孑孓灵制剂是武汉微生物农药厂用引入的苏云金杆菌以色列变种(Bacillus thuringiensis Var isaelensis)通过液体深层发酵制备的芽胞和伴孢晶体的混合物;它是一种高效的细菌杀虫剂;该制剂被孑孓吞食后可使之死亡,对白鼠、鱼类急性中毒试验安全。国内关于苏云金杆菌以色列变种杀蚊幼虫已有报道;本文重点介绍使用孑孓灵灭蚊幼的效果。实验室内观察方法:用容量1,000毫升的高型烧杯,每杯装入水浮莲池内水体500毫升与取自池内十分活跃的孑孓20条。菌粉现用现配,按
The larvae preparation is a mixture of spores and parasporal crystals prepared by submerged fermentation by the Bacillus thuringiensis Var isaelensis introduced by Wuhan Microbial Pesticide Factory; it is a highly effective bacterial pesticide; the preparation is larvae After swallowing can make the death of rats, fish poisoning safety test. Domestic mosquito larvae have been reported on the Israeli variant Bacillus thuringiensis; this article focuses on the effects of mosquito larvae using mosquito larvae. Laboratory observations: Using a 1,000 ml tall beaker, each cup is filled with 500 ml of water and 20 very larvae in the pool. Powder is now available with, press
