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  - 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%).

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%., 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%).",
