背景技术背景：为了解东方实蝇（Bactrocera dorsalis（Hendel））的抗性程度，于2007 - 2008年在中国大陆13个地点采集了25个实蝇种群。结果：与敏感株相比，B. 16个种群对敌百虫表现中抗（11.5倍< RR < 25.8倍），8个种群表现低抗或敏感（1.4倍< RR < 8.9倍）。对高效氯氰菊酯，1个种群表现高抗（RR = 44.0倍），9个种群表现中抗（12.2倍< RR < 28.4倍），14个种群表现低抗或轻度抗性（3.0倍< RR < 9.7倍），1个种群保持敏感（RR = 1.1倍）。对阿维菌素，5个居群表现为高抗（44.3倍< RR < 104倍），7个居群表现为中抗（11.4倍< RR < 38.6倍），3个居群表现为低抗（3.5倍< RR < 5.6倍）。室内连续抗性筛选结果表明，桔小实蝇对敌百虫、高效氯氰菊酯和阿维菌素的抗性倍数分别为71.6倍、333倍和70.4倍。所有结果表明，应建立早期抗性管理计划，以恢复以农药为基础的控制措施的效力。(C)2010年化学工业协会
BACKGROUND: In order to investigate the extent of resistance of oriental fruit fly, Bactrocera dorsalis (Hendel), which is a widespread pest throughout tropical, subtropical and temperate fruit crops, 25 populations of this insect were collected from 13 sites in mainland China in 2007 and 2008. In addition, resistant strains were established that showed increasing development of resistance.RESULTS: Compared with the susceptible strain, one population of B. dorsalis expressed high resistance (RR = 70.4-fold), 16 populations expressed medium resistance (11.5-fold < RR < 25.8-fold) and eight populations had low resistance or remained susceptible (1.4-fold < RR < 8.9-fold) to trichlorphon. As regards beta-cypermethrin, one population showed high resistance (RR = 44.0-fold), nine populations expressed medium resistance (12.2-fold < RR < 28.4-fold), 14 populations expressed low or minor resistance (3.0-fold < RR < 9.7-fold) and one population remained susceptible (RR = 1.1-fold). As regards avermectin, five populations had developed high resistance (44.3-fold < RR < 104-fold), seven populations expressed medium resistance (11.4-fold < RR < 38.6-fold) and three populations expressed low or minor resistance (3.5-fold < RR < 5.6-fold). A continuous resistance selection in the laboratory strain showed that the resistance ratios to trichlorphon, beta-cypermethrin and avermectin were 71.6-fold, 333-fold and 70.4-fold respectively.CONCLUSION: The data provided a comprehensive survey of insecticide resistance in Bactrocera dorsalis in mainland China. All results suggested that early resistance management programmes should be established for restoring the efficacy of pesticide-based control measures. (C) 2010 Society of Chemical Industry
