摘　　要：赤拟谷盗是一种重要的世界性储粮害虫,防治困难。本文采用浸渍法测定了番茄茎叶、芦苇全株、水杉叶、皂荚果实等4种植物材料水提液与两种杀虫剂混用对赤拟谷盗的毒力效应。结果表明,各提取液与40%辛硫磷乳油1000倍液、5%氯氰菊酯乳油500倍液以不同比例混配时,均表现出不同程度的增效作用。药液与植物提取液以4∶1、1∶1体积比混配时,增效作用显著,是赤拟谷盗防治措施的有益探索。As an important worldwide stored grain and product pest,Tribolium castaneum is very difficult to control.The toxicity influences of 4 kinds of plant water extracts on two chemical insecticides,40% phoxim EC and 5% cypermethrin EC,tomato stems and leaves,reed whole plant,metasequoia leaves and honey locust fruits were determined.The results showed that all mixtures of plant water extracts and 40% phoxim EC 1000 times diluent or 5% cypermethrin EC 500 times diluent in different proportions gave various degrees of synergy.When the ratios of insecticides diluent to plant water extracts were 4∶ 1 or 1∶ 1 in volume,the synergies were significant.
