超市蜚蠊综合防治效果研究

Effects of integrated cockroach control in supermarkets

目的评价综合防治措施对超市蜚蠊的防治效果。方法选择3家超市,其中2家作为试验场所,1家作为对照。试验场所采取环境治理为主,化学防治为辅的综合防治措施;以相对密度下降率为指标评价防治效果。结果超市蜚蠊种类均为德国小蠊;主要侵害生鲜区、熟食区、库房、面包房、食品区和蔬果区等,百货区密度较低;采取综合防治措施3d后蜚蠊密度明显下降,超市A及超市B密度下降率分别为89.96%和81.38%;3周后密度下降率分别为93.89%和90.21%;2个月后密度下降率分别为95.05%和89.27%。结论超市蜚蠊侵害严重,优势种为德国小蠊;综合防治措施可快速有效地降低蜚蠊密度,并且具有较长的持效期。

Objective To evaluate the effects of integrated cockroach control in supermarket.Methods Three supermarkets,two as experimental sites and one as control,were selected for test.Integrated control measures,which comprised environmental improvement assisted by chemical control,were taken in the experimental sites.The control effects were evaluated with relative density decrease rate as the indicator.Results All the cockroaches captured in the supermarkets were Blattella germanica.Cockroaches were mainly distributed in the fresh food section,cooked food section,storehouse,bakery,food section,vegetable and fruit section,etc.,while the cockroach density in the grocery section was relatively low.The cockroach densities in the two experimental sites decreased by 89.96% and 81.38% three days after integrated control measures,by 93.89% and 90.21% three weeks after the measures,and by 95.05% and 89.27% two months after the measures.Conclusion Cockroaches invade the supermarkets seriously,with B.germanica as the dominant species.Integrated control measures can be used to quickly and effectively decrease the cockroach density in supermarket,and the control effects were durable.
