Honey Bee Losses Still a Problem in US (1/2)

Honey bees add billions of dollars in value to around one hundred thirty crops in the United States. But since the nineteen eighties, researchers have been concerned about the health of these valuable pollinators.

Worries grew after the winter of two thousand six. Some pollination services reported losses of anywhere from thirty to ninety percent of their hives. The beekeepers did not find dead adult bees as they often do after winter. Instead, the bees were gone. Experts gave a name to this mysterious situation: colony collapse disorder.

A report in Agricultural Research magazine, from the Department of Agriculture, takes a fresh look at C.C.D. It says the disorder is truly a serious problem. But it says there were enough honey bees to provide all the agricultural pollination needed last year.

Still, beekeepers reported losing about thirty-five percent of their hives in the fall and winter of two thousand seven. In two thousand six, it was thirty-one percent.

蜜蜂为美国约130种农作物增加了数十亿美元的价值。但是自1980年以来，研究人员就担心这些有价值的传粉媒介的健康问题。

2006年入冬以后担忧更加剧了。一些授粉服务商报告，到处都有蜂巢消失，消失的蜂巢占30-90%。养蜂人并没像往年一样，在冬天后，发现工蜂的尸体 。专家给这一神秘情况取名“蜜蜂衰竭失调”（C.C.D.）。

《农业研究杂志》一则由农业部获悉的报道重新探讨了C.C.D.问题。它说，失调的确是个严重的问题。但是，去年有足够的蜜蜂为美国完成所有需要进行的农业授粉工作。

仍然，养蜂人报告，2007年的秋天和冬天损失了约35%的蜂巢。2006年损失了31%。
