| Outline of Final Research Achievements |
This study aimed to analyze what factors are important for pathogens transmission, focusing on mosquito-borne diseases such as malaria, in Burkina Faso, West Africa. As a result, it has become clear that insecticide resistance as a biological factor of mosquitoes and the use of insecticides such as pesticides as a non-biological factor have come to an extremely important aspect for malaria control. Although insecticides are important for malaria control, it has been identified that there is a high need for comprehensive and continuous monitoring, including use for agricultural applications.

| Academic Significance and Societal Importance of the Research Achievements |
ブルキナファソ西部では綿花栽培に使用される農薬である有機リン剤の影響により、マラリアを媒介する蚊が、有機リン剤系殺虫剤に耐性を高い割合で持ちつつあることが明らかとなった。この殺虫剤耐性変異をホモ接合体として持つ個体も発見され注意が必要である。首都ワガドゥーグーではデング熱が問題となっており、その媒介蚊であるネッタイシマカはピレスロイド耐性を示すが有機リン剤に対しては感受性を維持している。これらの結果はブルキナファソにおける蚊媒介性感染症対策指針策定にあたり重要な基礎的知見となると考えられる。
