Backyard Orchard News
“You’re not going to be able to jump on the pomegranate bandwagon with your pockets bulging with gold without a lot of hard work,” Kevin Day, farm advisor with UC Cooperative Extension Tulare County, told a reporter for a news story published May 14 in the Western Farm Press.
Yes, hard work.
Day told Western Farm Press that from 2006 to 2009, the number of acres in California planted with pomegranate trees "has increased from 12,000 or 15,000 acres in 2006, to 29,000 acres in 2009."
“We’ve doubled in three years, and that’s a lot of young pomegranate trees,” he said.
And that's a lot of work for the honey bees, too.
Our "orchard" of one pomegranate tree is buzzing with bees.
Just when we thought they'd forgotten their old buddy--"old" because the pomegranate tree was planted in 1927--here they come in the late afternoon. One by one, two by two, they head for the blossoms to gather the nectar and roll in the pollen of the papery blossoms.
Gold may bulge from the pockets of pomegranate orchardists, but a different kind of gold bulges from the honey bees--pollen.

The competition was fierce.
We're talking 800 postdoctoral scholars on the UC Davis campus, 12 finalists and two winners.
Chemical ecologist Zain Syed, who helped discover the mode of action for the insect repellent DEET in the Walter Leal lab, UC Davis Department of Entomology, emerged as one of the two winners.
The occasion: the sixth annual postdoctoral scholar research awards, sponsored by the UC Davis Postdoctoral Scholars’ Association and the Office of Graduate Studies.
Syed and fellow recipient Izumi Maezawa of the Department of Pathology and Laboratory Medicine, UC Davis Health System, each received a certificate and a $500 cash prize.
So, the next time you’re applying DEET to ward off mosquitoes, you can thank Leal and Syed for why mosquitoes won’t go near you. For the past 50 years, scientists assumed that DEET jams the senses of a mosquito or masks the smell of the host.
Not so. Mosquitoes can smell DEET and they avoid it because it smells bad to them. No jamming. No masking. Just a smell that's not in their comfort zone.
The chemical ecologists identified the olfactory receptor neuron in the antenna that detects the repellent. Their work led to one of the most popular research articles ever published in the Proceedings of the National Academy of Sciences (PNAS). The research paper has been loaded 9317 times from August 2008 through April 2009.
What this research means is we may see a whole new direction in the development of novel and promising insect repellents.

“Zain has an an encyclopedic knowledge of the literature and he designs well-thought experiments,” said Leal, also praising him as “a good mentor to students in the department, college and elsewhere on campus.”
“Zain is the type of postdoc that every principal investigator dreams about one day having in their own laboratory,” wrote professor Gabrielle Nevitt of Neurobiology, Physiology, and Behavior,
Entomology professor Penelope Gullan, who supported the nomination, said: "As a faculty member in the same department as Dr. Syed, I have watched his research progress and accomplishments over the past four years. His recent achievements have been truly outstanding in terms of significant research findings and publications in highly rated journals."

Honey bee geneticist Robert E. Page Jr. is in good company.
Good company, indeed.
Think scientists Marie Curie, Albert Einstein and Charles Darwin.
Page, who received his doctorate in entomology from UC Davis in 1980 and then became a noted geneticist at the Harry H. Laidlaw Jr. Honey Bee Research Facility, UC Davis, has just been elected to the oldest scientific academy of science, the Germany Academy of Sciences Leopoldina, which dates back to 1652.
Besides Darwin, Curie and Einstein, the academy membership has included explorer Alexander von Humboldt and author Johann Wolfgang von Goethe.
Overall, some of the most brilliant and innovative minds in physics, chemistry, biology, philosophy and mathematics.
“Alexander von Humboldt and Charles Darwin are my heroes,” said Page. “I am truly honored to belong to an academy that lists them as former members.”
Page is known for his pioneering research in the behavioral genetics of honey. His expertise includes Africanized bees, genetics and evolution of social organization, sex determination and division of labor in insect societies. His work has graced the covers of such respected journals as Naturwissenschaften, Nature, Genome Research, Cell and BioEssays.
Page, former chair of the UC Davis Department of Entomology, "officially" retired from UC Davis in 2004, but he didn't stay retired. Arizona State University recruited him that same year to organize three departments (biology, microbiology and botany) into ASU’s
“Rob Page is one of the most gifted scientists, administrators, and teachers I have had the privilege to know in 30 years in academia,” said James Carey, UC Davis professor of entomology and program director of the Biodemographic Determinants of Life Span project, who collaborates with Page. “Those of us who have worked with him congratulate him and are proud to call him our colleague and friend.”
UC Davis chemical ecologist Walter Leal, professor and former chair of the Department of Entomology, described Page as “one-of-a-kind: a premier scholar and an exemplary administrator.”
Rob Page's specialized stock of honey bees is legendary, too. It's back at UC Davis.
We first saw these special honey bees when bee breeder-geneticist Michael "Kim" Fondrk, who manages the Page stock, trucked the bees to Dixon to pollinate an almond orchard. The San Francisco Chronicle covered the story. Fondrk opened a hive to point out the queen bee, the worker bees and the drones.
And just as beautiful is the well-deserved honor that honey bee geneticist Robert E. Page Jr. just received./st1:place>/st1:placename>/st1:place>/st1:placename>/st1:placetype>/o:p>/o:p>/o:smarttagtype>/o:smarttagtype>/o:smarttagtype>/o:smarttagtype>
Frame of Bees
UC Davis forensic entomologist Robert Kimsey loves flies.
So, every chance I get, I shoot an image for him.
Many of the images wind up in his classroom PowerPoint presentations.
"Keep 'em coming," he says.
So, I shoot flies. Yes, indeed. I shoot flies. No, I am not a candidate for a 12-step program. Well, not yet.
Truth is, we think of flies as noxious. We don't think of flies as having parts like a head, abdomen and thorax--or compound eyes, arista, antenna, prescutum, scutum, scutellum, balancer and mesothorax.
They do, though.
Alive or dead.
And some are even pretty--especially when they're touching down on delicate pink blossoms.
Pretty in Pink?
Colony collapse disorder (CCD), the mysterious phenomonen characterized by honey bees abandoning their hives, is still with is, and the cause is still mysterious.
Over the past three years beekeepers throughout the United States have reported losing from one-third to 100 percent of their colonies to CCD, says UC Cooperative Extension Apiculturist Eric Mussen, a member of the UC Davis Department of Entomology Faculty since 1976 and a noted authority on honey bees.
The bees just vanish, leaving behind the queen, the immature brood (eggs, larvae and pupae) and stored food.
The calamity of CCD.
The queen, in peak season, lays about 2000 eggs a day. The worker bees serve as the nurse maids, nannies, royal attendants, heating and air conditioning specialists, foragers, guards and undertakers. They feed their mother (the queen) and their brothers, the drones. The sisters are their brothers' keepers. The drones' only function is to mate with the queen.
The worker bees pollinate about 100 crops in California, including nuts, fruits and vegetables. They just finished pollinating California's 700,000 acres of almonds. Now they're pollinating pomegranates, tangerines, lemons, squash, cucumbers and other fruits and vegetables in orchards and gardens near you.
Bring on National Pollinator Week, June 22-28.
Meanwhile, it's good to see that Häagen-Dazs Häagen-Dazs is continuing to support honey bee research at UC Davis and Pennsylvania State University. Back in February 2008, the premier ice cream brand launched an educational campaign to save the bees and just unveiled a newly updated site. One of the next projects: the Häagen-Dazs Honey Bee Haven, a half-acre bee friendly garden at the Harry H. Laidlaw Jr. Honey Bee Research Facility, UC Davis. Designed by a Sausalito team, the haven will be implemented this summer and publicly dedicated in October.
The haven will be a year-around food source for bees and other insects, such as butterflies, bumble bees and syrphids. Other goals: to create a public awareness of the plight of the honey bee, and to educate visitors about bees and the kinds of bee friendly plants they can choose for their own gardens.
Bottom line: let's keep our bees healthy. Mussen suspects that CCD is caused by a combination of factors: malnutrition, pesticides, parasites, diseases and stress.
If CCD has a face, then two photos can tell the story. First, look at the photo of healthy bees and then look at the photo from an abandoned hive. The bee antenna poking through an abandoned cell is just plain sad.
The queen bee, the sisters, the brothers, the brood--all gone.
The calamity of CCD.
