Colony Collapse Disorder (CCD)
Researchers Ponder Crisis of Honeybee Decline

UNIVERSITY PARK, Pa. — Bees are in trouble. Serious trouble. But solving their plight may be as complicated as figuring out why they are dying off.
Penn State held the first International Conference on Pollinator Biology, Health, and Policy this week.
The conference ran from last Saturday to Wednesday and featured dozens of experts and speakers from around the world.
Experts from as far away as Brazil, Israel and Kenya gave their take on the decline of pollinating bees and other pollinators, and the impact it is having on crop production around the world.
Representatives from several government agencies, including the Environmental Protection Agency (EPA) and the USDA talked about the federal government’s response to pollinator decline, in particular Colony Collapse Disorder (CCD), which was first discovered by a commercial beekeeper in Pennsylvania in 2006.
At a press conference Monday afternoon, Jeff Pettis, leader of bee research at USDA’s Agricultural Research Service (ARS), said the impact of CCD has not waned since the term was coined four years ago.
It is a big reason why honeybees, in particular, are in decline. But he added it’s not the only reason.
“CCD is one of many things that affect honeybees. It is unsustainable,” Pettis said.
A survey two years ago, he said, showed a 29 percent decline in the number of managed commercial bee hives as a result of CCD and other factors.

INDIANAPOLIS, IND—Jeff Pettis continues to break the hearts of mystery lovers.
Two years ago he and other entomologists went to work on what sounded like the scenario for rip-roaring fiction: widespread, unexplained disappearances of honey bee workers that left the youngsters and queen behind for no obvious reason.
Questions and Answers: Colony Collapse Disorder

Case studies and questionnaires related to management practices and environmental factors have identified a few common factors shared by those beekeepers experiencing CCD, but no common environmental agents or chemicals stand out as causative. There are three major possibilities that are being looked into by researchers.
Pesticides may be having unexpected negative effects on honey bees.
A new parasite or pathogen may be attacking honey bees. One possible candidate being looked at is a pathogenic gut microbe called Nosema. Viruses are also suspected.
