目的 了解台州市蜚蠊种群分布、密度状况和季节消长规律,为防制工作提供科学依据。方法 于2011-2014年,每个县(市、区)城区随机选择农贸市场1处、餐饮店2处、宾馆1处、医院1家和居民区1个,每月中旬监测1次,采用粘捕法进行蜚蠊密度监测。结果 台州市2011-2014年蜚蠊平均侵害率为10.14%,平均密度为0.33只/张,以德国小蠊为优势种;月平均密度为0.05~0.66只/张,7-9月为密度高峰期,月平均侵害率为2.03%~18.64%(χ²=670.83,P < 0.01);农贸市场平均密度及侵害率最高,医院最低。结论 5-6月为突击灭蜚蠊的最佳时机,应采取综合防制措施,对农贸市场、餐饮店等重点场所进行防制。

Objective To investigate the population density and seasonality of cockroach in Taizhou city, and providing scientific basis for prevention and control. Methods One farmer's market, two restaurants, one hotel, one hospital and one neighborhoods were randomly selected from each county (city, region). The sticky traps method was used to monitor the density of cockroaches1 time per mid month. Results Form 2011 to 2014, the average infestation rate of cockroaches was 10.14%, and the average density was 0.33. German cockroach was the predominant species in Taizhou city, monthly average density fluctuations was 0.05-0.66. There was a peak in July to September and the monthly average infestation rate fluctuated 2.03%-18.64%(χ²=670.83, P < 0.01). The average density and infestation rate of farmer's market were the highest, hospital was the lowest. Conclusion May to June is the best time to eliminate cockroaches. The key of eliminating cockroaches in urbanized area is using integrated prevention and control.
