目的了解东阳市城区蜚蠊种群组成、分布、季节消长及其侵害情况,为蜚蠊的防制提供科学依据。方法采用粘蟑纸粘捕法进行监测。结果东阳市城区共发现蜚蠊3种,隶属2科2属,德国小蠊为优势种群,2007年1月至2008年12月共布放粘蟑纸3000张,捕获蜚蠊977只,阳性蜚蠊张数为391张,侵害率为0～31.2%,不同行业蜚蠊侵害率差异有统计学意义(χ2=213.61,P<0.01)。6-11月为蜚蠊密度高峰期,季节消长曲线呈单峰型,7-9月侵害率最高,不同月份蜚蠊侵害率差异有统计学意义(χ2=153.01,P<0.01)。结论东阳市城区蜚蠊孳生场所主要是农贸市场、医院和饮食行业,近年来侵害范围不断扩大,逐渐向医院和居民住宅蔓延,应采取有效措施加以控制。
Objective To understand the population composition, distribution, seasonal fluctuation and invasion of cockroaches in Dongyang City, and to provide a scientific basis for the prevention and control of cockroaches. Methods sticky cockroaches sticky catching method for monitoring. Results Three species of cockroach were found in Dongyang city, belonging to 2 genera and 2 genera. German cockroach was the dominant species. Between January 2007 and December 2008, a total of 3000 sticky cockroach papers were collected, 977 cockroaches and 9 cockroaches The number of sheets was 391 and the infringement rate was 0-31.2%. There was significant difference in the incidence of cockroaches in different industries (χ2 = 213.61, P <0.01). The peak value of cockroach density was from June to November, and the seasonal fluctuation curve showed a single peak, with the highest from July to September. There was significant difference in the incidence of cockroach in different months (χ2 = 153.01, P <0.01). Conclusion The breeding grounds for cockroaches in Dongyang City are mainly farmers’ markets, hospitals and catering industries.
