科學家們可能找到了造成「蜂群衰竭失調」(Colony Collapse Disorder,CCD)的元兇,這種新型蜜蜂疾病也許跟來自以色列的病毒有關,而病毒源頭可能跟從澳洲進口輸入美國的蜜蜂有關。
2004年第一次出現有關「蜂群衰竭失調」的報導,當時美國有23%商業蜂群受到影響,每個蜂群有50%~90%的蜜蜂無故消失。
昆蟲傳染病研究專家小組發現,在「蜂群衰竭失調」和「以色列急性癱瘓病毒」(Israeli Acute Paralysis Virus,IAPV)之間具有高度的關聯性,這種新型病毒3年前才被確認。
而在美國首次關於「以色列急性癱瘓病毒」的報告中,科學家們進一步補充說明指出,在很多美國蜂巢裡發現,該病毒是透過蜂蟎(varroa mite)這種寄生蟲來進行傳播。
Scientists are homing in on a possible cause of the new bee disease known as colony collapse disorder, linking it with a virus from Israel that may have arrived in the United States via shipments of live bees from Australia.
Since it was first reported in 2004, colony collapse disorder, CCD, has affected 23 percent of the commercial bee colonies in the United States, causing losses of from 50 to 90 percent of the bees in each colony.
A team of entomologists and infectious disease researchers are reporting a "strong correlation" between the colony collapse disorder and a virus, the Israeli Acute Paralysis Virus, IVAP, identified just three years ago.
This is the first report of IAPV in the United States, the scientists said, adding that this virus is transmitted by the varroa mite, found in many U.S. hives.
