What's happening with the honey bees?

Those following the mysterious phenomonen known as colony collapse disorder (CCD)--characterized by bees abandoning their hives--are eagerly waiting the latest developments.

So, when UC Davis bee breeder-genetist Susan Cobey recently offered a class on queen-bee rearing at the Harry H. Laidlaw Jr. Honey Bee Research Facility, UC Davis, she invited Cooperative Extension Apiculturist Eric Mussen to address the group. 

Mussen, who is entering his 33rd year as a member of the UC Davis Department of Entomology, is considered one of the top authorities on honey bees in the country, and indeed the world. News media--including the Associated Press, New York Times, Boston Globe, BBC, Los Angeles Times and Good Morning, America--seek his expertise.

Lately he's been asked if the newly published research work in Spain "solves" the global mystery of CCD. It does not.

"It is true that we have available to us an antibiotic that, when used properly, practically eliminates the disease-causing fungus, Nosema ceranae, from our colony populations," he wrote today in answer to an inquiry.  "However,  in many cases, nosema-free colonies continued to dwindle to nothing very quickly in many parts of the country. Whatever the causes of that collapse may be, elimination of nosemosis, alone, is not adequate to improve the health of our colonies enough that they survive."

"We need to increaes our research efforts on this malady," Mussen said, "so that we can assure the existence of healthy honey bee colonies for the production of the fruits, vegetable and nuts that make up the healthiest one third of our daily diets." 

Freerk Molleman, a postdoctoral scholar in professor James Carey's lab at UC Davis, kindly video-taped Mussen's hour-long lecture to Cobey's class.

Here it is: what's happening with the bees.
