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。
In this paper, two kinds of insecticides of pyrethroids were reported, which were tested on the contact of three kinds of pests on different carriers. The results showed that: (1) KT (50) of housefly was 3.3min at the rate of 6.25mg / m 2 on the glass surface and 4.3min at Culex pipiens pallens The KT (50) of the cockroach was 5.6 minutes and the persistence was 42 days. At 12.5 mg / m2 of wood surface, the KT (50) for housefly was 4.3 min, 4.6 min for Culex pipiens pallens, and 49 days for the former, the latter 42 days. KT (50) against Blattella germanica was 4.9 min for 35 days. The KT (50) was 4 / min on houseflies and 5.0 min on Culex pipiens pallens at 25 mg / m2 on cement board, the former for 35 days and the latter for 42 days. The effective KT (50) against Blattella germanica was 6.4 min for 21 days. (2) KF (50) was 3.7min on housefly and 7.5min on housefly at Culex pipiens pallens 7.5mg / m2 on the glass surface. The retention rate reached 49 days. At 15 mg / m2 on a wooden board, the effective KT (50) for houseflies was 4.2 min for Culex pipiens pallens, 6.0 min for Culex pipiens pallens, and 49 days for the former, the latter 42 days. The effective Kt (50) for houseflies was 4.4 min for Culex pipiens pallens, 5.0 min for Culex pipiens pallens, and 35 days for the former for 42 days, 50) for 6.4min, hold 21 days.
