中文摘要：应用粉剂药膜法，一种食品级惰性粉——4号粉相应剂量处理赤拟谷盗Tribolium castaneum (Herbst)、烟草甲Lasioderma serricorne (Fabricius)、锯谷盗 Oryzaephilus surinamensis (Linnaeus)的卵和1龄幼虫，赤拟谷盗、锯谷盗、烟草甲的卵平均孵化率均在97%以上，处理后卵孵化的１龄幼虫平均死亡率均在96%以上；处理3种害虫的1龄幼虫其平均死亡率均在99%以上。结果表明食品级惰性粉对3种试虫卵的孵化率几乎没有影响，但对其1龄幼虫有较好的防治效果。通过混粮法应用正交试验研究发现，惰性粉剂量和小麦含水量对赤拟谷盗F₁代防治效果均有显著影响。当小麦处于安全水分时（含水量12%～14%），100～150 mg/kg 4号粉能有效防治赤拟谷盗F₁代。

英文摘要：The eggs and first instar larvae of Tribolium castaneum (Herbst)、Lasioderma serricorne (Fabricius) and Oryzaephilus surinamensis (Linnaeus) were treated with a foodgrade inert dust (No. 4) using a dry, residual film bioassay. The hatching rates of all three species was over 97%, mortality of just hatched larva over 96% and mean mortalities of first instar larvae over 99%. The results show that the food grade inert dust had no effect on the hatching rate of these three insects, but killed almost 100% of first instar larvae. The combined influence of inert dust and wheat moisture content on a T. castaneum F₁ generation was investigated using orthogonal tests; the results show that both factors significantly inhibited the development of F₁ generation. When the moisture content of wheat was between 12% and 14%, 100 mg/kg to 150 mg/kg of inert dust can effectively inhibit the development of the F1 generation of T. castaneum.
