This past winter, about 30 percent of all the managed honeybees in the U.S. died. That's according to the U.S. Department of Agriculture. Such a die-off is no longer unusual. About a third of honeybees have ___1___ every winter since 2006.
Given that recent history, USDA entomologist Jeff Pettis characterized this as quote “___2___” given that quote "the problem does not appear to be getting worse."
Of course, the problem has been getting worse since at least the 1980s, when parasitic mites ___3___ the U.S. Our friend Apis mellifera has never recovered. Now so-called "Colony Collapse Disorder" or CCD continues to kill bees--who provide some $15-billion worth of economic good via pollination.
To really solve the problem would require much more than solving the mystery of CCD. It would require a ___4___ from the widespread use of pesticides that unintentionally impact bees and a ___4___ from the large-scale agriculture that forces them to ___5___ a single type of flower rather than their usual diverse diet. Plus, there's the globalization that allows bee-killing disorders to spread rapidly and easily. What a buzz kill.

據(jù)美國農業(yè)部透露,去年冬天,美國有30%的養(yǎng)殖蜜蜂死亡。對此,人們已見怪不怪了,因為自2006年以來,每年冬天蜜蜂數(shù)量就會銳減30%。
美國農業(yè)部昆蟲學家杰夫佩蒂斯稱之為“少許鼓勵”因為“這個問題并沒有惡化的趨勢”。
眾所周知,少說從20世紀80年代寄生螨首次入侵美國開始,這個問題就一直在惡化??蓱z的意大利蜜蜂從那以后就再也沒擺脫過厄運?!胺淙罕罎⒕C合癥”(CCD)至今仍是蜜蜂的殺手,勤勞的小蜜蜂傳粉采蜜的經濟貢獻約合150億的經濟商品呢。
要想真正挽救小蜜蜂,光解決蜂群崩潰綜合癥是遠遠不夠的。我們需要停止使用殺蟲劑,因為它們無形之中就會影響到蜜蜂的生存;還需要減少大規(guī)模農業(yè),因為這樣會使得蜜蜂傳粉采蜜對象過于單一。此外,在全球化的影響下,引發(fā)蜜蜂死亡的病癥極易傳播。哎~尸橫遍野咯~
