苏芸金杆菌以色列变种1897株(Bacillus thu-ringiensis Var.israeleasis以下简称B.t.i.)是目前首选的生物防制剂。它对蚊幼具有很高的毒力和速杀作用,但持效短。据研究,其持效与靶生物的摄食习性和昆虫的生理有关。本文就中华按蚊和白纹伊蚊幼虫的摄食习性与B.t.i.不同制剂的毒效关系进行了比较。
Bacillus thuringiensis strain 1897 (Bacillus thu-ringiensis Var.israeleasis hereinafter referred to B.t.i.) is currently the preferred biological control agent. It mosquito has a very high virulence and quick kill effect, but short-acting. According to the study, its persistence is related to the feeding habits of target organisms and the physiology of insects. In this paper, the feeding habits of Anopheles sinensis and Aedes albopictus larvae were compared with those of B.t.i. different formulations.
