摘  要:
白僵菌Bb2菌株菌丝生长和孢子萌发最适温度为25~30℃,最适pH值为5.0~6.0。孢子萌发最佳碳源为麦芽糖,最佳氮源为蛋白胨。测定结果表明,Bb2菌株对两种小麦蚜虫的毒力均达80%以上。

摘  要:
The isolate of Beauveria bassiana,Bb2,was cultured at different temperature and pH.The optimum temperature for its growth and sprouting ranged from 25℃ to 30℃.The optimum pH was at pH 5.0~6.0.The optimum carbonaceous source was maltose and nitrogenous source was peptone.The bioassay showed that the isolate of Beauveria bassiana,Bb2,was strongly virulent against wheat aphids.
