摘要
目的 净普力与常用 4种化学杀虫剂敌敌畏、溴氰菊酯、氯菊酯、残杀威对本地致乏库蚊、白纹伊蚊野生种群幼虫、卵、蛹的杀灭效果比较 ,观察在室内外条件下的残效时间。方法 浸渍法。结果 净普力、敌敌畏、溴氰菊酯、氯菊酯、残杀威对致乏库蚊的LC50 (μg/ml)值分别为10 46、0 .2 847、0 .0 0 13 89、0 .111、0 .5 42 9;对白纹伊蚊的LC50 (μg/ml)值分别为 12 0 6、0 .0 42 89、0 .0 0 0 64 5 5 9、0 .493 1、0 .978。但净普力杀卵、杀蛹能力与残杀威、溴氰菊酯相当 ;净普力对致乏库蚊、白纹伊蚊的室内残效时间分别为 15、14d ,室外残效分别为 12、8d ,较其他 4类杀虫剂残效长。结论 天然酶制剂可逐步用于除四害工作。
Objective To compare the killing effect of the zymplex and other the four insecticides against larvae, eggs, pupae of Culex quinquefasciatus, Aedes albopictus.Methods Immersion method. Results The LC 50 (μg/ml) of the zymplex,dichlorvos,deltamethrin,permethrin,propoxur against C.quinquefasciatus were 1 046, 0.284 7, 0.001 389, 0.111, 0.542 9 respectively, and against A.albopictus were 1 206, 0.042 89, 0.000 645 59, 0.493 1, 0.978 respectively. The effect of zymplex on killing eggs, pupae was much higher than those of the other four insecticides, its residual period against C.quinquefasciatus and A.albopictus could last 15,14 days (laboratory condition); 12,8 days (field),which were longer than those of the four other insecticides. Conclusion Zymplex can be introduced into the pest control operation.
