| 摘 要： | 用几种无公害防治措施对越冬后蛴螬进行处理,测定其致病力.结果表明,尿素对蛴螬的防治有很好的效果,校正累计死亡率可达81.35%;真菌和细菌类的致病效果受温度影响较大,在低温下的效果均不明显.真菌类以布氏白僵菌的致病力最强,恒温(25℃)条件下的致病效果明显好于自然变温(平均温度为14℃)条件. |

| Abstract: | White grubs after winter were treated by socially harmless controlling technologies in different conditions. The result showed that the urea had a obvious controlling effect on it, and its adjusted accumulative mortality rates was 81.35%. The temperature had a significant influence on bacteria and fungi,the effects were not obvious at lower temperature. The Beauveria brongniartii (Bbr) had a higher virulence and the effect at steady temperature was better than at normal temperature. |
| Keywords: | white grub Beauveria brongniartii temperature |
