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%).

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.

abstract = "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., 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.
