摘要
目的：观察不同方法灭蟑效果，找到灭蟑适宜途径。方法四家餐馆，甲使用雾化喷洒法，乙使用灭蟑胶饵处理，丙先雾化喷洒再用灭蟑胶饵处理，丁停止只用灭蟑胶饵。结果甲饭店蟑螂密度降低99．6％，两个月后基本恢复到以前密度；乙饭店蟑螂密度降低不明显；丙饭店密度降低99．4％，两个月后蟑螂密度未反弹；丁饭店两个月后蟑螂密度升高到34．2只/张。结论药物喷洒可迅速杀灭大部分蟑螂，短时间内将蟑螂灭度降低，胶饵布放在蟑螂密度较低时能够长期控制蟑螂密度。
Abstract
Objective To observe the effects of different methods of cockroach killing effect,to find suitable ways of cockroach killing.Methods The four restau-rants,the first using a spray method;the second using gel bait against cockroaches processing;the third using the spray first,and gel bait against cockroaches processing;the fourth stop using gel bait against cockroaches .Results The first restaurant cockroach density decreased by 99 .6% after the atomized spray ,Two months after return to previous density;the second cockroach density decreased just a lit;the third cockroach density decreased 99.4%,two months after the cockroach density did not re-bound;the forth cockroach density increased to 34.2 one pieces.Conclusion Drug spray can quickly kill most cockroaches,a short period of time will reduce cockroach gel bait,cloth on cockroach density is low for long-term control of cockroach density.
