苏云金杆菌以色列变种(血清型H—14)(以下称苏云金杆菌H—14)对蚊幼虫有高度毒效,国内外已做了很多不同规模的现场试验,国外已有几种剂型的商品,具有较好的应用前景。由于苏云金杆菌H—14的毒性机制主要是蚊幼虫吞食本菌的伴孢晶体,这与感染性因子有所不同,而有些类似于化学杀虫剂。为了预测在连续使用的情况下, The Bacillus thuringiensis variant (serotype H-14) (hereinafter referred to as Bacillus thuringiensis H-14) is highly toxic to mosquito larvae. Many field experiments have been done at home and abroad. Several dosage forms have been developed in foreign countries, Better application prospects. Due to the toxic mechanism of Bacillus thuringiensis H-14 is mainly mosquito larvae swallow the spore of the bacteria, which is different from the infectious agents, and some similar to chemical pesticides. In order to predict the continuous use of the case,
