ABATE颗粒剂杀灭蚊幼虫持效观察

Observation on Long-Lasting Activity of Abate Granules against Mosquito Larvae

目的 :测定ABATE颗粒剂在室内不同水质中 3种浓度对淡色库蚊幼虫杀灭效果。方法 :浸液法。结果 :在清水中按 1g/m2 给 1%ABATE颗粒剂 ,杀死蚊幼虫 10 0 %的持效时间为 90d ;同剂量下在灌溉水中为 6 0d ;在 2 0 %泥浆水中按 2 g/m2 投放颗粒剂 ,杀死蚊幼虫 10 0 %的持效时间为 2 1d。结论 :该药剂对蚊幼虫杀灭效果好 ,持效时间长 ,使用浓度低。

Objective: Killing activity of abate granules against Culex pipiens palliens larvae in 3 concentrations and different waters in laboratory was determined. Method:Soaking test.Result: Long-lasting active time of 100% killing larvae was 90 days at the dose of 1.0 g/m 2 of 1% Abate granules in clear water, and 60 days in irrigation water, 21 days at the dose of 2.0 g/m 2 in mud water. Conclusion: The insecticide possesses good larvicidal activity and has long-lasting active time and low concentration used.
