2014年四川省蟑螂密度监测结果分析

Analysis of cockroach surveillance in Sichuan Province in 2014

目的了解四川省蟑螂种群构成、季节消长和不同生境下密度情况,为制定蟑螂防控方案提供科学依据。方法采用粘捕法,统一使用粘蟑纸进行监测。结果 2014年共捕获蟑螂31 357只,平均密度为1.76只/张,德国小蠊占97.59%,为主要优势种群;全年蟑螂密度高峰在6、8月份,平均侵害率为18.48%;不同生境蟑螂密度为农贸市场>餐饮业>居民区>宾馆>医院。结论已基本掌握四川省城市蟑螂种群构成及季节消长情况,建议采取以环境治理为基础,科学合理地使用杀虫剂的综合治理,有效降低蟑螂密度。

Objective To investigate the population composition and seasonal fluctuation of cockroaches in different habitats in Sichuan Province,and to provide the scientific basis for cockroach control. Methods Sticky paper was used to trap cockroaches in the surveillance. Results A total of 31 357 cockroaches were captured in 2014,with the average density of 1. 76 insects per sheet,and the dominant species was Blattella germanica（ 97. 59%）. The highest density of cockroaches appeared in June and August. The average disoperation rate was 18. 48%. The highest cockroach density appeared in farmers markets followed by catering services,residential area,hotels and hospitals.Conclusion The population composition and seasonal fluctuation of cockroaches in Sichuan Province have been basically understood. It is necessary to make a comprehensive way to control cockroaches. Environmental management and scientific measures should be taken to reduce the density of cockroaches effectively.
