AB  - The 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 LD70 deltamethrin) with filter paper treated with sublethal doses (LD20 and LD50) of the insecticides dichlorvos, malathion, chlorpyrifos-methyl, pirimiphos-methyl and deltamethrin on offspring production of the surviving insects in F1 generation (after 10 weeks) and F2 generation (after 16 weeks) in untreated wheat grain was examined under laboratory conditions. Offspring reduction of laboratory weevils was highest at 96% in the F1 generation after parents' contact with LD50 dichlorvos, and lowest in F2 generation after contact with LD50 pirimiphos-methyl with 84% more insects than in the control. The highest offspring reduction of selected weevils from Belgrade Port, 83%, was recorded in F1 generation after treatment with LD50 dichlorvos and chlopyrifos-methyl, and the lowest in F1 and F2 generations after contact with LD50 pirimiphos-methyl, around 44%. The highest offspring reduction of the selected weevils from Bijeljina, 100%, was found in F1 and F2 generations after contact with LD50 dichlorvos, malathion and deltamethrin, and the lowest again in F1 and F2 generations after contact with LD20 chlorpyrifos-methyl, in which case insect numbers were some 130% higher than in the control. The results indicate that sublethal insecticide doses, apart from a significant decrease in their efficacy against treated granary weevil populations, may also provoke an increase in insect numbers in the following generations.

AB  - The insecticidal effectiveness of two natural zeolite formulations (Minazel plus and Minazel), applied to wheat at selected rates of 0.25, 0.50 and 0.75 g/kg, and a diatomaceous earth formulation (DE) (Protect-It (TM)), applied at the recommended rates of 0.15 g/kg for Sitophilus oryzae, 0.20 g/kg for Rhyzopertha dominica and 0.30 g/kg for Tribolium castaneum, were tested under laboratory conditions (24 +/- 1 degrees C temperature and 45 +/- 5% relative humidity). The highest adult mortality was observed after the longest exposure period of 21 days and 7 days of recovery, when all three zeolite dosage rates and the recommended DE dosage caused 97-100% mortality of S. oryzae and 94-100% of T. castaneum. On the other hand, 100% mortality was not achieved in any test variant involving R. dominica; the highest (about 92%) was detected for DE, while 52% and 79% mortality was achieved with the zeolites at the highest rate of 0.75 g/kg. Progeny reduction by GT 90% was achieved after 21 days of contact of all three beetle pests with DE-treated wheat, while the same level of reduction was achieved for S. oryzae and T. castaenum only after contact with the highest rate of the zeolite product, Minazel. Thus the two zeolite formulations are comparable to diatomaceous earth in controlling adult S. oryzae. R. dominica and T. castaneum, but only the Minazel formulation could effectively protect wheat from attack by S. oryzae or T. castaneum, and only with a higher rate of application than for the DE formulation.
