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 9.5 0和 9.2 2min ,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 8.0 6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 2 4h死亡率均达 92 %～ 10 0 %。 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。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/m 2 on the surface of plant for above public health insects by forced touching method. Results:It was showed that the KT 50 of cis-chlovaporthrin were 9.5 min for Culex pipiens pallens and 9.22min for Musca domestica vicina respectively,the KT 50 of trans-chlovaporthrin was 6.28min for Culex pipiens pallens and 8.72min for Musca domestica vicina respectively,the KT 50 of dextro-trans-chlovaporthrin was 8.06min for Culex pipiens pallens and 10.89min for Musca domestica vicina respectively,the KT 50 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%.
