泰安市蝇类密度监测结果分析

Monitor of fly density in Tai'an city

目的掌握泰安市蝇类种群构成、季节消长和不同生境蝇密度情况,为制定蝇类防控方案提供科学依据。方法采用笼诱法进行蝇类密度监测。结果 2010年共捕获蝇类2 054只,平均蝇密度为17.1只/笼。其中,优势蝇种主要有家蝇(25.80%)、丝光绿蝇(20.84%)和厩腐蝇(12.22%)。蝇类密度季节消长基本呈单峰曲线,7-8月形成密度高峰。不同生境蝇密度季节消长曲线不同。农贸市场蝇密度最高,达25.3只/笼。结论 2010年蝇密度水平较高,家蝇、丝光绿蝇、厩腐蝇是重点防控蝇种。建议采取综合防治措施,在蝇密度高峰期采取防蝇、灭蝇措施,减少蝇媒传染病的发生,并加强对蝇类及其传播疾病的长期监测、预警、控制措施的研究。

Objective To grasp the population composition and its seasonal fluctuation of flies in Tai＇an city,and provide the scientific basis for developing flies control programs.Methods The cage alluring was conducted to monitor the flies density.Results A total of 2 054 flies were captured,with the average flies density of 17.1 pieces per cage.Of which,the dominant species were Musca domestica（25.80%）,Lucilia sericata（20.84%） and Muscina stabulans（12.22%）.The fluctuations of the flies density followed a single-peaked curve,the peak value appearing from July to August.It was different from the seasonal fluctuations of flies density in different habitats.The flies density in farmers＇markets was very high（25.3 pieces per cage）.Conclusion The level of flies density is very high,and the main control targets are Musca domestica,Lucilia sericata and Muscina stabulans in Tai＇an city,so it is necessary to take the integrated measures to reduce the density of flies and strengthen the surveillance,warning and measures of flies and its diseases.
