大型超市鼠害综合防治及效果评价

目的通过对大型超市鼠害原因的调查与分析,总结大型超市鼠害综合防治的措施。方法采用拖食法、夹日法调查鼠类的喜食性、密度及种群分布,粉迹法观察灭鼠效果。结果大型超市的鼠类以褐家鼠为优势种;鼠的喜食性以苹果为最佳;采取综合防治措施前鼠迹阳性率为36.51%;采取综合防治措施3个月后鼠迹阳性率降为0,灭鼠率达100%。此后连续3个月调查均未发现阳性粉块。结论综合防制鼠害效果明显。

Integrated rodent control for large supermarkets and effect evaluation

Objective To summarize the integrated rodent control measures in large-scale supermarkets by investigation and analysis of the cause of rodent damage therein.Methods The bait and trap methods were employed to capture rats for analysis of rodent palatability,density and population distribution.The powder trace method was used to evaluate the deratization effect.Results Rattus norvegicus was the predominant rodent species in large-scale supermarkets;apples were most palatable to the rats.The positive rate of rodent traces was 36.51% before the implementation of integrated control measures,and dropped to 0 after three months of rodent control,with a deratization effect of 100%.No rodent trace blocks were found in the following three consecutive months.Conclusion The integrated control measures were effective in rodent control.
