Abstract: A study carried out in rural areas of South Korea has revealed that farmer pesticide applications of fenitrothion, fenthion and certain other organophosphorus materials are highly toxic to mosquito larvae. The rates of application (0.3 to 0.9kg/ha), although not highly residual, are from 4 to 8 times higher than those required for Cu. tritaeniorhynchus control. The commonly used knapsack sprayer provides very thorough coverage on small (≤ 1ha) farmer plots. Application by power equipment and helicopters also provides excellent larval control. In comparison to previous years, the marked increase in pesticide usage may be a partial explanation for the much lower incidence of Japanese encephalitis in rural area. / 韓国南部の農村で行なった研究から,農民が撒布するフェニトロチオン,バイテックス及びその他の二,三の有機燐剤は蚊の幼虫に対して極めて有効であることがわかった.0.3-0.9kg/haの撒布は,残留性は大きくないけれども,コガタアカイエカの防除に必要な量の4-8倍に達する.普通に用いられている背負式噴霧機は狭い区画(1ha以下)に徹底して撒布するのに便利である.動力噴霧機やヘリコプターによる撒布もまた蚊の防除に優れた効果を示す.前年までと比較して,殺虫剤の使用量が増加したことが,農村での日本脳炎患者数の減少の1つの原因かもしれない.
