目的：调查本省城市蜚蠊优势种德国小蠊的季节消长和夜间活动规律，研究气象因素与该蠊季节消长的关系。方法：选择城区内有蜚蠊侵害的不同生境场所，采用捕蟑盒诱捕法及目测法调查，使用关联分析方法统计分析。结果：本省德国小蠊活动高峰为每年的５月前后和９月前后，气象因素中湿度的关联系数最大（Ｒ＝０．７３２３）；其夜间活动从２１时至凌晨６时，２３时和３时有两个活动高峰。结论：该蠊全年活动，没有蛰伏期，季节消长呈双峰规律，湿度是主要影响因素；其夜间活动也呈双峰规律。防制的最佳时期为每年冬季和６、７月份，最佳用药时间为晚８时前。
OBJECTIVE: To investigate the seasonal dynamics and nocturnal activity of Blattella germanica, a dominant species of cockroach in the province, and to study the relationship between the meteorological factors and the seasonal fluctuation of the cockroaches. Methods: Different habitats of cockroaches in urban area were selected and investigated by trapping cockroach box and visual inspection method. Statistical analysis was made by using correlation analysis method. Results: The peak of activity of German cockroach in this province was the maximum (R = 0.7323) in the meteorological factors before and after May and before and after September each year. The nighttime activities ranged from 21:00 to 6:00, 23:00 and 3 When there are two peak activity. CONCLUSION: The cockroach is active throughout the year with no dormant period. Seasonal fluctuation has a bimodal pattern with humidity as the main influencing factor. Its nighttime activity also shows a bimodal pattern. The best time to control the annual winter and June, July, the best medication time is before 8 pm.
