摘  要:
为探明环链棒束孢菌株XS-1对小菜蛾的防治效果,为其在生物防治方面的应用提供参考,以小菜蛾3~4龄幼虫为试虫,采用喷雾法和饲喂法研究环链棒束孢菌株XS-1发酵液和菌丝提取物对小菜蛾幼虫的致死作用。结果表明:用该菌株的PDA发酵液喷雾小菜蛾幼虫,其防治效果最明显,幼虫校正死亡率为57.14%;其次是该菌株的菌丝醇提取物喷雾处理,其幼虫校正死亡率为47.37%。结论:环链棒束孢菌株的PDA发酵液与菌丝无水乙醇提取物对小菜蛾幼虫均有防治作用。

摘  要:
P. xylostella larvae with 3-4 instar were sprayed and fed with fermentation broth and mycelia extract of Isaria cateniannulata XS-1 strain respectively to study the biological control effect of Isaria cateniannulata XS-1 strain on Plutella xylostella larvae and to provide a reference for its application in biological control. The results showed that the corrected mortality of Plutella xylostella larvae sprayed with PDA fermentation broth and mycelia extract was 57. 14 % and 47. 37 % separately. In conclusion,the PDA fermentation broth and mycelia extract from Isaria cateniannulata XS-1 strain both have the control effect to P. xylostella larvae.
