某部食堂蟑螂侵害与防治效果观察

Observation on inroads situation and control efficacy of cockroach in military dining room

目的观察部队食堂蟑螂危害程度,探索适合部队食堂蟑螂防治的有效方法。方法甲食堂使用滞留喷洒加烟雾熏杀处理,乙食堂使用滞留喷洒加杀蟑胶饵处理,按月进行灭蟑并连续3个月,在每次防治后7 d进行密度调查。结果甲单位第3次处理后7 d蟑螂密度下降率为98.6%,乙单位第2次防治后7 d蟑螂密度下降率为99.5%。结论滞留喷洒的同时加烟雾熏杀或杀蟑胶饵毒杀均能取得可靠的灭蟑效果,但滞留喷洒加杀蟑胶饵灭效更好,适于在基层部队推广应用。

Objective To observe the inroads situation of cockroach and the effective methods for control in military dining room. Methods Dining room A was treated with residual spray and thermal fog,dining room B was treated with residual spray and gel bait. Every point was treated for three times. Density of cockroaches was surveyed on the 7th day after each killing. Results The decreased rate of cockroaches density was 98.6% in dining room A at the third killing,and 99. 5% in dining room B at the second killing. Conclusion Using residual spray with thermal fog formulations, or residual spray with gel bait are effective methods for killing cockroaches, the latter is more effective than the former.
