摘　　要：白僵菌在5、35、37及40℃温度下不能发育并形成孢子,而在10、20、25及30℃中可以发育并形成孢子,但以25℃最为适宜。在上述温度中,产孢时间依次为28、3、2、4天。因为白僵菌在35℃以下湿度中孢子不能发芽和形成菌丝,所以它不可能在哺乳动物和鸟的体内繁殖并引起寄生。ABSTRACT The entomophogenic fungus, B. bassiana could not developed and formed spores in temperatures of 5. 35. 37. and 40℃, but it was grown and sp0rulated well in 20. 25 and 30℃, the optimum temperature for mycelial growth and sporulation Was 25℃. The average time to initiate , sporulation at 20.25.30℃. was 8.2 and 4 day respectively. Since mycelial growth and sporulation of B. bassjana did not occur at temperatures above 35C, it probably will not develop in avian and mammal.
