Abstract: A number of isolates of Bacillus thuringiensis were obtained from 129forest soil samples at 0-5 cm depth collected from 8 Nature Reserves Chaocha, Dailing, Qiangfoshan, Laoshan,Huangshan, Zijinshan,Wuyishan,and Xishuangbanna) in China. The number of Bacillus and the rate of isolates(% )of Bacillus thuringiensis showed difference in forest soil of distinct Nature Reserves.Calculation of rate of Bacillus thuringiensis to Bacillus in these forest soils also showed difference.These differences have no correlation with soilmoisture,pH, and nurture of forest soil.The isolates of Bacillus thuringiensis were identified. The toxicities of isolates of Bacillus thuringiensis against 6 species insects were determined.
Key words: Nature Reserves, Forest soil, Bacillus, Bacillus thuringiensis
