目的掌握大连市城区蜚蠊种群密度及季节性消长动态变化规律。方法统一使用粘捕盒诱捕。结果大连市城区蜚蠊主要有德国小蠊、日本大蠊、黑胸大蠊3种,德国小蠊占97.51%;7～10月为蜚蠊孳生、活动频繁期,9月达高峰期,密度及侵害率分别为5.53只/张、25.30%。结论德国小蠊为优势种群,密度及侵害率高峰均出现于9月,应建立以综合防制为主的长效机制,达到有效控制蜚蠊孳生的目的。
Objective To grasp the dynamic changes of population density and seasonal fluctuation of cockroaches in Dalian urban area. Method unified use of catching box trapping. Results There were three cockroaches in the urban area of Dalian City, three cockroaches (Blattella germanica and Blattella germanica) and 97.51% (Blattella germanica). The breeding of cockroaches was carried out from July to October with frequent activities and peaked in September. The density And infringement rates were 5.53 / Zhang, 25.30%.
