高温胁迫对寄生蜂的影响及其适应机制

Effects of high temperature stress on parasitoid wasps and their adaptation mechanisms

昆虫作为变温动物类群,极易遭受高温胁迫的影响,寄生蜂也不例外。寄生蜂是害虫生物防治领域中最常用的天敌昆虫,我国已将赤眼蜂广泛用于农林业鳞翅目害虫的防治。研究高温胁迫对寄生蜂的影响,可为全球气候变暖背景下农林害虫生物防治提供新的见解和对策。本文系统综述了高温胁迫对寄生蜂生命活动的影响以及寄生蜂响应高温胁迫的机制,并就温度升高对寄生蜂规模化繁育和应用可能出现的问题和挑战进行了展望,以期为更好地发挥寄生蜂在害虫生物防治中作用提供理论参考。

Insects,including parasitoid wasps,as a group of poikilotherm,are highly susceptible to hightemperature stress.Parasitoid wasps are the most commonly used natural enemy insects in the field of,in which Trichogramma spp.have been widely used in China for the control of lepidopteran pests in agroforestry.The study of effects of high temperature stress on parasitoid wasps can provide an important theoretical basis for biological control of agricultural and forestry pests in the context of global warming.Here we provide a systematic review on the life activities of parasitoid wasps affected by high temperature stress and the response mechanism of parasitoid wasps.Finally,we also look forward to the problems and challenges of high temperature as an ecological factor in the future large-scale rearing and application of parasitoid wasps,with a view to playing a more important role in biological control in agricultural production.
