2010-2012年青岛市蟑螂种群密度监测结果

目的掌握青岛市蟑螂种群构成季节消长和不同生境蟑螂密度情况，为制定蟑螂防控方案提供科学依据。方法和3个监测点，2010～2012年1～12月每月中旬临测一次，采用粘捕法分别在居民伟宅、餐饮、宾馆、农贸市场和医院等不同环境中进行蟑螂种群分布、密度、季爷消长情况调查。结果布放蟑螂纸数为6480张，回收6466张，捕获蟑螂5759只，平均蟑螂密度为0．89只／张。蟑螂种类主要有两种：德国小蠊和日本大蠊，其中德国小蠊为优势种。蟑螂密度高峰在8月份，为1．36只／张；农村住户平均鼠密度最高为1．24只／张。结论应充分利用季节和气候变化规律对蟑螂消K的影响，结合环境治理开展蟑螂密度控制工作。

Analysis on Results of Cockroach Density Monitoring,Qingdao City, 2010-2012

Objective To understand cockroach distribution,density and seasonal dynamics,so as to provide scientif- ic basis for its control and prevention. Methods At the three monitoring points, monitoring was carried out once a month in the mid-month during 2010-2012. The population distribution, density and seasonal fluctuation of cockroach were surveyed using night sticky trap method in residential areas,hotels,eating houses,markets and hospitals. Results A to tal of 6 /i80 pieces of glue cockroach were placed,and 6 466 pieces were reclaimed,5 759 cockroaches,were captured. The average cockroach density was 0.89 cockroaches/sheet. There were two cockroach species： Blattella germanica and Periplaneta japonica. Blattella germanica was predominant. The peak of mean cockroach density was I. 36 cockroaches/ sheet in August. The density in markets was 1.24 cockroaches/sheet,which was the highest in different condition. Con- clusion The density of cockroach should be controlledby using the seasonal and climatic changes influence on the growth and decline of cockroach and combining with environmental management.
