本文采用18种杀虫剂,测定了它们对两种黑木耳害虫——黑光甲和食丝谷蛾的毒力和药效。试验了有关农药混用对防治黑光甲的增效作用。结果表明:溴氰菊酯、氯氰菊酯、百树菊酯、杀灭菊酯、杀螟松、二嗪农、氧化乐果、乐果、敌敌畏和杀虫双对黑光甲成虫和幼虫有较高的药效。4种拟除虫菊酯、杀螟松、二嗪农,氧化乐果,敌敌畏和敌百虫对食丝谷蛾幼虫有较高的药效。溴氰菊酯与西维因混用,敌百虫与乐果混用对防治黑光甲有明显的增效作用。
Twenty-eight insecticides were used in this study to determine their toxicity and efficacy to two black fungus pests, A. niloticus and H. guttatum. Test the effectiveness of the pesticide mixture on the prevention and treatment of black light. The results showed that deltamethrin, cypermethrin, cypermethrin, fenvalerate, fenitrothion, diazinon, omethoate, dimethoate, dichlorvos and insecticidal double pairs of adults and larvae had higher Efficacy. Four kinds of pyrethroid, fenitrothion, diazinon, omethoate, dichlorvos and trichlorfon had high efficacy on H. guttatum larvae. Deltamethrin mixed with Cimetidine, trichlorfon mixed with dimethoate prevention and treatment of black light A synergistic effect.
