苹果蠹蛾对高效氯氟氰菊酯的抗性现状、机制及治理策略

苹果蠹蛾Cydia pomonella属鳞翅目卷蛾科，是全球仁果类水果种植地区最重要的果树害虫之一，也是我国重大农业入侵物种，对全球水果生产造成严重威胁。当前主要采用高效氯氟氯氰菊酯等杀虫剂对苹果蠹蛾进行防治，杀虫剂的频繁使用导致其对高效氯氟氰菊酯产生了抗性。针对苹果蠹蛾对高效氯氟氰菊酯的抗性问题，该文综述了全球苹果蠹蛾种群对高效氯氟氰菊酯的抗性现状，指出由编码细胞色素P450（cytochrome P450，P450）、羧酸酯酶（carboxylesterase，CarE）和谷胱甘肽S-转移酶（glutathione S-transferase，GST）的解毒酶基因过表达导致代谢能力增强是其最普遍的抗性机制，提出合理的抗性治理策略，并对苹果蠹蛾的绿色防控进行展望。

Current status, mechanism, and management strategy of codling moth Cydia pomonella resistance to lambda-cyhalothrin

The codling moth, Cydia pomonella, is a major invasive pest of pome fruits, found on six continents and causing serious damage to global fruit production. Currently, the management of C. pomonella mainly relies on the application of insecticides, which has led to the development of insecticide resistance. Two major types of insecticide resistance mechanisms-metabolic resistance and target resistance-have been documented in this species. The most common resistance mechanism involves the overexpression of detoxification enzyme genes encoding cytochrome P450 monooxygenases (P450s), carboxylesterases (CarEs), and glutathione S-transferases (GSTs), which enhances the metabolic capacity of C. pomonella to break down insecticides. Given the prominent problem of C. pomonella’s resistance to lambda-cyhalothrin and the need to maximize the effectiveness of this insecticidefor controlling the pest, it is essential to develop reasonable resistance management strategies based on comprehensive understanding the resistance mechanisms. This review summarized the current status of C. pomonella resistance to lambda-cyhalothrin, explores the underlying resistance mechanisms, and discusses strategies for effective insecticide resistance management in C. pomonella.
