The new UC California Cooperative Extension apiculturist, Elina Lastro Niño, has moved it to her website now that Eric Mussen has retired. Mussen, now Extension apiculturist emeritus, wrote the newsletter from 1976 to 2014 and loaded it on his UC Davis Department of Entomology and Nematology website. The editions are now archived.
The new home? It's on the elninobeelab website.
It's available online for free, of course. The newsletter is published bimonthly: in February, April, June, August, October and December. Niño relates: "If you wish to have this newsletter sent directly to your email address, please follow the instructions below. Enter this URL into your browser: https://lists.ucdavis.edu/sympa/subscribe/ucdavisbeenews. When it opens, it should relate to subscribing to this newsletter. Enter your email address and then click submit. It is time to decide whether to continue your hard copy subscription. The mailed subscription rate is now $25 per year (six issues). If you'd still like to continue this subscription please send a check by April 10, 2015 payable to the UC Regents and mailed to Elina L. Niño at the address in the signature block. Be sure to include your name and mailing address. If the check is not received you will not receive the next issue of the newsletter as a hard copy. This, of course, does not apply to those who have already prepaid for a certain time period."
In the newest edition, published today, you'll learn about how to treat those nasty Varroa mites, known far and wide (except in Australia, which doesn't have them) as beekeepers' Public Enemy No. 1.
Niño writes about HopGuard® II, "basically an 'old' product developed by BetaTec Hop Products, Inc., but it has an improved delivery system."
You'll also learn
- what Niño said when she addressed the the Avocado Pollination Seminar series
- that EPA is registering a new insecticide, flupyradifuron
- about exciting upcoming events, including a bee symposium, open house, and queen-rearing workshops, and
- some great information about how honey bees collect nectar.
How honey bees collect nectar is her Kids' Corner feature. "Usually after about three weeks of life as a house bee, all healthy honey bees in a normal, healthy colony become foragers," she writes. "They start every morning by going out into the world looking for the best sources of sugary nectar and protein-rich pollen. Some of them even collect water. Now, I'm sure you've seen these friendly ladies just buzzing along visiting flowers in your back yard. By the way, just a reminder, forager bees will not attack unless they feel threatened so just make sure you don't bother them and you should be fine (and tell your friends too!). "
Niño goes on to explain the process, and points out, as Mussen emphasizes, that honey is "not actually bee vomit as it never goes through a digestion (breakdown) process in the digestive tract of a honey bee." (Mussen officially retired in June 2014 after 38-years of service, but he continues to maintain an office in Briggs Hall and assists wherever he can, including writing a few articles for the newsletter.)
Niño, who joined the UC Davis Department of Entomology and Nematology on Sept. 1, 2014 from Pennsylvania State University—2600 miles away--is as busy as the proverbial worker bee.
“California is a good place to bee,” she told us recently. “I just wish I could have brought some of that Pennsylvania rain with me to help out California's drought."
Niño operates her field lab at Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, west of the central campus, and at her lab in Briggs Hall, on the central campus. Her aims: to conduct practical, problem-solving research projects; to support the state's beekeepers through research, extension and outreach; and to address beekeeper and industry concerns.
The mission of her program is "to provide support to California beekeepers and other relevant stakeholders through research, extension and outreach." Niño studies honey bee biology, health, reproduction, pollination biology, insect ecology, evolution, genomics and chemical ecology.

Extension apiculturist Eric Mussen of the Department of Entomology, University of California, Davis, writes an interesting bimonthly newsletter.
He's been writing from the UC Apiaries since he joined the department's faculty in 1976.
Never missed an edition. Not one. And his newsletters are eagerly awaited.
His newsletters and Bee Briefs are available online for free downloading. Or, folks can subscribe for free.
In the current edition of from the UC Apiaries, Mussen explores an article in Catch the Buzz about statistics released by the Apiary Inspectors of America (AIA) that show startling winter bee losses.
AIA and the USDA honey bee lab in Beltsville, MD, reported on losses from data collected for 22.4% of the country's 2.46 million colonies, Mussen said.
"We lost about 33.8% of those managed colonies," he wrote. "Similar to previous surveys results, 28% of the beekeepers stated that they found some totally empty hives reminiscent of colony collapse disorder (CCD).
"Beekeepers reported the following reasons for colony losses: starvation, 32%; weather, 29%; fall weakness, 14%; mites, 12%; poor queens, 10%; and CCD, 5% (Yes, that is 102% of the losses)."
"What caught my eye was the 32% starvation. Beekeepers usually do a pretty good job of paying attention to how much food is stored in the hives, and it is difficult to believe that they would allow a third of their colonies to die of starvation.
"Normally, it is pretty easy to determine when a colony has starved. The food, especially honey, is all gone and there are dead bees stuck head-first in the empty cells in the combs. Even to the uninitiated, it is obvious that the bees ran out of food and died."
But why did they die? You'll want to read his comments.
A honey bee newsletter, "From the UC Apiaries" newsletter, written by Cooperative Extension Apiculturist Eric Mussen of the UC Davis Department of Entomology Faculty, provides linformative and educational information for beekeepers and those interested in the plight of the honey bee.
In his latest edition, Mussen writes:
"Since years of study on colony collapse disorder (CCD) of honey bees have not produced the smoking gun (a single cause) for the malady, scientists are turning to potential multiple causes. The studies are designed to try to find synergistic interacttions of chemicals in the hive that may be damaging the bees. The dictionary definition of synergism is: interaction of discrete agencies or agents such that the total effect is greater than the sum of the individual effects. In other words, one plus one equals more than two. The question is: Can pesticide residues, infectious agents, and/or malnutrition combine to be much worse for the bees than simply the additive effect of each alone?"
