什邡市地震灾后蝇类密度及种群初步调查

Preliminary investigation on the density and population of flies after earthquake in Shifang city

目的为什邡市建立病媒生物监测体系和网络,掌握地震灾后恢复重建初期该市蝇类密度动态和种群分布。方法采用笼诱法,对什邡市5个乡镇灾民安置点的帐篷、活动板房、垃圾点、厕所和医院的蝇密度进行监测和种群调查。结果捕获的蝇类有3科6种,其中大头金蝇为优势种,占捕蝇总数的56.0%。监测的5个镇中,洛水镇和蓥华镇的蝇密度较高,分别为358.0和91.7只/笼,马祖镇蝇密度最低,为13.0只/笼。结论初步摸清了什邡市地震灾后蝇密度和种群构成情况,填补了什邡市此项工作的空白,为开展蝇类防治提供了依据。

Objective To establish the monitoring system and network of the vector and know the flies density dynamics and its population distribution in the early reconstruction after earthquake in Shifang city. Methods The fly density and its population composition were monitored in tents, removable house, trash can, toilet and hospitals by cage trapping method in 5 towns in Shifang city. Results The flies caught mainly belonged to 3 species, 6 genera. Of which, Chrysomya megacephala was the dominant specie, accounting for 56.0% of the total. In monitored 5 township （town）, the density of fly was higher in Luoshui town and Yinghua town, with the density of 358.0 individuals/cage and 91.7 individuals/cage, and the density of flies in Mazu town was the lowest with the density of 13.0 individuals/cage. Conclusion This investigation primarily knew the flies density and its population composition after earthquake in Shifang and filled a gaps in this area, which could provided the basis for the prevention and control of flies.
