倍硫磷和吡丙醚对蝇幼虫的杀灭效果

The bioassay effect of fenthion and pyriproxyfen against Musca domestica maggot

目的测试5%倍硫磷颗粒剂和5%吡丙醚微乳剂杀灭蝇幼虫的效果。方法将杀虫剂按比例加入蝇幼虫培养基质,观察蝇幼虫的死亡情况。结果当5%倍硫磷颗粒剂使用剂量为1.67 kg/m3时,72 h蝇幼虫死亡率为96.7%;5%吡丙醚微乳剂使用剂量为83 g/m3时,72 h蝇幼虫死亡率为83.3%。结论 5%倍硫磷颗粒剂和5%吡丙醚微乳剂对家蝇幼虫具有良好的杀灭效果。

Objective To evaluate the effect of 5% fenthion granules and 5% pyriproxyfen microemulsion on killing Musca domestica maggots. Methods The insecticide was mixed with propagation substrate of maggot in proportion, and the mortality was observed at 24,48,72 h. Results When the 5% fenthion granules were applied at the dose of 1.67 kg/m3 ,the maggot 72 h mortality was 96. 7% ;5% pyriproxyfen microemulsion at the dose of 83 g/m3 ,the maggot 72 h mortality was 83.3%. Conclusion Fenthion and pyriproxyfen hold high killing effect on the maggots.
