摘要
目的了解张掖市城区蝇类种群密度和季节消长情况,掌握城市蝇类的分布特点及消长规律,为疾病控制提供科学依据。方法采用笼诱法。结果张掖市城区蝇密度平均为4.30只/笼,蝇种分布以家蝇为主。密度以绿化带最高,为7.96只/笼,其次为餐饮店外环境,为4.85只/笼。蝇类密度基本呈前高后低的双峰型曲线,5月和9月有两个峰值,以5月最高,达10.93只/笼。结论张掖市城区蝇类以家蝇为主,应在蝇类繁殖高峰期前采取综合防制措施,降低蝇密度,预防传染病的发生。
Objective This survey aims at grasping the density and the growth and decline of flies with seasons in urban area of Zhangye, and finding out the characteristics of distribution of the flies and their patterns of growth and decline with seasons, to provide scientific basis for their control. Methods Cage trap method. Results The density of flies in urban area of Zhangye was 4.30 flies every cage. Musca domestica is the dominant species. The density of flies in greenwood is highest, which is 7.96 flies every cage, the following is in surrounding of restaurant, which is 4.85. Two peaks of density appeared in May and September, respectively. The density is the highest in May( 10.93 flyies every cage). Conclusion Musca domestica is the dominant fly species in urban area of Zhangye with a high density from April to September. Some control measures should be taken to reduce density of flies to prevent infectious diseases.
