摘 要 ：球孢白僵菌（Ｂｅａｕｗｅｒｉａｂａｓｓｉａｎａ）的６个菌株（ｂｂｓｇ８７０２、ｂｂｓｇ８７０１、ｂｂ－ｓｇ８８０１、ｂｂｄｎｕ８８０３、ｂｂｄｎ８８０４和ｂｂｄｎ８８０６）对桃蚜（Ｍｙｚｕｓｐｅｒｓｉｃａｅ）的生物测定证明，所测朱对桃蚜具有毒力。运用时间－剂量－死亡率模分析死亡率随时间和剂量的变化趋势，菌株ｂｂｓｇ８７０２对桃蚜的毒力最强，其次是ｂｂｓｇ８８０１、ｂｂｄｎ８８０６、ｂｂｄｎ８８０４

Abstract:Virulence of six aphid-derived isolates of Beauveria bassiana against the green peach aphid, Myzus persicae was bioassayed in the laboratory. All the isolates tested were capable of infecting M. persicae. A time-dose-mortality model (or complementary log-
