It's not spring, but don't tell that to the folks at the Harry H. Laidlaw Jr. Honey Bee Research Facility at the University of California, Davis.
Today bee breeder-geneticist Michael "Kim" Fondrk mowed the lush green grass around the apiary. Bee breeder-geneticist Susan Cobey, manager of the Laidlaw facility, continued preparing for a series of specialized bee courses. She tended the hives with beekeeper and junior specialist Elizabeth Frost and beekeeper Tylan Selby, a first-year entomology student.
The conference room buzzed with ideas for an upcoming tour. Following the meeting, Extension Apiculturist Eric Mussen of the UC Davis Department of Entomology faculty talked "bees 'n almonds" with Tabatha Yang, education and outreach coordinator for the Bohart Museum of Entomology on the UC Davis campus. Yang will be conducting the first of what will probably be many tours at the Laidlaw facility.
The tours will include the half-acre Häagen-Dazs Honey Bee Haven and the quarter-acre Campus Buzzway. Both are bee friendly gardens that will provide a year-around food source for the bees, and educational opportunities for visitors.
Meanwhile, oblivious to the people activity, the bees continued to gather pollen and nectar from nearby almond trees.
"The queen bees are really busy laying eggs," Cobey said. That means more workers, more drones and more queen bees.
During the peak season, a queen bee can lay 2000 eggs a day, Cobey said.
That's definitely springing into action.
Examining Almond Blossoms
Lovely almond blossoms
A sure sign of spring: trucks loaded with bee hives heading out to the almond orchards.
Yes, almond pollination season is almost here.
California has approximately 700,000 acres of almonds, and each acre requires two hives for pollination.
Since California doesn't have that many bee colonies, beekeepers from all over the country, some from as far away as Florida, are trucking in their bees.
A scene today in the Meadowview neighborhood, Sacramento: a truck loaded with hives and towing a forklift. The forklift? Quite necessary for easy movement and placement of the hives in the soggy orchards.
The almond pollination season begins around Feb. 10 and continues until approximately March 10. This encompasses the early, mid- and late varieties of almonds.
When asked today about the status of colony collapse disorder (CCD), Extension apiculturist Eric Mussen of the UC Davis Department of Entomology, told us: "The colonies being delivered to the orchards currently should be in pretty good shape but CCD still is depleting those numbers in many commercial beekeeping operations in California and across the country."Let's keep our fingers crossed.
It’s raining in northern California like the proverbial cats and dogs--and all the more reason to think of vacations.
Extension apiculturist Eric Mussen, member of the UC Davis Department of Entomology faculty, received a query last week from a family planning a camping trip to a public park in the Midwest.
A daughter is allergic to bee stings, so the family wanted to know two things:
1. Is there any way to find out what a bee population is in a specific area?
2. How can we avoid bee stings?
His answers are informative:
Is there any way to find out what a bee population is in a specific area?
Usually, the only records that are kept deal with the number of colonies registered by the beekeepers in a state once a year. If the beekeepers are commercial beekeepers, they are likely to move the colonies around for purposes of crop pollination or producing honey crops. Unless you knew all the beekeepers and their patterns of operation, there is no way to know where the colonies are.
If this is a good honey producing area, beekeepers might be moving their bees into it. You could call the park (if it is one) and see if they allow beekeeping on the park grounds.
Even if they don't, if there is good bee forage in the area (nectar and pollen), some honey bees are apt to be living around the area in "feral" colonies--not managed by anyone.
How can we avoid bee stings? Best preventative measures?
Honey bees do not tend to sting anything very far from the nesting location, unless you happen to step on one, etc. They are busy collecting water, nectar, pollens, or propolis (plant resins they use to glue things in the hive.) If something comes near the nesting location, and the bees respond to the approaching threat, then there might be some stinging.
What are the best preventative measures? This pertains to wasps, too, which sting more people in the woods than honey bees ever do. Keep your eyes open for "directed" flight by insects in an out of a specific spot. That is likely to be the nest entrance. Keep away from there.
If bees or wasps come flying out toward you, don't swing at them or try to blow them away from your face. You'll get stung immediately. If you are not yet stung, just stand very still for a moment, then ease yourself out of the area with no flailing or swinging of the arms, etc.
Put a lot of distance between you and the nest without running.
If they are all over you and stinging, then run first and work on the stings later. Honey bee stings stick in your flesh and give off "alarm pheromone," which leads to more stings in the same place. You do not want to continue to be a target.
If stung, look for the sting when you get a chance. If it is honey bees, the sting will be there. Scrape it off with a finger nail, before all the venom is pumped into the skin.
Honey bees are attracted more to yellow and blue than to other colors. Honey bees treat red and black as black. Black is bad if bees are stinging in the area. Pastel and white colors usually are best around bees.
Honey bees are attracted to odors reminiscent of lemon and are shocked by the smell of bananas--just like their alarm odor. (The aroma of bananas is similar to the scent of a bee's alarm pheromone.)
Final thought, even if there are bee hives or nests around, hardly anyone ever gets stung by them. They do their thing and you do yours, and there should not be any conflict under normal circumstances.***

Flight of the Honey Bee
Dragonflies, damselflies, dermestids and native bees.
Does an entomological life get any better than this?
Those are some of the topics to be discussed at the next meeting of the Northern California Entomological Society, set for Thursday, Feb. 4 in the California Department of Food and Agriculture (CDFA) Plant Diagnostic Lab building, 3288 Meadowview Road, Sacramento.
The meeting, to be held from 9:15 to approximately 3 p.m., is open to all interested persons. Membership dues are $10 a year, according to secretary-treasurer Eric Mussen, Extension apiculturist and a member of the UC Davis Department of Entomology faculty (email@example.com).
Patrick Foley, a theoretical population biologist and pollination biologist at California State University, Sacramento, will present a talk on "Native Bees of the American and Consumnes River."The schedule:
9:15 a.m.: Registration and coffee
9:45: “Native Bees of the American and Cosumnes Rivers” – Patrick Foley, Sacramento State University.
10:30: “Spotted Winged Drosophila, Drosophila suzukii: Research, Integrated Pest Management and Control” – Janet Caprile, Contra Costa County UC Cooperative Extension.
11:15: “Section 18 Pesticide Registration” – Margaret Reiff, Pesticide Registration, Department of Pesticide Regulation.
12:00 : Lunch (orders will be taken at the meeting) – $15
1:15 p.m.: “Neo-Tropical Odonata” (Odonata is an order of insects encompassing dragonflies (Anisoptera) and damselflies (Zygoptera). – Rosser Garrison, CDFA

The Northern California Entomology Society meets three times a year: the first Thursday in February; the first Thursday in May, at UC Davis; and the first Thursday in November in the Contra Costa Mosquito and Vector Control District conference room, Concord. Agricultural biologist Matthew Slattengren of the Contra Costa County Department of Agriculture serves as president.
The society is comprised of university faculty, researchers, pest abatement professionals, students and other interested persons.
Almond pollination season is approaching, and with it, come concerns.
Mussen, a former New Englander who has seen dozens of almond pollination seasons in California (he's been a member of the UC Davis Department of Entomology since 1976), says California now has approximately 710,000 acres of almonds. Each acre requires two hives for pollination.
Since California doesn't have that many bees, beekeepers from around the country truck in their colonies. The going rate per hive over the last several years has ranged from $100 to $150.
Generally, California's almond pollination season starts around Feb. 10, Mussen says, and ends around March 10. That takes into account the early, mid- or late varieties that bloom at different times. However, the pollination period for each individual orchard is around 10 days.
The flight hours of a honey bee during almond pollination season? Approximately nine hours a day over a 10-day bloom period.
And what are flight hours? Mussen defines "flight hours" as "the number of hours above 55 degrees when the wind is less than 15 miles per hour, given a sufficient level of sunlight without rainfall."
"I believe that if the tree varieties overlap well in bloom, the bees usually have moved the pollen around in the morning and early afternoon on good flight days," he writes in his newsletter. "That probably requires only about four hours a day."
Of course, poor weather can interfere significantly with "fertilization and nut set," Mussen says, "but it would not be the fault of the bees."
As a service to beekeepers and growers, a retired beekeeper posts information on the Almond Board of California Web site indicating who's renting colonies and who needs pollination.
