As a suitable emergency measure to arrest epidemics of Japanese encephalitis in Korea, the ultra-low-volume method of spraying insecticide to control the mosquito vector Culex tritaeniorhynchus has been tested in 2 successive years over a 16-km (2) area, utilizing a large fixed-wing aircraft. Malathion concentrate applied at 0.36 litres/ha gave insufficient control of the parous (infective) females, and no reduction in total numbers of this species. Fenitrothion concentrate applied at 0.45 litres/ha resulted in a 77-87% reduction in total numbers and an 87-98% reduction in parous females over a 4-day period.
作为在韩国控制日本脑炎流行的一项适当应急措施，利用大型固定翼飞机，连续两年在16平方公里的区域内，对超低容量喷洒杀虫剂以控制蚊媒三带喙库蚊的方法进行了测试。以0.36升/公顷的剂量施用马拉硫磷浓缩液，对已产卵（具感染性）雌蚊的控制效果不足，且该物种总数未减少。以0.45升/公顷的剂量施用杀螟硫磷浓缩液，在4天内使该物种总数减少了77%-87%，已产卵雌蚊减少了87%-98%。
