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。

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.
