Bodroza-Solarov, Marija; Kljajic, Petar; Andric, Gor an; Filipčev, Bojana; Simurina, Olivera; Prazic Golic, Marijana; Adamovic, MilanQuality parameters of several wheat grain lots (low vitreous and high vitreous grains, non-infested and infested with rice weevils, (Sitophilus oryzae L.) treated with inert dusts (natural zeolite, two diatomaceous earths ... -
Effects of 50°C temperature on Sitophilus granarius (L.), Sitophilus oryzae (L.) and Sitophilus zeamais (Motsch.)
Prazic Golic, Marijana; Andric, Goran; Kljajic, PetarAdults of laboratory populations of granary weevil (S. granarius), rice weevil (S. oryzae) and maize weevil (S. zeamais) were exposed at the temperature of 50°C to determine lethal time (parameters LT20, LT50 and LT99) ... -
Effects of Spinosad and Abamectin on different Populations of Rice Weevil Sitophilus oryzae (L.) in Treated Wheat Grain
Andric, Goran; Kljajic, Petar; Prazic Golic, MarijanaIn laboratory conditions (25±1ºC and 60±5% r.h.) effects of natural insecticides spinosad and abamectin on five S. oryzae populations (laboratory, Šid, Gornji Milanovac, Žabari and Novi Pazar) were investigated. Both ... -
Effects of Sublethal Doses of Contact Insecticides on Offspring Production of Different Granary Weevil Populations
Kljajic, Petar; Peric, IlijaThe effects of prior contact of granary weevil (Sitophilus granarius L.) parents from a laboratory population, a Belgrade Port population (selected with LD70 pirimiphos-methyl) and a Bijeljina population (selected with ... -
Efficacy of Different Insecticides in Controlling Pollen Beetle (Meligetes aeneus F.) in Rapeseed Crop
Milovanovic, Predrag; Kljajic, Petar; Andric, Goran; Prazic-Golic, Marijana; Popovic, TatjanaSince pollen beetle, M. aeneus, is usually controlled by insecticides, the efficacy of several compounds with different modes of action against adult beetles was studied in a threeyear field study. The selected insecticides ... -
Efficacy of Spinosad and Abamectin against Different Populations of Red Flour Beetle (Tribolium castaneum Herbst) in Treated Wheat Grain
Andric, Goran; Kljajic, Petar; Prazic-Golic, MarijanaThe efficacy of spinosad and abamectin against T. castaneum adults from a laboratory population with normal susceptibility to contact insecticides and against malathion-resistant populations from Nikinci and Jakovo was ... -
Management of Western Corn Rootworm (Diabrotica virgifera virgifera)
Sivcev, Ivan; Kljajic, Petar; Kostic, Miroslav; Sivcev, Lazar; Stankovic, SladjanWestern corn rootworm (WCR) was registered for the first time in Europe near the Surčin international airport in Serbia in 1992. The spread of WCR on the territory of Serbia and its population density increased fast. The ... -
