although all hybrids had satisfactory sensory characteristics with the average sensory marks above 7.30/9.00. The best sweet corn hybrid according to sensory characteristics was ZP 483/1su (8.29), while the highest yielding one ZP 481/1su had an average sensory mark 7.70.

Koristi  se  u  svežem  stanju  odmah  nakon  berbe,  ali  takođe  i  za  industrijsku  preradu  i  zamrzavanje  zrna.  U  procesu  ople-menjivanja  kukuruza  šećerca,  podjednaka  pažnja  posvećuje  se  stvaranju  hibrida  visokog  i  sta-bilnog  prinosa,  kao  i  poboljšanju  tehnoloških  i  senzornih  karakteristika  klipa  i  zrna.  Cilj  ovog  istraživanja bio je da se utvrde agronomske i senzorne karakteristike 12 hibrida kukuruza šećerca, od kojih su tri hibrida bila komercijalna, a 9 eksperimentalnih. Ogled je bio postavljen po prin-cipu RCBD, na dve lokacije i u tri ponavljanja. Analiza agronomskih karakteristika obuhvatila je: prinos svežeg klipa bez komušine, dužinu klipa, broj redova zrna i randman zrna. Od senzornih karakteristika analizirane su sledeće: izgled klipa, boja, miris, slatkoća, sočnost, hrskavost i tvr-doća  perikarpa.  Senzorne  karakteristike  procenjivalo  je  15  dobrovoljaca,  koristeći  skalu  1  –  9.  Prinos svežeg klipa značajno je varirao u odnosu na lokacije i hibride. Najviši prinos postigao je eksperimentalni hibrid ZP 481/1su – 13,33 t ha-1, dok je najniži prinos bio kod hibrida ZP504su (7,14 t ha-1). Razlike u pogledu senzornih karakteristika između posmatranih hibrida takođe su primećene, ali svi hibridi su uglavnom imali zadovoljavajuće senzorne ocene sa srednjom vred-nošću  preko  7,30/9,00.  Najbolji  hibrid  kukuruza  šećerca  prema  senzornim  ocenama  bio  je  ZP  483/1su (8.29/9,00), dok je najprinosniji hibrid ZP 481/1su imao nisku senzornu ocenu od 7,70.

AB  - Soybean (Glycine max (L.) Merr.) is one of the oldest crop in the world, with a history of growing over 4000 years. At the same time it is the most important legume in the global world production. Simple Sequence Repeat (SSR) markers are widely used for estimation of genetic diversity within different species, due to their reproducibility, co-dominant and multi-allelic nature. Molecular characterization among soybean genotypes was done with 36 SSR markers, with at least one primer from each linkage group, to determine the genetic diversity. Twenty soybean accessions and varieties obtained from Maize Reasearch Institute „Zemun Polje“ were analyzed. A total number of detected alleles was 116 and number of alleles varied between two to six, with an average of 3.22 alleles per marker. Thirteen unique alleles were obtained from eleven SSR loci in nine genotypes. Molecular analysis revealed a high polymorphism of SSR loci. Pairwise coefficients of genetic similarity calculated by Dice ranged from 0.14 to 0.74. Genetic similarity matrix was used to construct dendrogram by UPGMA (Unweighted Pair Group Method with Arithmetic Mean) method in NTSYSpc2 program package. This clustering method distinguished 20 soybean genotypes in two subclusters and one branch.

AB  - Western corn rootworm (WCR) (Diabrotica virgifera virgifera LeConte) is one of the most important and potentially most dangerous pests of maize. Since its occurrence in Serbia in 1992, it has been present in almost all areas under maize cultivation. Alongside with all preventive measures, first of all, the crop rotation, which is considered the most economic one, a great attention has been paid to the forecast of the pest occurrence based on the flight dynamics and the population level. The flight dynamics, sex dominance, variations in the population level depending on the trap types and climate factors were observed on two locations: Crepaja in three-year continuous cropping (2005-2007) and in the experimental field of the Maize Research Institute, Zemun Polje in the duration of five years (2005-2009). According to the flight dynamics of WCR adults, the highest population level of this pest was observed in 2005, while the comparison of the number of adults over locations showed greater abundance of the pest in Crepaja than in Zemun Polje, which was attributed to extreme favourability of agro-ecological conditions on this location for the WCR development. The 2008-2009 period was characterised by the reduced number of WCR, which coincided with the extremely arid conditions that do not favour the development of this pest.
AB  - Pojava Diabrotica virgifera virgifera LeConte na teritoriji Srbije od 1992. godine, rezultirala je masovnim razmnožavanjem i brzim teritorijalnim širenjem. Brojnost populacije je povećavana iz godine u godinu, naročito u područjima gde je kukuruz gajen u monokulturi i dostizala je kritične vrednosti pri kojima nastaju ekonomske štete. Plodored i variranje klimatskih faktora značajno su uticali na pad brojnosti i ostale parametre dinamike populacije. Cilj istraživanja je bio da se formuliše strategija kojom bi se ostvarila ekološki racionalna kontrola kukuruzne zlatice, zasnovana na prognozi pojave i praćenju brojnosti imaga oba pola, u korelaciji sa klimatskim uslovima i sistemom gajenja kukuruza. Dinamika leta kukuruzne zlatice praćena je vizuelnom metodom, primenom feromonskih Csalomon, žutih (Pherocon AM®) i zelenih lepljivih klopki tipa Multigard, u periodu od početka jula do kraja septembra. Klopke su postavljane početkom jula, na biljke kukuruza iznad klipa, menjane su svake dve nedelje, a pregled klopki vršen je svaki treći dan. Dobijeni rezultati su ukazali na dominantan uticaj klimatskih prilika na ispitivane parametre. Razlike u brojnosti populacije uočene su na različitim tipovima klopki, godinama posmatranja i lokalitetima. Vizuelnim pregledom biljaka uočena su variranja u brojnosti imaga između lokaliteta i godina. Od ukupno 1.007 registrovanih imaga, 58,68% konstatovano je na području Crepaje i 41,33% u oglednom polju Instituta za kukuruz Zemun Polje. Od ukupno registrovanih 867 imaga u Zemun Polju u periodu od 2005-2007godine, na feromonskim klopkama bilo je 406 ili 46,8%, na žutim lepljivim 443 ili 51,09% i na zelenim lepljivim, Multigard klopkama, svega 18 ili 2,07%. Visok nivo populacije imaga za period od tri godine zabeležen je u Crepaji. Na žutoj lepljivoj klopci registrovano je 8.550 imaga, na zelenoj 12.101, a maksimum brojnosti po godini od 24.028 jedinki detektovan je na feromonskoj klopki. U narednom periodu, tokom 2008-2009 godine, ekstremno visoke temperature tokom vegetacije i niska relativna vlažnost vazduha, zajedno sa nedostatkom kvalitetne hrane, rezultirali su sporadičnim ulovima tokom avgusta do potpunog izostanka leta.

AB  - During 2008 and 2009, efficacy of insecticidal products, based on thiamethoxam and imidacloprid, were tested. Furthermore, effects of entomophatogenic fungus Beauveria bassiana on the infestation intensity of European corn borer (Ostrinia nubilalis), were established over effects of both, 10 different treatments of maize seed (8 treatments and 2 controls) and the application of the fungal inoculum. Trials were carried out on maize crop under field conditions in accordance with the EPPO method. Results obtained in the studies with the product Cruiser 350 FS (350g l-1 thiamethoxam) applied in the amount of 0.9 l per 100 kg of seed and the products Imidor 600 FS and Gaucho 600FS (600g l-1 imidacloprid) applied in the amount of 0.7 l per 100 kg of seed, point out to satisfactory efficacy in controlling ECB and satisfactory effects on maize yields. The intensity of ECB infestation, expressed in percentages, ranged from 50.1% to 74.1%. The interrelation between average percentages of infested plants and obtained yields in both investigation years (2008-2009) in Zemun Polje was established. Results over treatments indicate that the highest percentages (62.2%) of infested plants were observed in the control variant (K1- Captan). Moreover, as expected, the lowest yield was also recorded in this variant. The treatment with the fungicide Maxim combined with the insecticide Criuser proved to be the most efficient. At the same time, the percentage of infested plants was the lowest in this treatment (53.32%) and the yield was the highest (8.610 t ha-1). The infestation level of maize plants in this treatment was significantly reduced over years of investigation in comparison with remaining treatments. Meteorological factors during the years of investigation, especially unfavourable agroecological conditions in 2009, affected the average yield of maize per hectare. The yield (8.314 t ha-1) recorded in the treatment with the inoculum of B. basssiana was almost equal to the one recorded in the treatment with the product Cruiser (8.610 t ha-1), while it was higher than the yield obtained in the treatment with the products Gaucho (7.506 t ha-1) and Imidor (8.259 t ha-1) combined with the fungicide Maxim. These differences were not statistically significant. Seed treatments with the fungal inoculum were not significantly different in any of observed parameters, except in the seed treatment with Captan. The comparison of data obtained in the two-year studies (2008-2009) under conditions of natural ECB infestation, shows prevalence of plants with damages of leaves (type H2) and tassels (type M3-4), which is indicated with the average score of 2.43. According to the average scores, it can be concluded that ECB infestation did not result in damages that would have significantly affected maize yield. In order to establish significance of certain observed parameters, they were compared and their correlations were determined. The greatest negative correlation with the 0.05 probability level (r= -0.96533) was established between the plant damage score and the recorded yield. Since recorded value of coefficients of correlation was approximately 1, it can be stated that the complete functional linear dependence existed among variables. Achieved results show efficiency of insecticides based on thiamethoxam and imidacloprid in the regulation of the infestation level in maize and also point to negative effects of the fungus B. bassiana on entomofauna of maize and its mycoinsecticide activity that could find an application in biocontrol of insect pests of maize.
AB  - Tokom 2008. i 2009. godine, ispitana je efikasnost insekticidnih preparata, na bazi tiametoksama i imidokloprida i entomopatogeno dejstvo Beauveria bassiana na intenzitet napada kukuruznog plamenca (Ostrinia nubilalis) i njihovog uticaja na prinos srednjestasnog hibrida kukuruza. Ispitivanja su izvedena u skladu sa EPPO metodom u poljskim uslovima u usevu kukuruza. Ostvareni rezultati ispitivanog preparata Cruiser 350 FS (350g l-1 tiametoksama) koji je primenjen u količini 0,9 l na 100 kg semena i preparata Imidor 600 FS i Gaucho 600FS (600g l-1 imidokloprida) primenenjenih u količini 0,7 l na 100 kg semena, ukazuju na zadovoljavajuću efikasnost u suzbijanju kukuruznog plamenca i visinu prinosa kukuruza.

AB  - The frequency and incidence of A. flavus and A. niger on barley, maize, soybean, sunflower and wheat grain, the abundance of European corn borer (Ostrinia nubilalis) moths and their interaction depending on weather conditions in the 2008-2012 period were studied. Under the agroecological conditions of Serbia, the species A. niger is more frequent than A. flavus, and concerning the crop species, its frequency is highest in kernels of sunflower, than soybean, maize, barley and wheat. A. flavus was extremely dominant on all plant species in 2012 regarding its frequency: 100% on soybean, 95.3% on maize, 65.2% on barley, 57.1% on sunflower and 45.8% on wheat. Furthermore, the incidence of A. flavus was higher in 2012 than in previous years. The uncommonly high frequency and incidence of A. flavus infestation of maize grain in 2012 were caused by extremely stressful agrometeorological conditions, high temperatures and drought over the period from flowering to waxy maturity of maize. The precipitation factor (Pf = precipitation sum / average monthly temperature) showed that 2012 was extremely arid in June (Pf = 0.57), July (Pf = 1.45), August (Pf = 0.15) and September (Pf = 1.42). European corn borer (ECB) was a second factor causing intensive occurrence of A. flavus on maize grain in 2012. The maximum flight of ECB moths was recorded as early as in July (5,149) and, as a result of this, high damage and numerous injuries were detected at harvest. Those injuries were covered by visible olive-green powdery colonies typical of A. flavus. In the chronology of A. flavus occurrence, these are the first data on its very high frequency and incidence under the agroecological conditions of Serbia. As intensive infections with A. flavus were rare in the past 50 years, the level of aflatoxins in maize grain was low.
AB  - U ovom radu su analizirani učestalost i intenzitet napada A. flavus i A. niger na 180 uzoraka zrna ječma, 1138 kukuruza, 283 soje, 89 suncokreta i 79 pšenice, brojnost leptira kukuruzovog plamenca (Ostrinia nubilalis), kao i njihova interakcija u zavisnosti od meteoroloških uslova u periodu 2008-2012. U agroekološkim uslovima u Srbiji vrsta A . niger je učestalija od vrste A. flavus, a u zavisnosti od biljne vrste pojavljuje se najčešće na zrnu suncokreta, zatim soje, kukuruza, ječma i pšenice. A. flavus je izuzetno bila dominantna na svim biljnim vrstama u 2012, kako po učestalosti, tako i intenzitetu napada. Ova vrsta je u 2012. godini utvrđena kod svih uzoraka soje (100%), nešto manje na zrnu kukuruza (95,3%), zatim na ječmu (65,2%) i suncokretu (57,1%) i najmanje na zrnu pšenice (45,8%). Intenzitet napada A. flavus je, također, bila veća u 2012. u poređenju sa prethodnim godinama. Neuobičajeno visoka učestalost i intenzitet napada A. flavus na zrnu kukuruza u 2012. godini bila je uslovljena izuzetno stresnim agrometeorološkim uslovima, visokim temperaturama i sušom, od cvetanja do voštane zrelosti kukuruza. Kišni faktor (Kf = suma padavina / prosečna mesečna temperatura) ukazuje da je te godine bila izuzetno aridna klima u junu (Kf = 0,57), julu (Kf = 1,45), avgustu (Kf = 0,15) i septembru (Kf = 1,42). Kukuruzov plamenac je drugi činilac koji je uslovio intenzivnu pojavu A. flavus na zrnu kukuruza u 2012. godini. Maksimalni let leptira ovog insekta utvrđen je veoma rano, posebno let druge generacije, već u julu 2012. (5.149 jediniki), a kao posledica toga u vreme berbe su utvrđena i brojna oštećenja na kojima je bio vidljiv razvoj maslinasto-zelenih praškastih kolonija koje su tipične za A. flavus. U hronologji pojave A. flavus ovo su prvi podaci o njenoj jako visokoj učestalosti i intenzitetu napada u agroekološkim uslovima u Srbiji. Intenzivna pojava A. flavus je bila retka u proteklih 50 godina zbog čega je bio i nizak nivo aflatoksina u zrnu kukuruzu.

AB  - Proper planting date is important for maize production. Therefore, field studies were conducted from 1995-2005 to determine the most suitable planting date for six maize hybrids (FAO 300-700 maturity groups) as influenced by infestation level of European corn borer (ECB), Ostrinia nubilalis (Hbn). Significant differences in the levels of ECB infestation, level of damage and grain yield were observed between the planting dates, and the years. The total plant infestation by both generations ECB over the planting dates ranged from 47% to 60%. Plant damage rating was on the average of 2.2 and slightly differed across the planting dates. Yield results indicated that the planting period for maize production in the Vojvodina province was from April 15 to May 5, but the Most Suitable date was the beginning of the third week of April.

AB  - The abundance of pests and the rate of plant damages are controlled by the maize seed treatments with insecticides, as a preventive measure and a measure leading towards the lower population. It is expected that insecticides are efficient when used in relatively small dosages and that are not phytotoxic to seeds and young plants. The aim of the present study was to test the efficiency of imidacloprid and thiametoxam via both, the maintenance of plant spacing and obtained grain yield and also to check the response of certain hybrids to the seed treatment with systemic insecticides. Eight commercial ZP hybrids, four medium early maturity and four full season hybrids, were selected to test imidacloprid (Gaucho 350 FS - 1.0 l per 100 kg seeds) and thiametoxam (Cruiser 350 FS in the amount of 0.6, 0.9 and 1.0 l per 100 kg seeds). Seeds of all hybrids, including the control, were treated with the fungicide Maxim XL 035-FS (150g/100 kg seeds). Strip trials were performed in six locations in south Banat in the 2004-2007 period. The number of plants ha-1 at harvest and grain yield (t ha-1 at 14% moisture), in four replications of 10 m2 each, were recorded and then indices of plant spacing and grain yields for each hybrid over locations and years were calculated. The indices were estimated by the formula of values of plant spacing and the yield in treatments/ values in the control. Plant spacing: the average number of plants in the treatment with imidacloprid Gaucho 600 FS (63 hybrids/locations) and the control was 48,627 ha-1 and 47,812 ha-1, respectively, while the positive difference amounted to 815 plants ha-1 in the treatment. The index of plant spacing was 103.2, and it varied over hybrids, locations and years from 74.9 to 161.4. The corresponding values in the treatment with Cruisera 350 FS (70 hybrids/locations) and the control were 49,945 ha-1 and 49,749 ha-1, respectively. A positive difference in favour of the treatment amounted to 196 plants ha-1. The index of plant spacing was 100.4, and it varied from 82.6 to 132.7. Grain yield: the average grain yield in the treatment with 600 FS and the control was 9,306 t ha-1 and 8,942 t ha-1, respectively. An average positive difference in favour of the treatment amounted to 364 kg ha-1. The index based on the average grain yield amounted to 104.1. The corresponding values in the treatment with Cruisera 350 FS and the control were 9,601 t ha-1 and 9,031 t ha-1, respectively, which means that the positive differences was 570 kg ha-1. According to the average values of obtained plant spacing and grain yields for both insecticides, it can be concluded that a positive response of maize to the seed treatments (364 to 570 kg ha-1) was established under the conditions of a low abundance of soil pests, particularly western corn root worm, during the 2004-2007 period. Although all eight hybrids expressed tolerance to both observed insecticides, it should be stated that the inconsistence of results can create a different impression.
AB  - Nakon prelaska sa višegodišnje monokulture na gajenje kukuruza u plodoredu, pa i u ponovljenoj setvi, brojnost populacije kukuruzne zlatice se smanjila ispod ekonomskog značaja. Ostale su aktuelne samo autoktone zemljišne štetočine.Tretiranje semena kukuruza insekticidima, predstavlja preventivnu meru zaštite od žičnjaka i grčica, kao i od ptica koje vade klijance. Cilj ispitivanja bio je, da se testira efikasnost imidakloprida i tiametoksama preko očuvanja sklopa, ostvarenog prinosa zrna i proveri reagovanje osam hibrida na tretman semena navedenim sistemičnim insekticidima. Sklop biljaka: kod imidakloprida Gaucho 600 FS na 63 (hibrid x godina x lokalitet) pozitivna razlika iznosila je 815 biljaka/ha a kod tiametoksama Cruisera 350 FS 196 biljaka/ha. Indeks sklopa bio je 103.2, kod prvog i 100.4 kod drugog insekticida. Prinos zrna: primenom imidakloprida Gaucha 600 FS ostvarena je pozitivna razlika od 364 kg/ ha, a kod primene tiometoksama Cruisera 350 FS 570 kg/ha. Na osnovu prosečnih vrednosti ostvarenog sklopa biljaka i prinosa zrna može se zaključiti da su svih osam hibrida pokazali tolerantnost na oba ispitivana insekticida, uz napomenu da nekonzistentnost rezultata treba šire analizirati.

AB  - Changes in pest populations occur on a regular basis and can be influenced by various biotic and abiotic factors, including human activites. The objective of this article was to outline several factors that contributed to the population changes in major maize pests over a 50 year period as reported in Serbian literature. Populations of economically important insects, pathogens and weeds were influenced by changes in agronomic practices and introduction of new species. Examples of new pests included: insect species such as western corn rootworm, weed species such as common ragweed and marshelder, and various pathogens including races of Exserohilum turcicum and Bipolaris zeicola. There was also an increase in maize dwarf mosaic virus and barley yellow dwarf virus.

AB  - The European corn borer (ECB) (Ostrinia nubilalis Hbn) is one of the most important pests of maize in Serbia. Therefore, it has been and continues to be an attractive subject of research. The flight of ECB adults has been monitored by light traps at the Maize Research Institute in Zemun Polje, Serbia since 1966. Significant qualitative changes in the ECB voltinism occurred during the last three decades of the 20th century. ECB used to be extremely univoltine with 80-90% moths of the first generation, but lately it has become predominately bivoltine. During these 20 years of monitoring, a total of 52,450 specimens were captured (32,382 females and 20,068 males) and their population varied between 351 moths per year recorded in 2001 and 8,347 recorded in 1987. Ratio between the first and the second generation has been changed so that the larger number is the second generation: on the average 1:5.94 (first: second generation), and ranged between 1:0.34 recorded in 2004 and 1: 21.6 recorded in 1987.

AB  - Vrsta Diabrotica virgifera virgifera LeConte, oligofagna štetočina, dospela je na naše prostore slučajnom introdukcijom devedesetih godina prošlog veka. Za ovu vrstu svojstveno je da formira ekonomski nivo populacije samo u monokulturi kukuruza. Ogled u kojem je praćena brojnost kukuruzne zlatice je trofaktorijelni zasnovan na eksperimentalnoj parceli Instituta za kukuruz u Zemun Polju 1972. godine. Obuhvatao je 54 varijante, šest kombinacija mineralnih đubriva, tri načina postupanja sa žetvenim ostatcima i tri doze primene stajnjaka. Odabrano je 12 varijanti, praćena je brojnost imaga na žutim lepljivim klopkama marke Pherocon AM. Prva pojava imaga u našim uslovima počinje krajem juna, porast brojnosti događa se u julu, maksimum u julu i avgustu mesecu. Brojnost populacije analizirana je po varijantama na osnovu vremena praćenja i povoljnosti vremenskih uslova za gajenje kukuruza. Tokom tromesečnog perioda (juli, avgust, septembar 2004.) ukupno je uhvaćeno 317 jedinki, brojnost se kretala od nule na početku jula do maksimalnih 76, registrovanih 6. avgusta. Nakon ovog perioda brojnost se znatno smanjila i od početka septembra nije više registrovan ni jedan primerak. Pad brojnosti u drugoj polovini avgusta može se tumačiti migracijom jedinki na susedna polja sa svežom svilom ili polenom u cilju dopunske ishrane. Po varijantama ogleda iznosila je od svega osam u varijanti sa najmanje hraniva, do 52, u varijanti sa najviše hraniva. Možemo konstatovati da je nedostatak vlage u avgustu uslovio brže sazrevanje svile, sušenje zemljišta, masovniju migraciju i skraćenje dužine života imaga, što se odrazilo na pad brojnosti i manjeg broja položenih jaja, što se potvrdilo u 2005. godini.

AB  - Monitoring of plant lodging and yield response was performed with the aim to quantify the maize plant response to WCR larvae root damage. Results of plant lodging ranged from 5.39% to 22.26%. Ploughing down of harvest residues slightly decreased percentage of the plant lodging from 12.92% to 15.24% comparing to the removal of harvest residues. Yield response to CR was followed by 565 kg ha-1 prior to and 586 k /ha-1 after the WCR appearance. Yield differences were 2.861 t ha-1 and 2.840 t ha-1, percentage of yield losses was 35.6% and 33.0% in CRO and CR1, respectively.

AB  - The objective of our study was to investigate effect of saprophytic bacterium Serratia liquefaciens derived from sunflower on maize phytopathogenic fungi in vitro and in vivo conditions, as well as, potential biochemical and molecular mechanisms. Obtained results indicate that production of an antibiotic is not a biochemical background of the antagonistic effect. Concurrence advantage of the saprophytic bacterial isolate S. liquefaciens isolated from sunflower, over the parasitic fungus Ph. ambiguum when limited quantities of carbon compounds were used in the joint culture, caused antagonistic effect between these two groups of microorganisms. The de novo synthesis new polypeptides of different molecular weight occurred in interactions with phytopathogenic fungi. The successful activities of isolates of the saprophytic bacterium under in vivo conditions were observed and manifested as lack of disease symptoms (root and stalk rots), and stimulatory effects on the rowth of both, roots and above-ground plant parts. The bacterial isolate S. liquefaciens showed the greatest inhibition rate of colonies growth of fungus Ph. ambiguum under in vivo conditions.
AB  - Ispitivan je antagonistički efekat saprofitne bakterije Serratia liquefaciens, poreklom iz rizosfere suncokreta na fitopatogene gljive kukuruza u in vitro i in vivo uslovima, kao i potencijalni mehanizmi dejstva na biohemijskom i molekularnom nivou. Uočeno je da bakterijska vrsta S. liquefaciens ne poseduje sposobnost sinteze antibiotika. Antagonistički efekat koji je ova vrsta ispoljila prema Ph.ambiguum pri gajenju na hranljivoj podlozi sa različitim koncentracijama glukoze rezultat je postojanja kompeticijskog odnosa. U interakciji sa fitopatogenim gljivama došlo je do de novo sinteze proteinskih frakcija različitih molekulskih težina. Uspešno delovanje ovog bakterijskog izolata na razvoj fitopatogene gljive Ph. ambiguum ustanovljeno je i u in vivo uslovima, koje se ispoljavalo izostankom simptoma bolesti (truleži korena i stabla) i stimulativnom dejstvu na porast korena kao i nadzemnih delova biljke.
