草蛉滞育的研究进展

Research Advances in Diapause of Green Lacewings(Neuroptera: Chrysopidae)

草蛉是多种农林害虫的重要捕食性天敌昆虫,在生物防治中具有重要作用。滞育是昆虫应对不利环境条件时,生长发育停滞的一种生理状态,许多草蛉种类存在滞育现象。深入开展草蛉滞育的研究,不仅有助于明确其滞育特征和内在调控机制,也有助于提高草蛉的生物防治效果,促进草蛉的商业化生产和应用。本文归纳总结了1910年以来国内外草蛉科种类的滞育研究文献,介绍了目前已开展滞育研究的草蛉种类及其滞育特征,分析了影响草蛉滞育调控的环境因子,论述了草蛉滞育期间的形态和生理生化变化、分子机制及其滞育后发育生物学,并就滞育在草蛉规模化生产中的应用以及目前草蛉滞育研究中存在的问题进行了讨论,以期为深入草蛉滞育的基础理论研究和促进草蛉的规模化生产应用等提供参考依据。

The green lacewings are important predatory natural enemies of a variety of small,soft-bodied pests in agro-ecological systems and forests.Many species of green lacewings enter diapause in response to adverse environmental conditions.Diapause research of the green lacewings is essential for understanding characteristics and regulation mechanisms of diapause and for enhancing the biocontrol potential,thus promoting the commercial production and application of green lacewings.In this review,we summarized the literatures of diapause in the chrysopids since 1910,which included the diapause characteristics,environmental factors responsible for diapause regulation,the behavioral and physiological changes during diapause,the molecular mechanisms of diapause,and the biology of post-diapause development.The application of diapause in the mass rearing of chrysopids and research prospectives were discussed.This review serves to further the studies of diapause of chrysopids and to facilitate large-scale production and application of chrysopids in biological control.
