环境因子对蝙蝠蛾成虫生殖行为的影响

Effect of Environmental Factors on the Reproductive Behavior of Ghost Moth Adults

冬虫夏草人工培育的关键因素之一在于获得大量虫源,为提高雌虫产卵量,分析了环境空间、环境湿度、去雄处理、添加寄主植物及光照处理等5个因子对蝙蝠蛾雌虫产卵和产卵率的影响。结果表明:采用纵向空间、增加湿度、添加寄主植物或黑暗处理可提高有效卵数量;增加湿度或寄主植物可有效提高蝙蝠蛾成虫的产卵率,达(84.81±1.81)%和(94.54±1.83)%,增加寄主植物可以有效降低余腹卵数量;弱光处理不利于成虫产卵。表明良好的湿度、添加寄主植物或黑暗处理有利于蝙蝠蛾成虫的生殖活动,可有效提高成虫产卵量,为获得大量虫源提供保障。

One of the key factors in artificial cultivation of Cordyceps sinensis is to obtain a large number of insect source.In order to improve the fecundity of female insects,the effect of environmental space,environmental humidity,emasculation,addition of host plant and light treatment on the fecundity and oviposition rate of female ghost moth were analyzed.The results showed that the number of effective eggs could be increased by longitudinal space,increasing humidity,adding host plants or darkness treatment,and the oviposition rate of adult ghost moth could be increased to(84.81±1.81)%and(94.54±1.83)%by increasing humidity or host plants.The addition of host plants could effectively reduce the number of residual eggs.Weak light treatment was not conducive to the spawning of adults.In summary,suitable humidity,addition of host plants or dark treatment were conducive to the reproductive activities of adult ghost moth,and could effectively improve their fecundity,thus providing aguarantee for obtaining a large number of insect sources.
