| 中文摘要: |
| 日本双棘长蠹（Sinoxylon japonicum）是危害国槐和刺槐等园林树木重要的蛀干害虫。本研究采用喷雾法，用含0.1%（体积分数）吐温-80的1.0×109分生孢子/mL的球孢白僵菌（Beauveria bassiana）和绿僵菌（Metarhizium anisopliae）悬液，分别于日本双棘长蠹生活史各阶段开始时在林间进行喷雾实验。实验结果显示，球孢白僵菌的致死效果比绿僵菌好，前者喷药效果最佳的时期为成虫越冬前期；这个时期折枝内虫体校正死亡率为94.1%，僵虫率为75.0%，相对折枝率为48.9%，相对蛀孔率为49.2%。绿僵菌防治效果最佳时期是成虫羽化期；这个时期折枝内虫体校正死亡率为79.9%，僵虫率为83.3%，相对折枝率为71.0%，相对蛀孔率为54.2%。 |
| 英文摘要: |
| Sinoxylon japonicum is serious forest borer species to Sophora japonica and Robinia pseudoacacia. In this study, the spray of Beauveria bassiana and Metarhizium anisopliae solution for the management of S. japonicum were studied under different condition. B. bassiana showed best effect at the early overwinter stage of S. japonicum, broken branches within parasites corrected mortality was 94.1%; cadaver rate was 75.0%, the relative rate of broken branches was 48.9%, respectively; the relative drilling rate was 49.2%; Whereas M. anisopliae showed best effect at the adult stage of S. japonicum, broken branches in this period the corrected mortality of 79.9%, cadaver rate was 83.3%, the relative rate of broken branches was 71.0%, relative drilling rate was 54.2 %, respectively. To summary up, B. bassiana was more powerful than M. anisopliae in control S. japonicum. |
