目的了解广安市城区蝇类种群密度及消长情况,为制订科学防制对策提供依据。方法采用笼诱法将诱集的成蝇用乙醚杀死后进行分类鉴定。结果全年共诱集成蝇1 368只,平均蝇密度为10.13只/笼。7月蝇密度最高,达25.07只/笼,棕尾别麻蝇和大头金蝇为主要优势蝇种。结论开展蝇类防制应以环境治理为主,并结合种群特点和密度消长规律进行科学防制。
Objective To understand the population density and the growth and decline of flies in the urban area of Guang’an and provide the basis for formulating the scientific prevention and control measures. Method Cage induction was used to induce the trapping adults to die after being killed by ether. Results A total of 1 368 adult flies were collected throughout the year, with an average fly density of 10.13 / cage. July flies the highest density, up to 25.07 / cage, brown tail flies and large flies goldflies as the dominant flies species. Conclusion The prevention of flies should be dominated by environmental management, and should be scientifically controlled according to the characteristics of population and the growth and decline of density.
