目的 :通过对蜚蠊种群、栖息生境和不同场所不同灭蟑方法灭效的调查研究 ,探讨铁路特等客运站的蜚蠊防制对策。方法 :采用以环境防制为主 ,加强监测、分类实施、重点防制等综合防制措施。结果 :措施实施后2年各场所与实施前相比 ,蜚蠊成、若虫密度分别降低 77.99%～ 90 .2 6 %和 77.48%～ 98.2 4% ,卵鞘密度分别降低85 .0 0 %～ 10 0 %和 10 0 % ;不同场所一次用药后 3、7、15、30d蜚蠊成、若虫密度分别降低 6 6 .6 7%～ 88.89%、74.11%～ 88.0 0 %、70 .0 0 %～ 79.0 7%和 70 .5 9%～ 75 .71% ;重点部位蜚蠊成、若虫密度从实施前平均密度的 2 .38～ 2 .93倍 ,分别降为 1.16～ 1.30倍和 0 .38～ 1.18倍 ;而且减少了用药量 ,降低了灭蟑经费。结论 :有效地控制了蜚蠊滋生繁殖 ,产生了一定的社会经济效益
OBJECTIVE: To investigate the control strategy of cockroaches in Railway Passenger Stations through the investigation on the cockroach population, habitats and the different methods of killing cockroaches in different places. Methods: Adopting environmental prevention as the main control method, and strengthening the monitoring, classification and implementation, and key prevention and control measures. Results: The density of adult and nymphs decreased by 77.99% -90.26% and 77.48% -98.2 4%, and egg density decreased by 85.0% ~ 10 0% and 10 0%. The cockroach density and nymph density decreased 6 6 .67% ~ 88.89%, 74.11% ~ 88.0 0% and 70.0% respectively at 3, 7, ~ 79.0 7% and 70.59% ~ 75.71%, respectively. The density of cockroaches and nymphs at key sites was 2.38 ~ 2.93 times of the average density before implementation, which were reduced to 1.16 ~ 1.30 times and 0.38% ~ 1.18 times; but also reduce the dosage, reducing the expense of cockroaches. Conclusion: Effective control over the breeding of cockroaches has produced some socio-economic benefits
