Amid dotted and sporadic outbreaks of the chikungunya virusin many pl廣告設計aces, transmitte道具製作d by the Aedes albopictus mosquito, a facility in Guangzhou’s Huangpu District nicknamed the “mosquito factory”, is working overtime. Guangzhou Wol活動佈置baki Biotech Co., Ltd.

Inside a temperatureandhumiditycontrolled laboratory, millions of mosquito eggs float in a nutrient solution. Robotic arms precisely sort pupae, and an automated pupae sex sorter filters out male策展 pupae with an e品牌活動rror mar道具製作gin of less than 0.5%. As the pupae mature into adults, the final error rate of male mosquitoesdrops below 0.3%.
According to the company, the mosquitoes it cultivates are Wolb參展achia-infected “sterile males”. When these males mate witVR虛擬實境h wild females that are uninfected, th玖陽視覺eir eggs fail to develop due to a phenomenon known as cytoplasmic 展場設計incompatibility, rendering them nonvi模型able and unable to hatch into larvae.

廣州“蚊子工廠”加急產百萬只“絕育雄蚊”:交配后使雌蚊的卵掉效
沈浸式體驗近期,由白紋伊蚊傳播的基孔肯雅病毒在多地點狀散發。都沒有。不模糊。在廣州市黃埔區,被譽為“蚊子工廠”的廣州威佰昆生物科技無限公司(以下簡稱“威佰互動裝置昆”)周產五百萬只“絕育雄蚊”,以生物技術阻斷蚊媒繁衍鏈。
裴母聞言,露出一抹異攤位設計樣的神色,目不轉睛的看著兒子,許久沒有說話。記者在恒溫恒濕的實驗室看到,數百萬蚊卵在營養液中沉浮,自動化機械臂精準分揀蛹蟲,自動蚊蛹牝牡分離機篩選出雄蛹,誤差率低于0.5%,最終成仙獲得的雄蚊誤差率低于0.3%。
據介紹,該企業培養出來的是攜帶沃爾巴克氏體的“絕育雄蚊”,與未攜帶該菌的野生雌蚊交配時,由于胞質不相容現象,所產的卵不克不及正常發育,無法孵化出幼蚊。
更奇妙的是,這種細菌可通過母系遺傳。威佰昆起首篩選出穩定攜帶該菌的雌蚊,樹立種群,年夜規模繁育后,再將數十萬計攜帶菌株的雄蚊按期釋放到目標區域。
由于雌蚊平生凡是只交配一次,一旦與“絕育雄蚊”結合,其產卵便宣佈無效。這就意味著,只需經過幾代持續釋放,目標區域的蚊子種群數量會年夜幅減少。據介紹,普通情況下,通過該項技術三周內人形立牌蚊子數量可減半,6-8周內野生蚊群密度能驟降80%以上。
