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 2019年共捕获蟑螂23 578只,平均密度为0.71只/张,德国小蠊占91.47%,为优势种群;四川省全年蟑螂密度季节性近似单峰分布,在7月达到活动高峰,平均侵害率为14.59%;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的综合防治措施,科学合理地使用杀虫剂。

Objective To learn the population composition and seasonality of cockroaches in different habitats in Sichuan Province, and provide the scientific basis for the control of cockroaches.Methods Cockroaches were captured with sticky paper in the surveillance.Results A total of 23 578 cockroaches were captured in 2019 with the average density of 0.71 insects per sheet, and the dominant species was Blattella germanica accounting for 91.47%. The density seasonality of cockroaches showed an approximately unimodal distribution, with a peak in July.The average infestation was 14.59%.The highest cockroach density appeared in farmers' markets, followed by catering trades, residential areas, hotels and hospitals.Conclusion The population composition and seasonality of cockroaches in Sichuan Province have been understood.It is necessary to make a comprehensive way to control cockroaches, with environmental management as the basic measure and scientific application of insecticides.
