| 摘 要： | 绿僵菌在室内对马尾松毛虫3～4龄幼虫的毒力与白僵菌相当，其LD50＝7．95×107个／L，LT50＝6．61～13．08天（孢子数在1．0×1011～1．0×107个／L）．本文还比较了绿僵菌和白僵菌在不同温度、湿度下的分生孢子萌发率．实验结果表明，绿僵菌在防治马尾松毛虫上具有较大的开发应用价值．

| Abstract: | Metarhizium anisopliae and Beauveria bassiana had been used to control Dendrolimus punctatus inlab. The lab test showed that there were not much differences in the toxicity to 3rd-4th instar larvae of D.punctatus between M. anisopliae and B. bassiana. The LD50 of M. anisopliae was 7. 95 × 10 7spores/L, withthe LT50 for the concentration of 1. 0 × 10 11- 1. 0 × 10 7spores/L being 6. 61 ~ 13. 08 days. In addition, the comparison of the spore germination percentage had been made between M. anisopliae and B. bassiana at differenttemperature and in different humidity. The laboratory test indicated that M. anisopliae was of greater valuein controlling D. punctatus. |
