目的了解南通市通州区蟑螂种群分布和密度,为制订蟑螂防治措施提供科学依据。方法参照《病媒生物密度监测方法-蜚蠊》(GB/T 23795-2009),采用粘捕法进行蟑螂密度监测。结果 2014年和2015年的平均粘捕率为16.10%,平均侵害率为17.43%,平均密度为0.74只/张,平均密度指数为4.61只/张。2014年粘捕率为18.12%,侵害率为18.33%,蟑螂密度为0.75只/张,平均密度指数为4.13只/张。2015年粘捕率为13.99%,侵害率为16.53%,蟑螂密度为0.73只/张,平均密度指数为5.24只/张。全年高峰期为6-8月份,9月份开始下降;蟑螂侵害率和密度最高的是农贸市场和餐饮行业。结论目前通州区蟑螂侵害水平较高,化学防治是降低其密度的首要手段,同时采取化学、环境、物理、生物相结合的综合性防治措施,以不断提高防治效果。
Objective To understand the population distribution and density of cockroach in Tongzhou District of Nantong City and provide a scientific basis for the development of cockroach prevention and control measures. Methods According to “vector density monitoring method - cockroach” (GB / T 23795-2009), the density of cockroaches was monitored by sticky catching method. Results The average sticking capture rate was 16.10% in 2014 and 2015, with an average rate of 17.43%. The average density was 0.74 per sheet and the average density index was 4.61 per sheet. In 2014, the sticky capture rate was 18.12%, the infringement rate was 18.33%, the cockroach density was 0.75 / piece, and the average density index was 4.13 pieces / piece. In 2015, the sticky capture rate was 13.99%, the infringement rate was 16.53%, the density of cockroaches was 0.73 / piece, and the average density index was 5.24 piece / piece. The annual peak is from June to August, and it begins to decline in September; the highest incidence and density of cockroaches are farmers’ markets and the catering industry. Conclusion At present, the level of cockroach infiltration in Tongzhou District is high. Chemical control is the primary means to reduce its density. At the same time, comprehensive prevention and control measures should be taken with the combination of chemical, environmental, physical and biological measures.
