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.
