2006～2009年首都机场口岸蜚蠊密度监测报告

Monitoring of Cockroach Density in Beijing Capital International Airport,2006～2009

[目的]掌握首都机场口岸蜚蠊密度、季节消长和种群构成情况,为首都机场口岸的蜚蠊防治提供科学依据。[方法]统一采用粘捕法。[结果]2006、2007、2008、2009年首都机场口岸蜚蠊的年平均密度分别为0.30、0.49、0.16、0.16只/张.夜;从2008年起蜚蠊密度明显下降,下降率为62.79%;首都机场口岸目前只监测到两种蜚蠊,其中德国小蠊为优势种,占98.50%,美洲大蠊占1.50%。[结论]首都机场口岸全年均有蜚蠊孳生,没有明显的季节消长规律;种类有德国小蠊和美洲大蠊两种,其中德国小蠊为绝对优势种,应成为今后防治的重点。

Objectives To learn about the density, the population composition and seasonal fluctuation of cockroach in Beijing capital international airport and to provide the scientific basis for cockroach control. Methods Paste catching method was used in the surveillance. Results Cockroach annual average density for 2006, 2007, 2008, 2009 are 0.30, 0.49, 0.16 and 0.16/sheet · night respectively. Since 2008, the average density of Cockroach has decreased significantly by a reduction of 62.79%. There were 2 species of cockroaches, the Blattella germanica , the dominant species, accounting for 98.50%, Periplaneta americana, accounting for 1.50%. Conclusions There is Cockroach breeding perennially in the Beijing capital international airport, but no obvious seasonal fluctuation law. There exists 2 species of cockroaches , Blattella germanica and Periplaneta americana . Blattella germanica was the dominant species in Beijing capital international airport, suggesting that the emphasis should be put on the control of it in the future.
