摘　　要：研究了不同温度、紫外线及田间常用的2种杀虫剂和3种杀菌剂对球孢白僵菌菌丝生长的影响，结果表明：在15～25℃温度范围内，球孢白僵菌的菌落直径随着温度的升高而增大，在25-12条件下达到最大，即23．2～32．0mm。经紫外线处理，得到菌株BbI01抗紫外线能力最强，处理与对照菌落直径无差别；杀菌剂对球孢白僵菌的菌丝生长完全抑制，而杀虫剂的抑制作用较弱，其中敌百虫对球孢白僵菌菌丝生长反而有促进作用，说明杀虫剂与球孢白僵菌相容性较好。This paper researched the influence of different temperatures, ultraviolet radiation, 2 pesticides, and 3 bactericide on Beauveria bassiana mycelial growth. The results showed that the B. bassiana colony diameter increased with temperature increasing at range of 15--25℃. At 25℃, the clony diameter were the biggest, from 23.2 to 32.0mm. We had fungi BbI01which had strong anti-ultraviolet radiation ability through ultraviolet treatment. There wasn＇t difference between treatment and control colony diameters. The fungicides could inhibited the mycelial growth completely. Whereas the insecticides had a slight inhibited effect on the mycelia growth and trichlorfon even accelerated the mycelia growth instead of inhibition. It showed that the insecticides were more compatible with B. bassiana.
