摘要水稻黑条矮缩病毒（Sogatella furcifera (Horváth)）的频繁暴发和广泛传播加剧了中国东部水稻的产量损失。使用杀虫剂抑制病媒是预防病毒病流行的基本方法。但是，目前国内对糠螨的抗药性状况尚未进行调查。本研究评价了氟虫蜱对丁丙嗪、吡虫啉、噻虫嗪、毒死蜱和吡虫嗪的剂量反应。中国东部大多数人群对丁丙非津产生了中度耐药性（高达25倍）。约32%的田间种群对吡虫啉表现出中度抗性，而其他种群对吡虫啉的敏感性变化较小（7.6倍）。田间种群对噻虫嗪的敏感性差异较小（<6倍），无明显抗性。田间种群对毒死蜱的敏感性差异明显（10.2倍），其中8%的种群表现为中度抗性，32%表现为低水平抗性。大部分种群（72%）对吡蚜酮敏感，野外种群对吡蚜酮的敏感性差异较小。丁丙非津的频繁和广泛使用导致了丁丙非津耐药性的迅速发展，丁丙非津耐药性在中国野外种群中普遍存在。为防止耐药性进一步发展，应限制丁丙非津的使用，并与具有不同作用方式的替代杀虫剂轮流使用。
ABSTRACT Frequent outbreaks and widespread transmission of rice black-streaked dwarf virus by Sogatella furcifera (Horváth) (Hemiptera: Delphacidae) have aggravated yield losses of rice in eastern China. The use of insecticides for suppression of the vector has been a fundamental approach to prevent epidemics of the virus disease. However, the status of insecticide resistance in S. furcifera has not been examined recently in China. In this study, dose responses of S. furcifera to buprofezin, imidacloprid, thiamethoxam, chlorpyrifos and pymetrozine were evaluated. Most populations in eastern China have developed moderate resistance to buprofezin (up to 25-fold). Approximately 32% of field populations exhibited moderate resistance to imidacloprid, while other field populations showed minor changes (7.6-fold) in their susceptibility to this insecticide. Low variation of susceptibility to thiamethoxam (<6-fold) was observed among field populations, and no obvious resistance to this product was observed. Obvious variation (10.2-fold) of susceptibility to chlorpyrifos existed in field populations of which 8% displayed moderate resistance, and 32% exhibited low level resistance. Most populations (72%) were susceptible to pymetrozine, and relatively low variation of susceptibility to it was detected among the field populations of S. furcifera. Frequent and extensive use of buprofezin had driven the rapid development of resistance, and buprofezin resistance is widespread in the field populations of S. furcifera in China. To prevent further development of the resistance, use of buprofezin should be limited and rotated with alternative insecticides with different modes of action.
