摘要/Abstract

摘要： 我们从落叶松毛虫(Dendrolimus sibiricus)、印度谷斑螟(Pyralis farinali)幼虫和森林土壤中分离到产生不同形状伴孢晶体的苏芸金杆菌(Bacillus thuringiensis),对三株菌进行了形态特征的电子显微镜观察、生理生化特性的测定及营养细胞的酯酶型分析,并对几种昆虫进行了室内生物测定,表现出不同的毒力。

Abstract: Three strains of Bacillus thuringiensis were isolated from the larvae of Dendrolimus sibiricus, Pyralis farinalis and from forest soil. The parasporal crystals of the strains were examined by electronic microscopy, wich showed three kinds of form: the bipyramidal and mosaic the cuboidal and the irregular. The biochemical characters of the three strains and esterase analysis of vegetative cell were examined. The three strains showed different toxicity to the test insects.

Key words: Parasporal Crystal, Bacillus thuringiensis subsp, Kurstaki, Bacillus thuringiensis subsp, Galleriae
