Abstract

Portable and vehicle thermal fogs were tested using etofenprox, bifenthrin, and deltamethrin diluted with diesel oil, kerosene, and water against domestic vector mosquitoes, Aedes albopictus, Anopheles sinensis s.l., Culex pipiens, and Culex tritaeniorhynchus. The female mosquitoes were confined in small cages suspended on poles at progressively greater distances from the fog release point at an open field. The average mortality rates of four vector mosquitoes to the three insecticides were 52.0% and 64.0% at a portable thermal fogs diluted with diesel oil and water within a 10 m distance, respectively. A vehicle thermal fog had a mean mortality of 34.8% of the females to the insecticides diluted with diesel oil within 50 m. The mortality rates were not significantly different among all the tested distances. At a dilution solvent test, the mortality of the females to the insecticides diluted with kerosene was 1.9 times higher than that of diesel oil.

국내 감염병 매개 모기인 흰줄숲모기(Aedes albopictus), 중국얼룩날개모기(Anopheles sinensis s.l.), 빨간집모기(Culex pipens), 작은빨간집모기(Cx. tritaeniorhynchus)를 대상으로 살충제 deltamethrin, etofenprox, bifenthrin를 석유, 등유, 그리고 물로 희석하여 휴대용 가열연막과 차량용 가열연막의 방제효과를 측정하였다. 실험은 야외에서 일정한 거리에 암컷모기가 들어있는 노출장을 매단 스탠드를 세우고 실시하였다. 세 종류의 살충제를 각각 경유에 희석하여 살포한 휴대용 가열연막은 10 m 이내의 모기에 대해 평균 52.0%의 치사율을 보였고, 살충제를 물로 희석하여 사용한 휴대용 가열연막의 모기 치사율은 평균 64.0%였다. 살충제를 경유로 희석한 차량용 가열연막은 모기에 대해 살포 거리 50 m 이내에서 평균 34.8%의 치사율을 보였다. 가열연막용 살충제의 희석제로 사용되는 경유와 등유의 모기 치사효과는 등유가 경유에 비해 1.9배 높게 나타났다.
