| 中文摘要: |
| 3种稻飞虱，包括褐飞虱Nilaparvata lugens、白背飞虱Sogatella furcifera和灰飞虱Laodelphax striatellus，是危害水稻生产的重要害虫。由于杀虫剂的长期使用，3种稻飞虱已经对多种杀虫剂产生了抗性。褐飞虱的抗性演变最为迅速，尤其是对新烟碱类杀虫剂；白背飞虱和灰飞虱则整体抗性积累较缓，对多数药剂仍保持较高敏感性，但对噻嗪酮也显示出抗性风险。3种稻飞虱的抗性机制均能通过上调细胞色素P450多功能氧化酶（CYP450）、谷胱甘肽S-转移酶（GST）等代谢酶的表达来增强解毒能力。总体来看，褐飞虱的抗性主要依赖代谢机制，尤其是细胞色素P450等解毒酶系统的显著上调，同时伴随部分靶标位点的适应性突变，并与水稻抗性品种形成协同适应演化；白背飞虱的抗性则以靶标机制为主，靶蛋白突变频繁出现，代谢机制也参与其中。相比之下，灰飞虱整体抗性水平较低，抗性机制以靶标变化为主，解毒酶参与程度有限，抗性发展速度缓慢。三者在抗性相关基因表达调控、共生菌调节及适应性代谢调节等方面亦呈现出不同特点。本文综述了当前3种稻飞虱抗药性的发生发展、主要抗性机制及其研究进展，并提出了基于分子机制的抗性管理策略，为科学防控和可持续治理提供理论支持。 |
| 英文摘要: |
| The three rice planthoppers, including Nilaparvata lugens, Sogatella furcifera, and Laodelphax striatellus, represented significant agricultural pests that affected rice production. Extended insecticide application resulted in these three species developing resistance to multiple chemical compounds. Among these species, N. lugens demonstrated the most accelerated resistance evolution, especially against neonicotinoid insecticides; S. furcifera and L. striatellus developed resistance more gradually and generally maintained high susceptibility to most insecticides, though increasing resistance to buprofezin presented an emerging concern. These species enhanced their detoxification capabilities through the upregulation of metabolic enzymes, including cytochrome P450 monooxygenase (CYP450) and glutathione S-transferase (GST). The resistance in N. lugens primarily stemmed from metabolic mechanisms, particularly the enhanced expression of detoxification enzymes such as CYP450, coupled with adaptive target-site mutations and co-evolution with resistant rice varieties. For S. furcifera, resistance predominantly related to target-site mutations, with frequent mutations in target proteins, while metabolic mechanisms also contributed significantly. In contrast, L. striatellus exhibited comparatively lower resistance levels, with target-site modifications serving as the primary mechanism and limited involvement of detoxification enzymes, which resulted in slower resistance development. These species also displayed distinctive characteristics regarding resistance-related gene regulation, symbiont bacteria interactions, and adaptive metabolic responses. This review synthesizes current knowledge of resistance development, fundamental molecular mechanisms, and recent research advances in these rice planthoppers, while proposing molecular-based resistance management approaches to facilitate effective and sustainable pest control. |
