克拉玛依市簇鬃客蚤对4种常用杀虫剂的敏感性调查

Susceptibility of Xenopsylla skrjabini to four commonly used insecticides in Kalamay

目的了解克拉玛依地区簇鬃客蚤对常用杀虫剂的敏感性水平。方法用丙酮配制的药液100μl加在直径35 mm的滤纸药膜上,20 min后放入50 ml离心管盖中,接15只左右成蚤于试管(底部有20个0.5mm小孔以通气)中,旋紧盖子并倒置。结果簇鬃客蚤对残杀威、高效氯氰菊酯、溴氰菊酯和敌敌畏的LC50分别为0.002 8、0.041 3、0.073 0和0.049 1μg/cm2。结论研究结果可为簇鬃客蚤化学防治的药剂选择提供参考。

Objective To understand the susceptibility of Xenopsylla skrjabini to four commonly used insecticides in Kalamay. Methods The bioassay was carried out with filter paper dipped with insecticides. Results The LC50 s of propoxur,β- cypermethrin,deltamethrin and dichlorphos to Xenopsylla skrjabini were 0. 002 8,0. 041 3,0. 073 0and 0. 049 1μg / cm2 respectively. Conclusion The bioassay result would be helpful for insecticide choice in flea control.
