棉铃虫对化学杀虫剂的抗性现状及分子机制研究进展

棉铃虫Helicoverpa armigera是一种世界性分布的重大杂食性农业害虫，长期大量使用化学药剂防治棉铃虫导致其对不同种类杀虫剂产生了抗性。抗性分子机制的阐明有利于棉铃虫的科学防控和抗性治理。该文主要综述棉铃虫对化学杀虫剂的抗性发展现状，以及近年来棉铃虫抗药性分子机制的研究进展，包括解毒酶代谢能力增强、靶标敏感性降低和表皮穿透能力下降等方面，并就未来研究工作和棉铃虫抗性治理新技术进行了展望。

Status of resistance to chemical insecticides in cotton bollworm Helicoverpa armigera and research progresses on the molecular mechanisms

Cotton bollworm Helicoverpa armigera is a serious omnivorous agricultural pest. Long-term and widespread use of insecticides has led to development of resistance in H. armigera to a variety of insecticides. Elucidation of the molecular mechanism of resistance is conducive to the scientific control and resistance management of H. armigera. This paper reviewed the development of resistance in H. armigera to chemical insecticides, and recent research progresses on the resistance molecular mechanisms, including enhanced metabolism mediated by detoxification enzyme, decreased target-site sensitivity, and reduced cuticle penetration. Prospects for future studies and novel control technology of H. armigera were also discussed.
