摘 要: | [目的]探讨白僵菌(Beauveria bassiana)对烟蚜的致病性。[方法]以4株球孢白僵菌(B-1、B-2、B-3和B-4)为供试菌株,测定其对烟草蚜虫的致病性。[结果]受测的4株白僵菌菌株对烟草蚜虫均有不同程度的杀虫效果。其中,B-3处理烟草蚜虫的校正死亡率达到95%以上,B-1、B-2菌株的分生孢子处理烟草蚜虫的校正死亡率超过80%,其菌丝对蚜虫也有较高的致病率;4株菌株的代谢产物对烟草蚜虫均有较强的触杀作用,施用48 h后其烟草蚜虫的校正死亡率均超过85%。[结论]为烟草蚜虫的微生物防治研究提供了参考。

Abstract: | [Objective] The aim was to explore the pathogenicity of Beauveria bassiana on tobacco aphid.[Method] The pathogenicity of four Beauveria bassiana(B-1,B-2,B-3 and B-4)strains on the tobacco budworm was studied.[Result] Different tested Beauveria bassiana strains had different levels of insecticidal effect on tobacco aphids.The corrected mortality of tobacco budworm treated by B-3 was more than 95%;the mortality rates of conidia of B-1 and B-2 strains against tobacco aphid were over 80%,and their hyphae also caused higher morbidity against tobacco aphid;metabolites of different strains of had a strong contact action against tobacco budworm,and all the mortality rates of metabolites of different strains against tobacco aphid were over 85% after 48 h treatment.[Conclusion] The research provides reference for further study on microbial control of tobacco aphid. |
