摘　　要：用药膜法室内测定了新型生物杀虫剂2.5%菜喜悬浮剂(主要成分为多杀菌素,spinosad)对储粮害虫嗜虫书虱、米象、锯谷盗的作用效果。结果表明菜喜对嗜虫书虱、锯谷盗和米象触杀毒力LC50分别为0.0022、0.0046、0.0059mg/m2。对书虱的防治效果明显高于对其他两种储粮害虫的防治效果。本试验结果对多杀菌素在储粮害虫防治方面的合理应用提供了基本依据。Spinosad is a commercial biological insecticide produced by fermentation culture of actinomycete Saccharopolyspora spinosa. To evaluate the effect of spinosad in controlling stored grain pests, the touch effects of 2.5% spinosad were tested in laboratory on three main stored grain insects Liposcelis entomophila, Oryzaephilus surinamensis, and Sitophilus oryzae. Results show that the LC50s for the three species are respectively 0.0022, 0. 0046, and 0. 0059 mg/m^2. It is indicated that spinosad is effective in pest control for the three insects, obviously more effective for L. entomophila than for other two insects.
