UC Davis bee scientists to address state beekeepers | Environment
DAVIS--Assistant professor Brian Johnson and Extension apiculturist Eric Mussen of the UC Davis Department of Entomology will speak at the 2012 California State Beekeepers Association's annual convention, set Nov. 12 through Nov. 15 in Cabazon. The meeting will take place in the Morongo Casino Resort and Spa.
Johnson will discuss “Completed and Ongoing Research at the Laidlaw Bee Research Facility” during the Nov. 15th session. He will be presenting information on two sets of experiments he and his associates conducted at the Harry H. Laidlaw Jr. Honey Bee Research Facility, headquartered on Bee Biology Road.
“First we collected data suggesting that high fructose corn syrup blends are not harmful to colonies and that they may even be preferable to sucrose solution in the context of commercial beekeeping,” Johnson said. “Second, we showed that rates of multiple and single viral infection are higher in commercial beekeepers than in queen breeders or small scale hobbyists. This suggests that management practices can strongly affect rates of pathogen infection and that future efforts should be directed to mitigating these effects.”
Mussen, who also serves as parliamentarian on the CSBA governing board, will speak on “Honey Bee Nutrition” on Tuesday, Nov. 13 and “Keeping Your Bees in the Hive” on Wednesday, Nov. 14.
“The nutrition talk basically is to provide the beekeepers with information on the complexity of nutrients that are found in both pollens and nectars of various blooming plants,” Mussen said. “The complexity of the macro- and micro-nutrients is what makes the pollens so valuable to a complete bee diet. The complexity also is the reason why we have not developed a man-made substitute that can adequately replace pollens in honey bee diets.”
“In the honey bee colony’s quest to obtain adequate nutrition, the foraging bees visit an acre equivalent of flower blooms that they seek out in the 50-square mile area over which the foragers can range,” Mussen said.
In his other talk, “Keeping Bees in the Hive”—a play on words in the title—Mussen will discuss what to do to “not allow honey bee colonies to swarm.” He also will tell why strong colonies require an abundant supply of good pollens and nectar all the active season. “And finally, I will mention ways in which bees can be confined to the hive for short periods of time to avoid pesticide exposure or for moving the hives to new locations.”
Time permitting, following the board of directors’ meeting, Mussen will deliver a third talk on “Africanized Honey Bees,’ tracing the history of the bees to 1956 when entomologist/professor Wawick Kerr imported 26 queen honey bees into Brazil from South Africa. Warwick hoped to hybridize tropical (African) and temperate climate (European bees) to obtain high honey production and better disposition. However, a beekeeper inadvertently released some of the descendants into the Western Hemisphere and they have now southern and central California.
