选用６种常用杀虫剂对美洲斑潜蝇幼虫、蛹、成虫和其优势种天敌冈崎姬小蜂成蜂进行室内药效测定．结果表明：采用厂家推荐田间使用的质量分数，对美洲斑潜蝇幼虫杀虫效果（７２ ｈ 后）以威宝、虫螨克和杀虫双较好，幼虫的死亡率分别为９２．１０％ 、９１．９８％ 和８６．９４％ ；敌敌畏和乐斯本其次，幼虫死亡率为６９．０５％ 和６７．６１％ ；灭扫利效果最差，幼虫死亡率仅为４１．６５％ ．经杀虫剂处理后，蛹的羽化率降低１０．００％ ～３５．００％ ．对美洲斑潜蝇成虫的毒效（２４ ｈ 后），杀虫双、虫螨克和灭扫利造成的死亡率为１００．００％ ，威宝为９３．４０％ ，而敌敌畏和乐斯本效果较差，仅为６５．６４％ 和７２．５５％ ． ６种杀虫剂对冈崎姬小蜂成蜂击倒、触杀作用的大小顺序依次为：乐斯本≈敌敌畏＞ 杀虫双＞ 灭扫利＞ 阿维菌素类．
Six common insecticides were used to determine the effects of adult mosquitoes, pupae, adults and their dominant species, Okazaki Hoverfly. The results showed that the insecticidal effect (after 72 h) of Vibrio parapsilock larvae was better than Vibrio pendula, pest mite and insecticidal double, and the larval mortality rates were 92.10% , 91.98% and 86.94%, respectively. The mortality rates of dichlorvos and Lupis were 69.05% and 67.61%, respectively. The killing effect of lavate was the worst, and the larval mortality was only 41.65%. After the insecticide treatment, the pupae emergence rate decreased by 10.00% ~ 35.00%. The toxic effect on adults of L. occidentalis (after 24 h) was 100.00% for mortalities, pests and pests, 93.40% for Viagra, The effect is poor, only 65.64% and 72.55%. Six kinds of insecticides Okazaki Hime’s bee wasps knocked down, the contact effect of the order of magnitude: Lesbian ≈ dichlorvos> insecticidal double> destroy the benefits of avermectins.
