以斑翅果蝇和黑腹果蝇为试虫,采用胃毒触杀联合毒力测定方法分别测定了5种类型共8种杀虫剂对黑腹果蝇及斑翅果蝇实验室种群幼虫和成虫的毒力,田间药效试验测定6种杀虫剂防治果蝇的效果。结果表明:杀虫剂对果蝇幼虫毒力比对成虫毒力强,且斑翅果蝇比黑腹果蝇对杀虫剂更敏感,氨基甲酸酯类杀虫剂茚虫威,烟碱类杀虫剂噻虫嗪、茚虫威和吡虫啉对果蝇的致死作用效果低下,烟碱类杀虫剂啶虫脒对黑腹果蝇致死效应高于斑翅果蝇;菊酯类杀虫剂高效氯氟氰菊酯致死毒力高于菊酯类杀虫剂联苯菊酯,生物制剂多杀霉素和甲维盐致死毒力最强。
Using Drosophila melanogaster and Drosophila melanogaster as test insects, five kinds and five kinds of insecticides were used to determine the larval population and the larval population of Drosophila melanogaster and Drosophila melanogaster, respectively. Adult toxicity, field efficacy test to determine the effect of six kinds of insecticides to control fruit flies. The results showed that the toxicity of insecticides to Drosophila larvae was more virulent than that of adults, and Drosophila melanogaster was more sensitive to insecticides than Drosophila melanogaster. The insecticides indoxacarb and nicotine The insecticides thiamethoxam, indoxacarb and imidacloprid have a low lethal effect on fruit flies. The lethal effect of the nicetine insecticide acetamiprid on Drosophila melanogaster is higher than that of Drosophila melanogaster; the pyrethroid insecticides Cyhalothrin cypermethrin virulence than pyrethroid insecticide bifenthrin, the biological agents spinosad and methylvimentate virulent virulent.
