    摘要:

    采用药膜法测定了广东、海南、福建、广西等4省(区)桔小实蝇Bactrocera dorsalis种群对敌百虫、高效氯氰菊酯、阿维菌素的抗性.结果表明,除了部分地区的种群已达到低水平的抗性外,如福州种群对阿维菌素抗性达到5.01倍,澄海、闽南桔小实蝇种群对敌百虫抗性达到4.56和4.07倍,大部分地区桔小实蝇种群对上述3种杀虫剂抗药性尚处于敏感阶段.2003~2004年监测了广州郊区桔小实蝇成虫对敌百虫、高效氯氰菊酯、阿维菌素、乐斯本、印楝素的抗药性变化,结果显示除敌百虫外,桔小实蝇对其他4种药剂抗药性变化不明显.

    Abstract:

    Resistance to three insecticides of the oriental fruit fly,Bactrocera dorsalis(Hendel),adults from Guangdong,Haihan,Fujian,Guangxi Provinces was assayed by vial residue in the laboratory.The results showed that low level of resistance of the fly population from Fujian to abamectin and population from Chenghai and Minnan to trichlorphon were revealed,but other populations tested remained susceptible to trichlorphon,alpha-cypermethrin and abamectin.In 2003 and 2004,the resistance of the fly adults from Gangzhou suburb to five insecticides was monitored by vial residue.It revealed that the resistance were not significantly different except trichlorphon in two years.Effective measures to reduce insecticide resistance selection were needed to sustain the utility of these chemicals in management of the oriental fruit flies in South China.
