目的评价滞留喷洒加毒饵杀灭蟑螂的效果。方法采用粘捕法监测投药前后蟑螂密度,用蟑螂密度下降率来评价灭蟑效果。结果平均蟑螂侵害率住户由灭蟑螂前的27.9%下降为4.7%,食堂由灭蟑前的55.6%下降为6.7%,杀灭蟑螂效果较好。结论通过现场灭蟑观察,证明滞留喷洒加毒饵杀灭蟑螂效果显著,值得推广。
Objective To evaluate the effect of decontamination spraying plus bait to kill cockroaches. Methods The density of cockroaches before and after administration was monitored by stick-catching method, and the effect of cockroach-killing was evaluated by the decreasing rate of density of cockroaches. Results The average cockroach infested rate dropped from 27.9% before the cockroach dropped to 4.7%, while the canteen dropped from 55.6% before the cockroach dropped to 6.7%. The cockroach killing effect was better. Conclusion Through the observation of cockroaches on the spot, it is proved that stagnant spraying plus bait can kill cockroaches and is worth promoting.
