应用白僵菌防治松毛虫的试验研究中,从白僵菌的生物学特性以及从生态学角度,提出了感染途径的不同见解,但从形态学方面的探讨,尚少报导。本课题着重从形态学方面,观察白僵菌侵入松毛虫后的病变情况,分析其感病途径及致死原因;观察放菌区未死老熟幼虫及成虫生殖系统是否感菌,成虫产卵量是否降低,分析能否影响后代繁殖。
Beauveria bassiana was applied to control pine caterpillars in the experimental study, from the biological characteristics of Beauveria bassiana and from ecological point of view, put forward different views on the route of infection, but the morphological aspects of the study, but little coverage. This topic focuses on morphological study of Beauveria bassiana invade the pine caterpillars lesions, analysis of the pathogeny and causes of death; observation of non-living dead larvae and adult reproductive system in the fungus area whether the bacteria, the number of adult fecundity Whether to reduce, analyze whether the impact on future generations of reproduction.
