山东省居民区蟑螂监测研究

Monitoring of cockroaches in residential areas of Shandong Province

目的了解山东省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,为蟑螂防治工作提供依据。方法采用粘捕法捕捉蟑螂。结果 2005-2010年共粘捕蟑螂2 045只,经鉴定分别为德国小蠊、日本大蠊、黑胸大蠊3种。蟑螂总平均密度为0.69只/张,其中2007年蟑螂密度最高为2.27只/张;2008年蟑螂密度最低为0.58%;优势种群为德国小蠊,占蟑螂总数的96.38%。总平均侵害率为11.53%,其中2007年蟑螂侵害率最高,为28.72%。结论应用监测数据进行综合防治可有效降低蟑螂密度,更好控制蟑螂繁殖,减少蟑螂对居民生活环境侵害风险的发生。

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. Methods The adhesion method was used to capture the cockroaches. Results During 2005-2010,2 045 cockroaches were captured,and identified as Blattella germanica,Periplaneta japonica and P. fuliginosa. The total average density of cockroaches was 0. 69 pieces per sheet. The highest density was 2. 27 pieces per sheet,appeared in 2007; the lowest was 0. 58% in 2008. The dominant species was Blattella germanica,accounting for 96. 38% of the total number of cockroaches. The total average infestation rate was 11. 53%,the highest was 28. 72% in 2007. Conclusion Application of the comprehensive prevention and control method can effectively decrease the density of cockroaches,and reduce the risks for the infestation of cockroaches to the living environment of the residents.
