中文摘要:

农田重金属污染是全球农业面临的重要环境问题之一。重金属经植物吸收富集，由植食性昆虫取食并积累而产生上行效应，影响天敌昆虫的生长发育、生殖能力以及行为，进而影响天敌对害虫的控制作用。本文系统总结了农田生态系统中重金属沿植食性昆虫传递对天敌昆虫的影响，分析了农田重金属污染对害虫生物防治的直接与间接影响效应，发现重金属胁迫一般会导致天敌昆虫生长发育延缓、生殖力降低、捕食量减少等，直接影响害虫生物防治效果；但也可能导致害虫毒物兴奋效应产生和抗性能力增强，间接增加害虫防治难度。根据研究现状，对重金属污染影响天敌昆虫和生物防治的未来研究方向进行了展望。

英文摘要:

Heavy metal contamination in farmland is one of the important environmental problems facing global agriculture. Heavy metals are absorbed by plants, taken in, and accumulated by herbivorous insects, then affected the growth, reproduction, and behavior of natural enemies by bottom-up effects, seriously threatening the efficiency of pest biological control. In this review, the effects of heavy metal transferring along herbivorous insects on natural enemies in farmland ecosystem were systematically summarized, and the direct and indirect effects of heavy metal pollution on pest biological control were expounded. Heavy metal generally leads to negative effects such as delayed growth and development, reduced fecundity, and reduced predation of natural enemies, which directly affects the efficiency of pest biological control. In the meaning time, heavy metal also led to the emergence of poison excitement effect and the enhancement of resistance ability of pests, indirectly increasing the difficulty of pest control. In view of the current research situation, this paper summarizes and looks forward to the deficiency of the research on the influence of heavy metal pollution on natural enemy insects and biological control, and provides reference for the study of natural enemy insects under environmental heavy metal stress and the formulation of pest biological control strategies in heavy metal polluted areas.
