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 variation of cockroach species, density, invasion rate, distribution characteristics, ecological habits and seasonal fluctuation trends in urban residential areas in Shandong Province, and provide basis for prevention and control of cockroaches. Methods Adopting sticky catching method to catch cockroaches. Results A total of 2 045 cockroaches were co-grafted between 2005 and 2010, and were identified as Blattella germanica, Japanese cockroach and black-breasted cockroach. The average density of cockroaches was 0.69 per Zhang, of which the highest density of cockroaches was 2.27 per Zhang in 2007; the lowest was 0.58% in 2008; the dominant population was Blattella Germanica, accounting for 96.38% of the total number of cockroaches. The total average infiltration rate was 11.53%, of which the highest rate of cockroaches in 2007 was 28.72%. Conclusion The application of monitoring data for comprehensive prevention and control can effectively reduce the density of cockroaches, better control cockroach breeding and reduce the risk of cockroaches to inhabitants’ living environment.
