摘　　要：５种杀虫剂对烟青虫的毒力试验表明：质量分数为 ８０％～ ８３％的高效氯氰菊酯和 ８６．７％的氰成菊酯分别稀释２ ０００和１０００倍对烟青虫的防治效果较好，ＬＣ_（５０）分别为０．０３２ ２μｇ·头^（－１）和０．０５８ ２ μｇ·头（－１），久效磷和乙酸甲胺磷稀释１０００倍的效果次之，吡虫啉效果最差．The experiment was done to test the toxicity of 5 insecticides on tobacco budworm and the results indicated that Alpha-cypermethrin of 80% - 83% and fenvalerate of 86.7% have good prevention effect on tobacco budworm, their LC_(50) are 0.032 2 μg and 0.058 2 μg respectively, The prevention effect of monocrotophos and acephate copmes next of the former.The study can afford some basis to the pest control in the fields to some degree.
