摘　　要：采用室内生物测定的方法,研究了4种植物源农药(苦参碱、鱼藤酮、藜芦碱和除虫菊素)对食用菌重要害虫黑腹果蝇(Drosophila melanogaster Meigen)的生物活性。结果表明:苦参碱、鱼藤酮、藜芦碱和除虫菊素对黑腹果蝇卵的LC50分别为243.355 mg/L、17.703 mg/L、3.360 mg/L和17.548 mg/L;对幼虫的LC50分别为40.166 mg/L、19.782 mg/L、5.604 mg/L和89.972 mg/L;对成虫的LC50分别为12.823 mg/L、8 302.520 mg/L、7 000.039 mg/L和102.377 mg/L。说明4种植物源农药中藜芦碱对黑腹果蝇卵和幼虫的生物活性最高,而苦参碱对成虫的杀虫活性高,2种药剂在食用菌害虫防治实践中均具备较好的应用前景。The bioactivities of four botanical pesticides（Matrine,Rotenone,Veratrine and Pyrethrins）against an important mushroom pest,Drosophila melanogaster（Diptera：Drosophilidae）,were evaluated by means of bioassay in laboratory.The results indicated that the LC50 for Matrine,Rotenone,Veratrine and Pyrethrins against eggs was 243.355 mg/mL,17.703 mg/mL,3.360 mg/mL,17.548 mg/mL,respectively.The LC50 for larvas was 40.166 mg/mL,19.782 mg/mL,5.604mg/mL,89.972 mg/mL,respectively.And the LC50 for adults was 12.823 mg/mL,8 302.520 mg/mL,7 000.039 mg/mL,102.377 mg/mL,respectively.Veratrine had the highest bioactivities against eggs and larvae while Matrine had the best effect on adults,both of the two pesticides have a good prospect on the control of mushroom pest.
