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 understand the population distribution, density and seasonality of cockroaches in Taizhou and to provide a scientific basis for prevention and control work. Methods From 2011 to 2014, 1 city farm market, 2 food and beverage outlets, 1 hotel, 1 hospital and 1 residential area were randomly selected in each county (city and district) urban area. The monitoring was conducted once every mid-month with sticky Catching cockroach density monitoring. Results The average invasion rate of cockroaches in Taizhou was 10.14% from 2011 to 2014, with an average density of 0.33 / d, with Blattella germanica as the dominant species. The average monthly density was 0.05-0.66 per Zhang, and the peak was between July and September The monthly average aggression rate was 2.03% ~ 18.64% (χ2 = 670.83, P <0.01). The average farm density and the rate of infringement were the highest in the market and the lowest in the hospital. Conclusion From May to June, the best time for surprise attack on cockroaches should be taken comprehensive prevention and control measures to prevent and control key venues such as farmers markets, restaurants and other places.
