傳播瘧疾的蚊,每年接近造成五十萬人的死亡。462Please respect copyright.PENANAQ34bwTlWNr

暫時未有效疫苗抵擋瘧疾的關係,殺蟲劑暫時仍是對抗瘧疾的主流手段。462Please respect copyright.PENANAZ1bHPMu5SD

(圖2)研究(Ref1)發現其中一款傳播瘧疾的蚊,在攝氏27度或34度的時候,交配效率比19度的時候更之為高。462Please respect copyright.PENANAGldd5OFoYu

另外,長期日照亦會影響他們交配的效率。462Please respect copyright.PENANAiT7Bp7TDfi

(圖3)研究還發現,男性瘧蚊其中一條名為desat1的基因會導致牠們產生名Hepatacosane的化學物,吸引異性前來交配。462Please respect copyright.PENANA6nHwll1IwN

現時有傾向利用基因改造蚊子的手法來滅絕帶有疾病的蚊子,利用基因工程技術對desat1基因做手腳,有可能會增加機會達到預期的效果。462Please respect copyright.PENANAOQVx4YsX5g
