摘要: 本文系统地报道了毒死蜱对蚊、蝇和蟑螂的药效。实验室试验结果表明,毒死蜱对淡色库蚊幼虫的LC50为0.0034ppm;对家蝇雌、雄虫的LD50分别为0.0245和0.0197μg/虫;对德国小蠊雌、雄虫的LD60分别为0.2142和0.1455μg/虫;对蚊、蝇和蟑螂在4种载体表面具有相当长的残留药效;按13mg/m3剂量喷雾后,对蚊、蝇的KT50分别为4.2和4.7min,24h死亡率均达100%,毒死蜱为国内新近合成的有机磷杀虫剂,成本较低,杀虫谱广,值得推广应用。

Abstract: The present paper reported systematically the toxic effect of chlorpyrifos formula on mosquitoes.flies and cockroaches.Bioassay of this pesticide in our laboratory showed that the LC50 of the larvae of Culex pipiens pallens was 0.0034ppm;The LD50 to female al1d male of Musca domestica were 0.0245 and 0·0197ug/insect respectively;and the LD50 to female and male of Blattella germanica were 0.2142 and 0.1455 ug/insect.Being used in 4 kinds of carrier to control mosquitoes,flies and cockroaches,it could keep residual activity for a long time. Spraying for mosquitoes and flies with the dose of 13mg/m3,we found that the KT50 were 4.2 and 4.7 min respectively and it caused 100% mortality during 24hours.
