Anopheles funestus kháng thuốc diệt côn trùng pyrethroid tại Nam Phi
Tóm tắt
Tỉnh Bắc KwaZulu/Natal (KZN) của Nam Phi nằm giáp Mozambique ở phía nam, giữa Swaziland và Ấn Độ Dương. Để kiểm soát các vector gây bệnh sốt rét tại KZN, các ngôi nhà được phun hàng năm với DDT tồn dư 2 g/m2 cho đến năm 1996 khi việc xử lý chuyển sang deltamethrin 20–25 mg/m2. Tại Ndumu (27°02′ S, 32°19′ E), tỷ lệ bệnh sốt rét được ghi nhận đã tăng gấp sáu lần từ 1995 đến 1999. Các khảo sát Entomological cuối năm 1999 phát hiện nhóm muỗi
