Abstract: Objective:To study the poison effect of different isomerides of chlovaporthrin to mosquitoes and flies and cockroaches.Method:The effect of killing with the poison of four isomerides was studied at 5.0mg·ai/m2 on the surface of plant for above public health insects by forced touching method.Results:It was showed that the KT50 of cis-chlovaporthrin were 9.5 min for Culex pipiens pallens and 9.22min for Musca domestica vicina respectively,the KT50 of trans-chlovaporthrin was 6.28min for Culex pipiens pallens and 8.72min for Musca domestica vicina respectively,the KT50 of dextro-trans-chlovaporthrin was 8.06min for Culex pipiens pallens and 10.89min for Musca domestica vicina respectively,the KT50 of Le-trans-chlovaporthrin was 5.75min for Culex pipiens pallens and 10.44min for Musca domestica vicina.The 24h mortalities of all the mosquitoes and flies on the touching surface were 92%-100% except on the surface of cis-chlovaporthrin.Conclusion:All the effects of four isomerides for Blattella germanicas were not satisfactory,the 72h mortality was below 80%.
摘要: 目的:测定药物分别为5.0mg·ai/m2的4种二氯炔戊菊酯异构体在油漆三合板面上对蚊、蝇和蜚蠊的毒杀效果。方法:强迫接触法。结果:顺式二氯炔戊菊酯对蚊、蝇的KT50为9.50和9.22min,反式二氯炔戊菊酯为6.82和8.72min,右旋反式二氯炔戊菊酯为8.06和10.89min,左旋反式二氯炔戊菊酯为5.75和10.44min;除顺式二氯炔戊菊酯外,其余接触面所试蚊、蝇的24h死亡率均达92%~100%。4种二氯炔戊菊酯异构体对德国小蠊的毒杀效果均不理想,72h死亡率均未超过80%。结论:4种二氯炔戊菊酯异构体对蚊、蝇均具有较好的毒杀效果,但不同异构体对蚊、蝇的毒杀效果存在差异;对德国小蠊的毒杀效果均不理想。
