摘要：

研究4种植物源杀虫剂对褐飞虱的毒力，为田间使用植物源杀虫剂防治褐飞虱提供参考。在室内条件下，采用稻茎浸渍法和药膜法测定了4种植物源杀虫剂对褐飞虱3龄若虫和成虫的毒力。两种方法测定结果表明，鱼藤酮对褐飞虱3龄若虫和成虫的毒力最低，LC50分别为10.7791、14.9197、21.4638 mg/L，毒力最高的为藜芦碱，LC50分别为0.7688、1.1852、1.4366 mg/L。4种植物源杀虫剂中藜芦碱、苦参碱和烟碱?苦参碱对褐飞虱具有较好的防治效果。

Abstract:

In order to provide reference for controlling N. lugens, the toxicities of 4 kinds of botanical insecticides Against Nilaparvata lugens (St?l) were studied. Rice stem dipping method and toxic film method were used to test the toxicities of 4 kinds of botanical insecticides on the third instar nymphs and adults of N. lugens under laboratory conditions. The results tested by rice stem dipping method and toxic film method showed that the weakest toxicity was rotenone on the third instar nymphs and adults of N. lugens, and the values of LC50 were 10.7791, 14.9197 and 21.4638 mg/L, respectively. The toxicity of veratrine was strongest, and the values of LC50 were 0.7688, 1.1852 and 1.4366 mg/L, respectively. Among 4 kinds of botanical insecticides on the N. lugens, veratrine, matrine and nicotine?matrine had a better control effect.
