蝴蝶滞育研究进展

Research advance in butterfly diapause

介绍了近年来蝴蝶滞育虫态、光敏感时期、光周期和温度等环境因素对滞育的影响、滞育期间的形态结构和生理生化变化、滞育的神经内分泌调控和分子生物学等方面的研究概况。指出,目前蝴蝶滞育研究主要集中在外界环境对滞育的影响上,在生理生化和内分泌机制等方面的研究相对薄弱,而在分子生物学方面的研究报道极少。滞育的生理生化机制、神经内分泌调控、分子机制和滞育应用研究,将成为今后蝴蝶滞育研究的热点;一些观赏价值较高的蝴蝶将成为今后研究的重点。充足稳定的实验蝴蝶难以获得,是目前研究蝴蝶滞育的一个难点。蝴蝶养殖业的发展将有利于推动蝴蝶滞育研究。

Diapause is a kind of strategy of butterfly to live through the adverse conditions,and it is all instinct of butterfly coming into being in the progress of the evolvement.The recently related researches are reviewed,including the diapause stage,the sensitive stage,the effect of daylength and other environmental factors on diapause,and structural,physiological and biochemical changes in the duration of diapause.The researches mainly focus on the effects of environment on diapause,but less on physiological,biochemical and neurohomonal mechanisms,and nearly few on molecular mechanisms.These not-in-depth areas will be hot,and some high value butterfly species will be paid more attention.One of the difficulties of the study in diapause is how to get enough butte flies.So,the breeding technology on butterflies should be improved,and promote the research of diapause.
