摘要
目的了解浙江省蝇类种群、密度及家蝇抗药性现状,为蝇类防制提供依据。方法采用笼诱法,以红糖食醋水作为诱饵,4-11月调查蝇类种群、密度;采用点滴法调查家蝇的抗药性情况。结果所捕蝇类隶属3科10属14种,大头金蝇密度最高为3.36只/笼,家蝇次之;蝇密度高峰期在5、6月和8月;调查点家蝇对拟除虫菊酯类杀虫剂抗性较高,对敌敌畏抗性较低,对三氯杀虫酯基本无抗性。结论 6月为浙江省蝇类密度最高峰,家蝇、大头金蝇为优势蝇种;家蝇现场种群对拟除虫菊酯类抗性较高,在今后的防制工作中应提倡轮换或混合用药,控制抗性的发展。
Objective To investigate the fly population and density and the insecticide resistance of Musca domestica in Zhejiang province,China,and to provide a reference for fly control.Methods The fly population and density were investigated by cage trap method with brown sugar and vinegar as baits from April to November.Topical application method was used to investigate the insecticide resistance of M.domestica.Results The trapped flies belonged to 14 species,7 genera,and 3 families.The density of Chrysomya megacephala was the highest(3.36 flies/cage),followed by M.domestica.The peak level of fly density appeared in May,June,and August.M.domestica in the monitoring sites had high resistance to pyrethroid,low resistance to dichlorvos,and little resistance to acetofenate.Conclusion Fly density reaches the peak level in June in Zhejiang province,China,and M.domestica and C.megacephala are the dominant species.The field strains of M.domestica have high resistance to pyrethroid.Insecticides should be mixed and used by turns in the future fly control to prevent the increase of insecticide resistance.
