福建长乐辖区口岸蜚蠊本底调查

Investigation of cockroahes at Fujian Changle ports

目的了解福建长乐辖区口岸各开放码头蜚蠊的种群构成、季节消长情况,为口岸防治蜚蠊和鉴别输入性蜚蠊种类提供科学依据。方法统一采用标准诱捕盒法,每月上下旬各监测1次,连续12个月。结果 2008—2009年调查共捕获各类蜚蠊1443只,经分类鉴定隶属于2科2属4种;优势种为德国小蠊,其次是美洲大蠊;长乐辖区口岸蜚蠊年平均密度为0.23只/盒。结论长乐辖区口岸蜚蠊密度低于国家标准,但仍需进一步做好口岸蜚蠊监测工作;本次调查为今后辖区口岸蜚蠊防治工作提供切实的技术资料。

Objective To understand the population composition,seasonal growth and decline on cockroach at the opening wharfs of Fujian Changle ports,and to provide scientific basis for prevention and control.Methods Standard trap boxes method was adopted,which was taken two times between early and late ten-days once a month,lasting for twelve months.Results A total of 1 443 cockroaches were caught,and identified as 2 families,2 genus and 4 species.In which,Blattelta germanica（47.82%） and Periplaneta americana（25.85%） were the dominant species,the year average density of cockroaches was 0.23/box.Conclusion The cockroach density at Changle ports is comparative lower than the national control standard,but we still need to do surveillance on cockroach well.This investigation can provides a feasible technology material for the cockroaches surveillance at Changle wharfs in the future.
