摘　　要：对杨小舟蛾卯、幼虫、蛹和成虫4个虫态进行室内人工饲养，探讨了成虫交配和幼虫饲养2个关键因子对饲养成活率的影响，系统总结了杨小舟蛾人工饲养技术。结果表明，将蛹进行单体饲养，成虫羽化后7～10h配对，交配率可提高到70％，与羽化不久即行配对的交配率存在极显著差异；采用三角烧瓶倒置饲养法饲养幼虫，其化蛹率可提高到85％，与常规饲养法的化蛹率也存在极显著差异。This paper studied the manual-breeding in the four stages （egg, larva, pupae and imago） of Micromelalopha troglodyta （Graeser）. Synchronously, we examined the effects of mating and larva breeding on the surviving ratio of manual breeding. The results showed that copulation ratio could heighten to 70 percents after emerging, and 7 to 10 hours partnership in separatelly breeding. The ratio enhanced significantly compared with the groups matted immediately after emerging. The pupation ratio increased nearly 80 to 85 percents with inversional-trigonal-flask breeding compared with normal breeding methods.
