埃及斑蚊,英文名為yellow fever mosquito,學名為Aedes aegypti,是白紋伊蚊的近親。631Please respect copyright.PENANAVK65aCbIRs

(圖1)男性品種不會叮人,只有女性品種才會叮人,藉著吸血等途徑傳播登革熱(Dengue Fever)等疾病。631Please respect copyright.PENANAovbeaRTBo7

殺蟲劑雖能殺滅蚊子,但蚊子亦逐漸展示出對殺蟲劑的抗藥性。631Please respect copyright.PENANA1ArW4Z56Xe
631Please respect copyright.PENANABQjx5M5H8g
而基於殺蟲劑會污染環境及危害部份雀鳥昆蟲健康關係,建立另類對付播毒蚊子的方法可謂有著絕對的迫切性。631Please respect copyright.PENANAKML42CdYBD

(圖2)有見及此,Oxitec公司(現為美國公司收購)培養出埃及斑蚊OX513A品種。631Please respect copyright.PENANAWbjIJymigd
牠們在幼蟲的時候需要四環黴素(Tetracycline)才能成功生長。在實驗室培植的時候,研究人員會在食物裡提供四環黴素,但當他們被放到野外的時候,便再也沒能取得足夠的四環黴素,沒能順利生長成為蚊子。631Please respect copyright.PENANAlnRBE6Au8Y
631Please respect copyright.PENANA2TKkwnL4BU
男性埃及斑蚊OX513A品種與女性正常品種交配的話,將有機會產生正常品種及OX513A品種的蚊卵。631Please respect copyright.PENANAtSrsy6WSGJ
631Please respect copyright.PENANAHaaFqrf21O
在野外缺乏四環黴素的情況下,正常品種有86–88%成功長大為蚊子,而OX513A品種則只有3-4%的成功率。631Please respect copyright.PENANAvHMxsdAyqP
631Please respect copyright.PENANALbcAaV6kH3
以這個方式推算下去的話,蚊子下一代的比率將會大幅度減低。631Please respect copyright.PENANAOnv6BK8TSG

(圖3)Oxitec公司在2010年英國開曼群島藉著此方式消除80%野外埃及斑蚊。631Please respect copyright.PENANA8edcovgFGu
而亦在2013年巴西巴伊亞州順利用上同樣方式消除~90%野外埃及斑蚊。631Please respect copyright.PENANAwbprLYY72g
631Please respect copyright.PENANAAJvzc1OxiA
今年2020年8月,他們同樣依這種方式在美國佛羅里達發放男性男性埃及斑蚊OX513A品種。631Please respect copyright.PENANA98FyChbP7G
631Please respect copyright.PENANAjbntCinTby
此舉泛起不少反對聲音,不乏違反動物權利及人權等等。631Please respect copyright.PENANA0bZvplaMF4
631Please respect copyright.PENANAAyLtP2mzxL
亦有人認為此舉會破壞生態平衡,奈何此方法只會滅殺埃及斑蚊,不會影響其他蚊子品種,其他物種可照樣進食其他蚊子品種代替,不見得有任何大影響。631Please respect copyright.PENANAkG526Ebuks
631Please respect copyright.PENANAIp2Qi8YfNr
至於亦有人認為埃及斑蚊有機會因而大遷徙到第二區域,這點反而有著潛在的可能性,值得探討一下。

睇番一大輪資料後,發覺原來依篇文所寫的方法係佢哋用係巴西的方法,18個月之內係有成效,之後蚊子數量回升。631Please respect copyright.PENANAMZAOqjZtJX
631Please respect copyright.PENANAEHn1TIoog6
今次美國所用的方法係OX5034,同舊原理差唔多,但女性BB會死,而男性BB唔會。631Please respect copyright.PENANArHodloSNiN
631Please respect copyright.PENANA6W2PE4fPJ6
無睇到佢哋媒體資料,只係睇咗佢哋之前所發出的學術文章,所以資料有錯,對不起。
