Make way for the new beekeepers! Or "beeks," as they fondly call themselves in the apiary industry.
A short course on "Planning Ahead for Your First Hive" drew an enthusiastic group of prospective beekeepers last Saturday, Feb. 13 at the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, University of California, Davis.
Aimed at those with little or no beekeeping experience, the all-day course included lectures and hands-on experience. The instructors--Extension apiculturist Elina Niño, Bernardo Niño, Charley Nye and Patricia "Tricia" Bohls--explained what beekeeping is all about. The lectures covered honey bee biology, beekeeping equipment, how to start your own colony, and maladies of the hive. The participants also learned how to build a hive, how to install a package, how to inspect your hive, and how to monitor for varroa mites.
This was the first in a series of several beekeeping courses that began Feb. 13 and will conclude on March 20. All classes are filled, but folks can contact Bernardo Niño at elninobeelab@gmail.com or call 530-380-BUZZ (2899) to be put on a list.
Meanwhile, the instructors are busily gearing up for these courses, all filled:
Working Your Colonies on Feb. 20: For novice beekeepers who already have a colony and/or have taken a previous course, and seek to develop their skills. Lectures will cover maladies and biology review, products of the hive, and troubleshooting problems in the colony. Hands-on information will encompass colony evaluations, monitoring and managing pests, feeding your colony, and honey extraction.By the end of the course, participants will be knowledgeable about evaluating colonies, solving common beekeeping problems, extracting honey and wax, trapping pollen and propolis, and treating colonies for pests, the instructors said.
Queen-Rearing Techniques: (two separate sessions) March 12-13 and March 19-20: Topics will include honey bee queen biology, basics of selective honey bee breeding programs, various queen-rearing techniques, testing hygienic behavior, and assessing varroa mite levels. Participants will have the opportunity to learn about and practice multiple methods for queen rearing. “We will go through a step-by-step process for queen rearing via grafting, including setting up cell builders and mating nucs,” Elina Niño said.
The Niño lab launched a website last year at http://elninobeelab.ucdavis.edu/, and administers a Facebook page at https://www.facebook.com/elninolab/. In addition, Elina Niño writes a bi-monthly apiculture newsletter, free and online.

So true.
For her news story, reporter Jenny Starrs interviewed "Bee Detective" Jay Freeman of the Butte County Sheriff's Office (he's a detective all year long but a "bee detective" during almond pollination season and he also keeps bees).
"At the start of pollination season in 2010, the average hive cost $130 to rent," Starrs wrote. "Rental fees are $200 this year, and will continue going up as hives continue to die off. The industry is becoming increasingly volatile, increasingly expensive and thus, increasingly criminalized."
In past years, we remember hearing about several hives stolen here, several hives stolen there, and a few more over there. But now bee hive thievery is rampant. Detective Freeman reported hundreds of hives stolen and cited the numbers: 240 from an operation in Colusa County, 64 from an operation in Butte, 280 in Sutter County...the list seems endless.
The California State Beekeepers' Association has now set up Bee Theft Alerts on its web page.
It's good to see that the CSBA is offering a reward up to $10,000 for the arrest and conviction of persons stealing CSBA members' bees or equipment. CSBA is also encouraging beekeepers to report the thefts, no matter how small.
It's working. The Butte County Sheriff's Office arrested a suspect Feb. 6 and charged him with stealing 64 bee hives from Olivarez Honey Bees Inc. in Chico and trucking them to a Stanislaus County almond orchard.
Extension apiculturist emeritus Eric Mussen of the UC Davis Department of Entomology and Nematology--his career spanned 38 years--told us last week that apparently beekeepers or people with beekeeping knowledge are stealing the hives. "Maybe they used to work for some of these beekeeping operations, and know where the hives are," he said. So, in the dead of the night, the thieves are moving in the big trucks and forklifts, hauling them away, and then renting them to unsuspecting almond growers. The culprits pocket the money and never return for "their" colonies.
“Most people, when they lose their hives, figure they're never going to get found,” California State Beekeepers' Association media director Joy Pendell told Starrs. “It's very frustrating for us, because we go all winter without any income. So we put all this money and work into them for months, and we're about to have our payday and someone just goes and steals it.”
The Bee Culture journal, edited by Kim Flottom, has also sounded the alert.
"If you have had any hives stolen within the last couple years, please email Joy Pendell directly at jpendell11@gmail.com with brand numbers, a description and pictures," Flottum wrote. "The California State Beekeepers would like to create a complete history of hive theft in our industry to share with law enforcement and interested media outlets. If you know of a theft victim who is not a CSBA member, please pass along this information so they can report as well. The CSBA represents the interests of all California beekeepers plus they would like to create a summary of bee theft both inside and outside of our organization."
At a recent meeting of the California Bee Breeders' Association that we attended in Ordbend, Glenn County, members talked about stepping up patrols and recruiting volunteers to monitor remote areas at night and early morning.
Just call it "The Sting" operation.
Unfortunately, all this bee thievery may worsen. Gordy Wardell recently reported in the Project Apis m newsletter that California's total number of almond acreage is now at 1 million.

The species has spread to at least seven counties in California since June 2013, says UC Davis medical entomologist Anthony Cornel of the UC Kearney Agricultural Research and Extension Center, Parlier, and the UC Davis Department of Entomology.
“It's an issue of great concern, especially as current control methods do not appear to be working well," says Cornel, who collaborates on research projects in Clovis, Fresno County, with the Consolidated Mosquito Abatement District. The district, based in Fresno, covers 1,058 square miles, including part of Kings County.
“We can't predict how far this mosquito will go in California,” he says, but it has spread “south of Fresno to San Diego. The furtherest site north is Madera in the Central Valley, but it's also been found in the more coastal area of Menlo Park in San Mateo.”
As far north as Sacramento?
“I don't want to exclude the possibility that it may spread as far north as Sacramento,” said Cornel, who collects, rears and researches mosquitoes from all over the world, including the United States, Mali, Cameroon, Comoros, Tanzania, South Africa and Brazil. “We need to see if it overwinters as eggs or adults or both.”
Infected Aedes aegypti can transmit dengue, yellow fever, Zika and chikungunya viruses. The Zika virus was first identified in Uganda in 1947 in rhesus monkeys, according to the World Health Organization. It was subsequently identified in humans in 1952 in Uganda and the United Republic of Tanzania. Outbreaks of Zika virus disease have been recorded in Africa, the Americas, Asia and the Pacific.
Although the mosquito species is in California, it's important to point out that there are no reported cases of locally transmitted Zika virus in the state or in contiguous United States, according to the Centers for Disease Control and Prevention. The cases have all involved travelers returning home from countries plagued with disease outbreaks.
Cornel and his colleagues published a 27-slide document, “Surveillance and Control of Aedes aegypti Mosquito in Clovis, Calif.,” on Feb. 8 in F1000 Research, http://f1000research.com/slides/5-149. They called attention to the widespread invasion and establishment of the species in California. The research, illustrated with maps, is the work of Cornel and Yoosook Lee of UC Davis; Stephen Dobson of the University of Kentucky; Corey Bansfield of MosqMate Inc. and Jodi Holeman, Mark Amireno, Charles Smith and Stephen Mulligan III of the Consolidated Mosquito Control District.
The California team collaborates with University of Kentucky scientists to develop novel control strategies. One trial involves coating male mosquitoes with insect growth regulators, which are passed on to the females. Males are also infested with a biopesticide or “a good bacteria-like organism,” Wolbachia. “The male transfers it to the female, which affects the ovaries and negatively affects immature development,” Cornel explains. “It's not new, but it's not been employed in large trials.”
The researchers target mosquito breeding sites, primarily yard drains. “Despite the drought and the elimination of visible bodies of water, such as bird baths, pet bowls and flower pots, there's a major issue: yard drains,” Cornel says. “Yard drains installed in new home developments empty into the gutter or street and are cryptic breeding sites for mosquitoes.” He speculates that these mosquitoes are breeding underground.
“These drains are not easily accessible and we can't see the mosquitoes,” Cornel points out. “We need to blow out the water and plug these yard drains to eliminate these breeding sites.” He suggests that cities everywhere address this public safety issue and “redesign the yard drains.”
It's crucial for the public to become involved, Cornel emphasizes. “We have to focus on public education. We have to get the message across to eliminate mosquito breeding sites. We can't go to every house. We must rely on the public to eliminate the breeding sites.”
It's possible—but he hopes not—that what is now a “mosquito nuisance” will result in a disease outbreak.

Shades of Shirley Temple, maybe?
A curly haired tarantula at the Bohart Museum of Entomology at UC Davis could have been named for...drum roll..Shirley Temple.
The curly haired tarantula, or Brachypelma albopilosum, proved a big hit at the Bohart Museum on Saturday, Feb. 13 during the campuswide UC Davis Biodiversity Museum Day. Graduate student Ziad Khouri, who is studying for his doctorate with Lynn Kimsey, director of the Bohart Museum and professor of entomology at UC Davis, intrigued visitors with the spider.
It's native to Costa Rica and Honduras. And like other members of Brachypelma, it's a CITES listed species. That means it's on the Convention on International Trade in Endangered Species (CITES), and under international restrictions for quotas and trade permits.
Khouri noted that in the past, it was overharvested for the pet trade, although the current availability of captive bred specimens has decreased pressure on wild populations. Nevertheless, habitat loss and destruction continue to threaten he curly hair tarantula and many other species.
Tarantulas were in the news this week when scientists revealed that they named a newly discovered tarantula found on the Folsom Prison grounds after singer/songwriter Johnny Cash, the legendary "Man in Black." Its scientific name? "Aphonopelma johnnycashi."
The announcement was part of a newly released study by biologists Chris Hamilton and Jason Bond of Auburn University and Brent Hendrixson of Millsaps College involving nearly 3,000 tarantulas from across the American Southwest. Fellow scientists describe their 340-page study as "unequivocally the most important work on tarantulas ever done."
That brings to mind the Johnny Cash song, "Folsom Prison Blues" in which he lamented "I ain't seen the sunshine since I don't know when."
Wonder if "The Man in Black" ever saw "The Critter in Black," now his namesake Aphonopelma johnnycashi.

Feb. 14 was a perfect day for foragers, as the temperature climbed into the '70s, an unusually warm February day.
The site: The Glen Cove Marina in Vallejo, Calif., across the Carquinez Straits from Crockett.
We focused on one Bombus vosnesenskii--but only because the other four buzzed out of camera range. For 10 minutes, we watched her work the rosemary, buzzing from flower to flower as honey bees and syrphid flies zeroed in for their share, too.
But look at the bumble bee's pollen load, reminiscent of Halloween candy corn, those triangle-shaped yellow, orange and white-layered sweets.
"She obviously switched from one plant species with pale pollen to one with orangish pollen and maybe back again during her foraging bout," noted native polinator specialist Robbin Thorp, distinguished emeritus professor of entomology at UC Davis and co-author of California Bees and Blooms: A Guide for Gardeners and Naturalists (Heydey) and Bumble Bees of North America: An Identification Guide (Princeton University Press.)
"A fickle forager," Thorp declared. "Rosemary has whitish pollen, but it is usually a nectar resource for honey bees and others. So there must be some other plants being visited by B. vos. females in the area."
Indeed there were. California golden poppy (the state flower), wild radish, oxalis, and mustard.
"Detective" Thorp quickly figured it out. "The wild radish, mustard, and oxalis all have yellow pollen. Poppy has orange pollen. So it looks like your female may have started on rosemary (upper whitish part of the load), moved over to poppy for a while, and back to rosemary (bottom pale part of the load). Since poppy produces no nectar, visits to rosemary are primarily to tank up on nectar for flight fuel and apparently to collect some pollen there as well. It is often said that a mix of different pollen types is best for bees, so she is picking up a balanced diet for her babies."
Bottom line: When you capture an image of a bumble bee, you may not know where it's going, but a top-notch pollinator specialist can tell you where it's been!
