小金蝠蛾是冬虫夏草菌的优良寄主之一,人工培育成虫能否正常交尾及产卵直接关系到种源的持续利用,是目前冬虫夏草人工培育产业的制约因子之一。本文通过对人工饲养小金蝠蛾两个世代(R1、R2)成虫的形态、羽化、交尾、产卵、寿命等生物学特征与其野生亲本进行比较,研究人工培育条件下小金蝠蛾成虫的交尾、产卵能力,为人工培育种源及种群的可持续利用提供依据。研究结果表明,人工饲养条件下小金蝠蛾成虫的平均体长、体重、含卵量、产卵量、寿命均为野生亲本>R1>R2,但在羽化、交尾、产卵等行为上野生亲本与R1、R2不存在明显差异;人工饲养两个世代幼虫的种群增长率分别为177.27%和117.56%,表明人工饲养条件下小金蝠蛾种群可实现持续利用。
Small gold moth is one of the excellent host Cordyceps sinensis, artificial breeding of adults can be normal mating and spawning directly related to the continued use of provenances, Cordyceps sinensis artificial breeding industry is one of the constraints. In this paper, the morphological, eclosion, mating, oviposition and longevity of two generations of Artemisia capitatum (R1, R2) were compared with their wild counterparts to study the mating, Spawning ability, provide the basis for the artificial breeding of provenance and the sustainable use of the population. The results showed that the average body length, body weight, egg count, fecundity and longevity of the adults were all relatives of wild relatives> R1> R2 under artificial feeding conditions. However, during the feathering, mating and spawning activities, There was no significant difference between R1 and R2. The population growth rates of two generations of larvae were 177.27% and 117.56%, respectively, which indicated that the population of P. miltiorrhiza could be continuously used under artificial feeding conditions.
