Sažetak
This study was initiated in order to determine how long several grain protectants will provide acceptable protection against Sitophilus oryzae (L.), Rhyzopertha dominica (F.), and Tribolium castaneum (Herbst.), when applied to clean white winter wheat of 13.6% moisture content. The treatments in the experiment were: mixture of diatomaceous earth and deltamethrin (DE/DM insecticide) applied at 100 ppm containing 90 ppm of DE and 0.1 ppm of deltamethrin active ingredient (a.i.) ; spinosad technical 92% powder applied at 1 ppm a.i. ; Storicide II a mixture of chlorpyrifos methyl (CM) and deltamethrin (DM), applied at 3 ppm CM and 0.5 ppm DM a.i. ; Actellic 5 E (pirimiphos methyl) applied at 10 ppm a.i. Bioassays were initiated immediately after treatment (zero day), 30, 120, 180 and 360 d after the initial treatment and were maintained at 30±1°C and 70±5% air relative humidity during the twelve months. The treatment of wheat with DE/DM mixture and Storicide II provided effective protection against the adults and the progeny of all three species. Actellic at zero day controlled adults and the progeny of S. oryzae and T. castaneum (96% to 100%). However it did not control the adults and the progeny of R. dominica (38% adult’s mortality and 96% progeny reduction). The effectiveness of Actellic on 360 d old deposit on grains was reduced against adults of S. oryzae to 12%, R. dominica to 45%, and T. castaneum to 38% and did not control completely their progeny. Spinosad did not control the adults and the progeny of S. oryzae and T. castaneum at zero day and 360 d. However, the effectiveness against adults and the progeny of R. dominica was 100% at zero and 360 d. The treatment of wheat with DE/DM mixture and Storicide II provided 100% protection against the adults and the progeny of all three species.
