摘　　要：目的掌握宁波地区蝇类种群构成及密度季节消长规律,为政府制订蝇类病媒生物防制策略提供科学依据。方法以红糖食醋为诱饵,采用笼诱法在2006-2016年每年的3-12月监测不同生境、不同种群的蝇类密度,统计分析蝇类密度及构成。结果大头金蝇、家蝇、丝光绿蝇和铜绿蝇为宁波地区的优势蝇种,4类蝇种占总捕蝇量的80.71%,每年5-10月为蝇类活跃期,总体蝇类密度峰值出现在6月,为23.67只/笼,但各年峰值期不一致,最晚出现在9月。2012年开始宁波市蝇类密度下降明显,从2013年开始家蝇密度超过大头金蝇。绿化带和居民区蝇密度季节消长趋势呈现双峰分布,峰值分别出现在7、9月和6、9月;餐饮外环境中蝇密度呈现以6月为峰值期的单峰分布,农贸市场蝇密度季节变化峰不突出,5-9月均较高。结论宁波地区蝇类密度总体呈现下降趋势,但家蝇防制效果较其他蝇类要差,应重视对蝇类防制人员的技术培训,倡导对重点生境中优势蝇种采取综合治理措施,以降低蝇类传播疾病的发生。Objective Master the population composition and seasonal abundance of the flies to provide scientificevidences for formulating vector control strategies by the government. Methods Monitoring the populations of flies fromMarch to December in 2006-2016 in different environments with brown sugar and vinegar, to analyze the density andcomposition of flies. Results Chrysomya megacephala, Musca domestica, Lucilia sericata, and L. cuprina were thepredominant species of flies in Ningbo area, which accounted for 80.71% of the total flies. The active phase of flies wasfrom May to October each year, the peak of fly density occurred in June（23.67 flies/cage）, but the peaks in different yearswere inconsistent and the latest appeared in September. The density of flies decreased obviously from 2012, density of M. domestica exceeded Chrysomya megacephala since 2013. The seasonal abundance of flies showed bimodal distributionin the green belts and residential areas, the peaks appeared in July and September, and in June and September,respectively. The density of flies in external environments associated with food processing facilities presented a unimodaldistribution with peak in June. The peak of fly populations in market places was not prominent, density was higher duringMay to September than other months. Conclusion The density of flies generally showed a decreasing trend, but thecontrol efficacy of house flies was lower than that of other flies. We should pay more attention to technical training of fliescontrol persons, and to advocate integrated management of predominant fly species in key habitats to reduce the occurrenceof flies-transmitted diseases.
