2010—2015年山东省居民区蟑螂监测分析

Analysis on monitoring of cockroaches in residential areas in Shandong Province from 2010 to 2015

目的了解山东省2010—2015年城市居民区蟑螂种类、密度、侵害率、分布特点、生态习性、季节消长趋势等变化规律,为蟑螂防治和爱国卫生工作提供依据。方法采用粘捕法捕捉蟑螂。结果 2010—2015年共粘捕蟑螂2 650只,经鉴定分别为德国小蠊、日本大蠊、黑胸大蠊、美洲大蠊4种。蟑螂总平均密度为0.86只/张,其中2012年蟑螂密度最高,为1.40只/张;2011年蟑螂密度最低,为0.57%;总平均侵害率为14.40%,其中2012年蟑螂侵害率最高,为22.50%。结论山东省城市居民区蟑螂密度监测为有效控制蟑螂繁殖,降低蟑螂对居民区大环境侵害,完善蟑螂防治和防控工作提供了有效的数据支持。

Objective To understand the changes of cockroach species,density,infestation rate,distribution characteristics,ecological habits and seasonal variations in the urban residential areas of Shandong Province from 2010 to 2015,and provide the basis for the prevention and control of cockroaches.Methods The adhesion method was used to capture the cockroaches.Results From 2010 to 2015,totally 2 650 cockroaches were captured,and identified as Blattella germanica,Periplaneta japonica,periplaneta fuliginosa and Periplaneta americana.The total average density of cockroaches was 0.86 insects per sheet,the highest was 1.40 insects per sheet in 2012,and the lowest was 0.57% in 2011.The total average infestation rate was 14.40%,the highest was 22.50% in 2012.Conclusion The monitoring on cockroach density in the urban residential areas of Shandong Province can provide effective support for effective control of cockroaches.
