由于杀虫剂污染环境和蚊虫产生抗药性,几种高效杀虫剂在某些地区的使用受到限制。在寻找新杀虫剂的过程中,发现合成除虫菊酯类对昆虫毒效高且有持效,这类化合物中最有希望的是长效菊酯。本文报道它对哥伦比亚骚蚊(Psorophra columbiae)和四斑按蚊(Anopheles quadrimaculatus Say)的毒效测定。
The use of several highly effective pesticides has been limited in some areas due to insecticide-polluting environments and mosquito-resistance. In searching for new insecticides, pyrethroids were found to be highly potent and persistent against insects, and the most promising of these compounds is the pyrethroid. This paper reports its toxic effect on Psorophora columbiae and Anopheles quadrimaculatus Say.
