豆野螟的生物防治研究进展与展望

豆野螟Maruca vitrata是豇豆等豆类作物的世界性重要害虫，常年在亚热带地区严重发生，防控难度很大。传统的化学防治方法难以对其进行长久且有效的控制，因而造成害虫抗药性增强、超范围使用化学农药等诸多不良现象，严重威胁人民群众身体健康与生态安全。而生物防治作为减少化学农药用量与残留的关键技术之一，在当前我国绿色农业高速发展期更应引起研究人员的高度重视。因此，本文围绕豆野螟生物防治的研究现状与进展，分别从昆虫性信息素、天敌昆虫资源、昆虫病原物、植物源农药等4个方面进行了概述，并深入探讨了我国豆野螟生物防治领域的研究前景与方向，为豆野螟绿色防控体系的全方位建设提供参考，助力我国绿色农业高质量发展。

Advances and prospects of biological control research of legume pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae)

Maruca vitrata, an important pest of legumes such as cowpea worldwide, seriously occurs in subtropical regions all year around and is difficult to control. Traditional chemical control methods can hardly achieve long-term and effective control of M. vitrata, resulting in increased pest resistance, excessive use of chemical pesticides, and many other adverse phenomena, which seriously threaten people''s health and ecological security. As one of the key technologies to reduce the dosage and residue of chemical pesticides, biological control should be paid more attention to in the rapid development period of green agriculture. Therefore, we summarized the current status and progress of biological control of M. vitrata from four aspects, including its sex pheromones, natural enemy resources, entomopathogens, and botanical pesticides in this paper, and discussed the future research directions of biological control of M. vitrata. It contributes to the full-scale construction of the environmentally friendly control system of M. vitrata, as well as the high-quality development of green agriculture in China.
