Abstract

The efficacy of Flumethrin pour on and Coumaphos 50% WP was tested against different stages of Hyalomma dromedarii. With contact method, LC50 values for larvae and adults were 0.04, 0.03 ug/cm2 and 0.05, 1.06 ug/cm2 respectively. The LC50 for coumaphos against the larvae, adults and eggs using dipping method were 44, 63, and 62 ppm respectively. Flumethrin caused significant reduction in oviposition and hatchability in female ticks that survived sublethal concentrations, while sublethal doses of coumaphos had no effect on the reproductive potential of the tick. The results showed that flumethrin was 8 times more toxic than coumaphos.

摘要

测试了氟氯氰菊酯浇泼剂和 50% 蝇毒磷可湿性粉剂对不同发育阶段的单峰驼璃眼蜱的效果。采用接触法，幼虫和成虫的 LC50 值分别为 0.04、0.03 微克/平方厘米和 0.05、1.06 微克/平方厘米。采用浸渍法时，蝇毒磷对幼虫、成虫和卵的 LC50 分别为 44、63 和 62 ppm。氟氯氰菊酯可使存活于亚致死浓度下的雌性蜱产卵量和孵化率显著降低，而亚致死剂量的蝇毒磷对蜱的繁殖潜力无影响。结果表明，氟氯氰菊酯的毒性比蝇毒磷高 8 倍。
