Abstract:

Objective To observe the efficacy of 2% deltamethrin insect-resistant mat against cockroach in the lab and field. Methods Carrying on with the method of GB/T 13917.1-2009 to observe the efficacy of 2% deltamethrin insect- resistant mat against cockroach in the laboratory and conducting an experiment against cockroach in a major hospital ward in Nanjing. Results The laboratory test showed that KT50 of insect-resistant mat was 13.4 min against Periplaneta americana and 9.6 min against Blattella germanica. The mortality was 100% after 72 h. No large numbers of dead cockroach appeared after 1 d, 3 d and 7 d. After 30 d, the declining rate of density was 43.1%, 68.5% after 60 d. Conclusion The 2% deltamethrin insect-resistant mat has better effects on killing cockroach in the laboratory. Short term efficacy against cockroach was not obvious, but it can be used with the quick killing insects against cockroach in hospital.

摘要:

目的 观察2%溴氰菊酯防虫垫对蜚蠊的防治效果。方法 依照GB/T 13917.1-2009,观察2%溴氰菊酯防虫垫的实验室灭蠊效果,选取南京市某三甲医院的某个病区观察现场灭蠊效果。结果 防虫垫实验室药效实验中,室温存放2年的2%溴氰菊酯防虫垫对美洲大蠊的半数致死时间(KT50)为13.4 min,对德国小蠊的KT50为9.6 min,72 h死亡率为100%。现场实验,施放1、3、7 d均只出现少量蜚蠊死亡,30 d后蜚蠊密度下降率为43.1%,60 d后密度下降率为68.5%。结论 2%溴氰菊酯防虫垫实验室存放2年对两种蜚蠊仍有较好的杀灭效果,现场杀灭德国小蠊,短期效果不明显,与快速灭蠊药剂配合使用可作为医院长效灭蠊产品。
