Abstract: Objective To determine the population distribution and seasonal dynamics of cockroaches for effective prevention and control in Lanzhou city, Gansu province, China. Methods We used glue boards to catch the Blattella (cockroaches). We selected 3 survey sites in Lanzhou city and placed the glue boards at the 15th of each month from 2006 to 2015. For each site, the investigators randomly selected two catering establishments, one farm product market, one hotel, one hospital and one residential area. All the sites were relatively fixed. The correlations between cockroach density and infestation rate were tested by one-sample Kolmogorov-Smirnov test and Bivariate Correlations. Results From 2006 to 2015, we placed 21 600 glue boards at chosen sites, and retrieved 21 126 boards, which caught 43 685 cockroaches. They were all B. germanica. The infestation rate was 13.86% and the average density was 2.07 per board. The density of farm product markets was the highest (3.28/board) and hospital was the lowest (0.26/board). The infestation rate of cockroach was positively associated with the density (r=0.892, P<0.01). Conclusion Blattella germanica was the predominant species in Lanzhou city. The population density peak was from June to October during 2006 to 2015. We should take measures to control cockroaches in April and May before the onset of the cockroach density peak.

摘要: 目的 了解兰州市蜚蠊种群构成及季节消长情况,为科学制定防制对策及控制蜚蠊危害提供依据。方法 于2006-2015年在兰州市城区选择3个调查点,每个调查点随机选择餐饮店2处、农贸市场、宾馆、医院和居民区各1处,各调查点相对固定,采用粘捕法每月中旬调查1次。对蜚蠊密度及其侵害率进行二元变量相关性分析,运用t检验和Bivariate Correlations进行统计学分析。结果 在各生境布放粘蟑纸21 600张,回收21 126张,阳性2 928张,捕获蜚蠊43 685只,均为德国小蠊,平均密度为2.07只/张,侵害率为13.86%;以农贸市场蜚蠊密度最高,达3.28只/张,医院最低,仅为0.26只/张。不同生境均受蜚蠊侵害,侵害率与密度呈正相关(相关系数r=0.892,P<0.01)。结论 德国小蠊为兰州市优势种,密度高峰期在6-10月,应在4-5月蜚蠊密度高峰期前采取杀灭措施。
