摘要： 选用在我国分布较广、出现频率较高的4个血清型中的6株供试菌株，以玉米螟为毒力指示昆虫，进行了毒为指示昆虫与棉铃虫、粘虫和黄地老虎的毒力相关性测定。结果显示，设定各供试菌株对玉米螟的毒力指数为1,那么各供试菌株对棉铃虫的相对毒力指数为0.647±0.074,对粘虫的相对毒力指数为0.268±0.07,对黄地老虎的相对毒力指数为0.145±0.031.4种供试昆虫对各种供试菌株的相对敏感性顺序为玉米螟>棉铃虫>粘虫>黄地老虎。

Abstract: The toxicities of six strains of Bacillus thuringiensis (belonging to four serotypes) to Ostrinia furnacalis (toxic indicator insect) and Heliothis armigera HÜbner,Mythimna separata Walker and Euxoa segetum SchiffermÜller were tested and compared, and the correlation between the toxic indicator insect and the other three kinds of insect was also determined. Suppose the toxic index of the tested strains to O. furnacalis is 0.The toxic indices to H. Armigera, M. separata and E. segetum are 0.647±0.074, 0.268±0.070 and 0.145±0.031, respectively. So the sequence of B. thuringiensis is O. furnacalis>H. armigera>M. separata>E. segtum.
