Tóm tắt

Bài bình luận và thảo luận về một bài báo gần đây khuyến khích việc sử dụng Nothobranchius guentheri, một loài cá lia thia nhỏ ở châu Phi từ Đảo Zanzibar như một công cụ để kiểm soát ấu trùng muỗi trong các thủy vực tạm thời trên khắp châu Phi được trình bày. Các lập luận về các điểm chính; (1) khả năng thành công thấp trong việc giới thiệu cá lia thia hàng năm, (2) hiệu quả kiểm soát muỗi thấp trong thực địa, (3) những mối đe dọa sinh thái, và (4) các vấn đề đạo đức được kể chi tiết. Mặc dù có những vấn đề nghiêm trọng liên quan đến các bệnh do muỗi truyền ở châu Phi nhiệt đới và các nơi khác, chúng tôi khuyến khích các phương pháp kiểm soát sinh học chịu trách nhiệm đối với các vectơ ký sinh. Chúng tôi chỉ ra rằng hiệu quả của việc chuyển giao Nothobranchius là thấp (các nỗ lực trước đó đã thất bại), khả năng kiểm soát ấu trùng muỗi hiệu quả trong điều kiện thực địa là không đáng kể và những mối đe dọa sinh thái từ việc chuyển giao Nothobranchius từ trong và ngoài phạm vi phân bố tự nhiên là nghiêm trọng. Chúng tôi phản đối bước tiếp theo được đề xuất của dự án, tức là thử nghiệm thực địa ở Tanzania.
