Gab es in der Regel bis 2005 nur 5 bis 10% an Völkerverlusten, so sind im Winter 2012/13 die Hälfte aller Bienenvölker in den USA dem mysteriösen Bienensterben zum Opfer gefallen, wie die New York Times letzten Freitag berichtet. Worauf dieses Massensterben auch Colony Colapse Disorder (CCD) zurückzuführen ist, weiß bisher niemand. Klar ist nur, dass es sich zumindest in den USA ausweitet.

BAKERSFIELD, Calif. — A mysterious malady that has been killing honeybees en masse for several years appears to have expanded drastically in the last year, commercial beekeepers say, wiping out 40 percent or even 50 percent of the hives needed to pollinate many of the nation’s fruits and vegetables. A conclusive explanation so far has escaped scientists studying the ailment, colony collapse disorder, since it first surfaced around 2005. But beekeepers and some researchers say there is growing evidence that a powerful new class of pesticides known as neonicotinoids, incorporated into the plants themselves, could be an important factor. The pesticide industry disputes that. But its representatives also say they are open to further studies to clarify what, if anything, is happening. “They looked so healthy last spring,” said Bill Dahle, 50, who owns Big Sky Honey in Fairview, Mont. “We were so proud of them. Then, about the first of September, they started to fall on their face, to die like crazy. We’ve been doing this 30 years, and we’ve never experienced this kind of loss before.
