某住宅楼蟑螂防治效果观察

Observation on the control efficiency against cockroaches in a residential building

目的观察某部住宅楼蟑螂侵害情况和防治效果。方法采用滞留喷洒和胶饵杀灭蟑螂,用蟑螂侵害率和密度下降率评价灭蟑效果。结果蟑螂侵害率防治前为87.50%,防治后3d为12.50%(3/24),密度下降率为86.67%～100.00%,防治前后差异有统计学意义(P<0.05)。结论该住宅楼德国小蠊侵害严重,滞留喷洒结合灭蟑胶饵杀灭蟑螂效果显著。

Objective To investigate cockroach damage and control efficiency of a residential building. Methods Kill cockroach through the methods of remained spray and gel bait,and evaluate the efficacy by damage rate and density descent rate of cockroach.Results The damage rate of cockroach was 87.50% and 12.50% before and after controlling for 3 days,respectively.The density descent rate was 86.67%～100.00%,and there was no statistically significant difference before and after control（P0.05）.Conclusions The blattella gremanica damage was serious in the residential building,and the methods of remained spray and gel bait had high efficiency against cockroach.
