| 中文摘要: |
| 莱氏野村菌对棉铃虫幼虫致病力以及田间控制作用的初步研究结果表明，该菌对棉铃虫幼虫有较强的致病力，致病适温２４～２７℃。田间喷施其孢子液，６ｄ后棉铃虫被寄生率平均达２２６％。 |
| 英文摘要: |
| Infectivity and control of Nomuraea rileyi to Heicoverpa armigera in the fields were studied. Bioassay and spraying the spores in the field showed that the infectivity of N. rileyi to H. armigera was high. LC50 and LT50 to the larvae were different in different instars. From 24 ℃ to 27 ℃ N. rileyi could infect H. armigera easily. The infected average rate of the larvae reached 22.6% at 6 days after the spores were sprayed in the fields. |
