LEWISBURG, Pa. (AP) — Scientists investigating a mysterious ailment that killed many of the nation's honeybees are concentrating on pesticides and a new pathogen as possible culprits, and some beekeepers are already trying to keep their colonies away from pesticide-exposed fields.
After months of study, researchers are finding it difficult to tie the die-off to any single factor, said Maryann Frazier, a senior extension associate in Penn State University's entomology department.
“Two things right now ... that are really keeping us focused are the pathogen and the role of pesticides,” Frazier said...
Beekeeper Jim Aucker, of Millville, was left with just 240 of his 1,200 hives earlier this spring after the illness struck. He said he's back up to just under 600 now. He is convinced pesticides are playing a role.
“I have found spray materials in our dead hives. Whether it's 100 percent the cause, I'm not sure, but I'm positive it's not helping,” Aucker said. He doesn't plan to return to fields where he thinks there might be a pesticide problem.
