中国草蛉科天敌昆虫及其生防应用研究进展

The natural enemy species of Chrysopidae from China and their applications in biological control:a review

草蛉是一类重要的捕食性天敌昆虫,在蚜虫、介壳虫、粉虱、蓟马和螨类等农业害虫的生物防治中发挥着积极作用。虽然利用草蛉进行生物防治在我国已有近50年的历史,但针对不同农业生态系统及不同害虫物种,有关草蛉优势天敌物种的精准开发利用仍受到分类鉴定、生物学习性和捕食潜能等基础科学问题研究不足的制约。本文总结了草蛉科的基础生物学习性、地区优势物种与栖境选择、捕食潜能、草蛉与猎物及植物的互作关系和田间应用现状,提出了改善草蛉生防应用成效中的关键问题,对我国具有生防应用前景的草蛉种质资源发掘进行了评述,以期为推动我国草蛉天敌物种的发掘及其在生物防治中的应用提供参考。

Chrysopidae(green lacewings)comprises a number of species that are considered to be important biological control agents and play a positive role in the biological control of aphids,coccids,thrips,whiteflies,and mites.Although green lacewings have been applied in biological control for nearly 50 years in China,the accurate development and utilization of dominant natural enemy species of Chrysopidae are restricted by insufficient researches in species identification,basic biological habits,and potential of predation for different agricultural ecosystems and pest species.Here,aiming to promote the exploitation of natural enemy species of Chrysopidae from China and their applications in pest management,we present a review of the present knowledge on their living habits,regional dominant species and their choices of habitats,potential ability as predators,interactions with prey and plants and applications in China.Key issues for improving biocontrol application effect are proposed,and comments on exploration of natural enemy species of Chrysopidae with a prospect of biocontrol are also outlined.
