摘要
采用成虫浸叶生测法分别测定了福建省福州、漳州、龙岩、三明、南平、宁德等地烟粉虱田间种群对13种杀虫剂的抗性.结果表明,福建省6个烟粉虱田间种群对氯氟氰菊酯、甲氰菊酯、氯氰菊酯、溴氰菊酯、乙酰甲胺磷、毒死蜱产生了高水平抗性,抗性倍数分别达838.38-2460.52、244.64-834.29、116.02-266.35、81.75-124.18、425.18-875.56和54.53-78.43倍,对乐果产生了中等水平抗性,抗性倍数达14.16-17.66倍,对敌敌畏产生了中等偏低水平的抗性,抗性倍数达6.23-11.25倍,对灭多威的抗性水平较低,抗性倍数仅为4.07-5.66倍.漳州种群已对烟碱类杀虫剂产生了中等水平抗性,对吡虫啉、啶虫脒和噻虫嗪的抗性倍数分别达23.08、10.32和24.60倍,而其它地区烟粉虱种群对吡虫啉、啶虫脒和噻虫嗪的抗性水平较低,甚至不明显,抗性倍数分别仅为1.31-3.28、1.82-7.23和1.39-5.45倍.
Resistance to 13 inseclicides in field populations of Bemisia tabaci from six regions （Fuzhou, Zhangzhou, Longyan, Sanming, Nanping, Ningde） of Fujian Province, China was monitored by adult leaf-dipping bioassay. Compared with the susceptible SUD-S strain, all the six field populations exhibited high levels of resistance to lambda-cyhalothrin （838.38-2460. 52 fold） , fenpropathrin （244. 64-834.29 fold）, cypermethrin （116. 02-266.35 fold）, dehamethrin （81.75- 124. 18 fold）, acephate （425.18-875.56 fold） and chlorpyrifos （54.53-78.43 fold）, moderate levels of resistance to dimethoate （ 14. 16-17. 66 fold）, low to moderate levels of resistance to dichlorvos （6. 23-11.25 fold） and low levels of resistance to methomyl （4.07-5.66 fold）, respectively. Among these six field-collected populations, only Zhangzhou population had moderate resistance to imidacloprld, acetamiprid and thiamethoxam （23.08 fold, 10.32 fold and 24.60 fold, respectively）. All field strains tested displayed no resistance to abamectin.
