The comparative study of the larvicidal action of B. thuringiensis var. israelensis on A. aegypti and A. stephensi shows the greater sensitivity of A. aegypti, with 100% of mortality in 30 to 40 min. at high doses. But, for both species of Mosquito, the toxicity of these bacteria is very high, as shown by the mortality regression curves and by the LC50. This toxicity is associated with the crystals and can be extracted from them by dilute alkali solution, like the general case of the other serotypes of B. thuringiensis. In contrast with these serotypes, B. thuringiensis var. israelensis is not pathogenic to the tested larvae of Lepidoptera.
苏云金芽孢杆菌以色列变种对埃及伊蚊和斯氏按蚊杀幼虫作用的比较研究表明，埃及伊蚊更为敏感，在高剂量下30至40分钟内死亡率达100%。但是，对于这两种蚊子而言，这些细菌的毒性都非常高，死亡率回归曲线和半数致死浓度（LC50）都表明了这一点。这种毒性与晶体有关，并且像苏云金芽孢杆菌其他血清型的一般情况一样，可以通过稀碱溶液从晶体中提取出来。与这些血清型不同，苏云金芽孢杆菌以色列变种对所测试的鳞翅目幼虫无致病性。
