拜虫杀和杀飞克对3种卫生害虫的药效报告

Efficiency of Responsar and Solfac against Three Public Health Insects

本文报道了两种菊酯类卫生杀虫剂，在不同载体表面对３种卫生害虫的触杀试验。结果：（１）拜虫杀在玻璃板面上６．２５ｍｇ／ｍ２时对家蝇速效ＫＴ（５０）为３．３ｍｉｎ；淡色库蚊为４．３ｍｉｎ；持效均达４９天；对德国小蠊ＫＴ（５０）为５．６ｍｉｎ，持效４２天。在木板表面１２．５ｍｇ／ｍ２时，对家蝇速效ＫＴ（５０）为４．３ｍｉｎ，对淡色库蚊为４．６ｍｉｎ，对前者持效４９天，后者４２天。对德国小蠊ＫＴ（５０）为４．９ｍｉｎ，持效３５天。在水泥板面２５ｍｇ／ｍ２时，对家蝇速效ＫＴ（５０）为４／ｍｉｎ，对淡色库蚊为５．０ｍｉｎ，前者持效３５天，后者４２天。对德国小蠊速效ＫＴ（５０）为６．４ｍｉｎ，持效２１天。（２）杀飞克在玻璃面上７．５ｍｇ／ｍ２时，对家蝇速效ＫＴ（５０）为３．７ｍｉｎ，对淡色库蚊为５．１ｍｉｎ，持效均达４９天。在木板面上１５ｍｇ／ｍ２时，对家蝇速效ＫＴ（５０）为４．２ｍｉｎ，对淡色库蚊为６．０ｍｉｎ，对前者持效４９天，后者为４２天。在水泥板面３０ｍｇ／ｍ２时，对家蝇速效Ｋｔ（５０）为４．４ｍｉｎ，对淡色库蚊为５．０ｍｉｎ，对前者持效３５天，后者４２天；对德国小蠊速效ＫＴ（５０）为６．４ｍｉｎ，持效２１天。

This paper deals with the contactive trial effect of two isomer of cyfluthrin for 3 public health insects on different surfaces. The results showed that the KT(50) of Responsar(sc) were 3.3 min for Musca domestica vicina and 4. 3min for Culex pipiens pallens respectively at 6.25mg/m2 on the surface of glass. Both of the lasting effect were 49 days. While the KT(50) was 5.6min for Blattella germanica,its lasting effect was 42 days,When it was at 12.5mg/m2 on the surface of plank,the KT(50) were 4.3min for Musca domestica vicina and 4.6min for Culex pipiens pallens, while the lasting effect were 49 days for the former and 42 days for the latter,The KT(50) was 4.9min for Blattella germanica, its lasting effect was 35 days.When it was at 25mg/m2 on the surface of cement,the KT(50) were 4.4min for Musca domestica vicina and 5.0 min for Culex pipiens, pallens, while the lasting effect were 35 days for the former and 42 days for the latter, For the Blattlella germanica, the KT(50) was 6.4 min and the lasting effect was 21 days. For the Solfac (wp) at 7.5mg/m2 on the surface of glass, the KT(50) was 3.7 min for Musca domestica vicina, 5.1 min for Culex pipiens pallens respectively. Both the lasting effect were 49 days.When it was at 15mg/m2 on the surface of plank, the KT(5O) were 4.2 min for Musca domestica vicina and 6.0 min for culex pipiens pallens. The lasting effect were 49 days for the former and 42 days for the latter.When it was at 30mg/m2 on the surface of cement,the KT(50) were 4.4 min for Musca domestica vicina and 5.0 min for Culex pipiens pallens. The lasting effect were 35 days for the former and 42 days for the latter. For the Blattella germanica,the KT(50) was 6.4 min and the lasting effect was 21 days.
