| 摘 要： | 在室内研究了球孢白僵菌在不同温度和湿度条件下对甜菜夜蛾幼虫的致病力,结果表明:温度、相对湿度、幼虫龄期对白僵菌的致病力具有显著的影响,24～27℃是球孢白僵菌感染甜菜夜蛾的最适宜温度;相对湿度大于90%,甜菜夜蛾的幼虫虫龄越低,越有利于球孢白僵菌对幼虫的感染。 |
| 关 键 词： | 球孢白僵菌 甜菜夜蛾 温度 湿度 幼虫龄期 致病力 |

| Abstract: | The pathogenicity of Beauveria bassiana to Spodoptera exigua larvae at different temperature and humidity indoors was studied.The results showed that temperature,relative humidity and larval instar had significant impacts on the pathogenicity of Beauveria bassiana.The temperature range 24~27 ℃,the relative humidity more than 90% and lower larval instar were the most suitable conditions for the infection of Beauveria bassiana to Spodoptera exigua larvae. |
| Keywords: | Beauveria bassiana Spodoptera exigua Temperature Humidity Larval instar Pathogenicity |
