Honey bee guru Eric Mussen, Extension apiculturist and a member of the UC Davis Department of Entomology faculty, is quoted in a Dec. 6 article in the Epoch Times about colony collapse disorder (CCD).
CCD is the mysterious phenomenon characterized by adult bees abandoning the hive, leaving behind the queen bee, brood, and food stores.
The gist of the Epoch Times article: The European Commission recently published its concerns about honey bee health.
In a communiqué, the commission sought to clarify the key issues related to bee health and key actions that it intends to take to address them.
"Beekeeping is a widely-developed activity in the European Union (EU), both at professional (keepers with over 150 hives) and hobby level," the communiqué began. "There are around 700,000 beekeepers in the EU out of which around 97% are non-professional accounting for around 67% of EU hives. Honey production is estimated to be close to 200,000 tons. Beekeeping is also associated with the production of other products such as wax, royal jelly, propolis, etc."
Epoch Times reporter Marco 't Hoen subsequently sought out Mussen for information on CCD and honey bee health in the United States. Mussen told him that CCD is a worldwide problem.
Twenty-five percent of beekeepers in the United States have recurring problems with CCD, Mussen said. The colonies range in size from one to 15,000.
Wrote the reporter: "He (Mussen) believes that in the U.S., CCD is caused by an infectious disease, which they have not yet identified. His reasoning is based on the fact that when bees are introduced to replace the dead one, they die as well. But when the hive is cleaned properly the new bees can survive."
Indeed, CCD is linked to multiple causes, including diseases, pests, pesticides, malnutrition and stress. Weakened colonies don't fare well.
The Epoch Times article quoted USDA statistics indicating that bee pollination of crops "is worth $15 billion per year" in the United States. For example, "the almond industry in California alone used about half of the 2.3 million colonies in the country in 2009 for pollination." In the European Union, about 700,000 beekeepers maintain almost 14 million colonies, according to the EC communiqué.
As an aside, U.S. beekeepers are now gearing up for the California almond season, which usually starts around Feb. 1. The state has more than 700,000 acres of almonds and each acre requires two hives for pollination. Since California doesn't have that many bees, bees are trucked here from all over the country.
It's a gold rush of sorts in the Golden State.
California, here we come!
There's an "alarming resurgence in the population of bedbugs" in the United States, according to the Centers for Disease Control and Prevention (CDC).
The exact cause is not known, but the CDC says it could be linked to "increased resistance of bed bugs to available pesticides, greater international and domestic travel, lack of knowledge regarding control of bed bugs due to their prolonged absence, and the continuing decline or elimination of effective vector/pest control programs at state and local public health agencies."
The Los Angeles Times warned in a Dec. 4 headline: L. A.'s Slow Trickle of Bedbugs May Turn Into a Flood.
That's a big "bah-humbug" for the holidays.
Senior museum scientist Steve Heydon of the Bohart Museum of Entomology, UC Davis, was quoted as saying:
Remember the exciting news article published in November of 2009 in Science Daily about how an orchid species on the Chinese island of Hainan "fools its hornet pollinator by issuing a chemical that honey bees use to send an alarm?"
The research was first published in Current Biology, a Cell Press publication.
"The discovery explains why the hornets, which capture honey bees to serve as food for their larvae, have been observed to literally pounce on the rewardless Dendrobium sinense flowers," the Science Daily author wrote.
Can you imagine? Hornets "detect" one of their favorite foods--honey bees--and they pounce on the flower and come up empty-handed or "empty-mouthed?"
The orchids produce a deceptive chemical, a compound called Z-11-eicosen-1-ol, described as "a rarity even in the insect world."
One of the researchers involved in this study--and hundreds of other insect communication studies--is world-renowned chemical ecologist Wittko Francke (top photo) of the University of Hamburg, Germany.
And now he's coming to the University of California, Davis, to present a seminar.
Francke will speak on "Insect Semiochemicals: Structural Principles and Evolution" at a UC Davis Department of Entomology seminar on Wednesday, Dec. 8 from 12:10 to 1 p.m. in 122 Briggs Hall, off Kleiber Hall Drive. He'll be introduced by host and fellow chemical ecologist Steve Seybold of the USDA Forest Service, Pacific Southwest Research Station, Davis, and an affiliate of the UC Davis Department of Entomology."Professor Francke has been a driving force in the field of chemical ecology for the last four decades, discovering countless new natural product chemicals of behavioral significance for animals and helping us to understand how plants and animals interact," said Seybold (left).
"Nearly everyone in the field has collaborated with him at some level; he has been a consummate mentor to younger chemical ecologists and has always been generous with his time, intellect, and chemical skills to everyone in that community," Seybold said. "He is remarkably brilliant in that he sees patterns in the make-up and synthesis of bio-organic compounds that most biologists, and even many chemists, may overlook."
Martha Stewart apparently does.
And the folks at the Bohart Museum of Entomology at the University of California, Davis, couldn't be happier.
See, the editors of Martha Stewart Living listed the Bohart insect collection kit as one of the top three gifts for the young naturalist.
How cool is that! Or, how buggy is that!
The Martha Stewart folks wrote on their website: “Here is a handful of gifts for the pint-size wildlife expert. If your child loves being outdoors and inspecting all things creepy-crawly, read on to find the perfect present."
They cautioned: "Just be sure to enforce a strict no-centipedes-indoors rule" before they head out with their "eco-cool contraptions!”
Museum director Lynn Kimsey (top), professor and former interim chair of the UC Davis Department of Entomology, has long known how fascinating bugs are--and now Martha apparently agrees.
Fact is, the Bohart Museum, located at 1124 Academic Surge on California Drive, is home to more than seven million insect specimens; a live "petting zoo" (think Madagascar hissing cockroaches and walking sticks); and a gift shop.
The gift shop is like an entomological candy shop. There you can buy bug-related posters, note cards, t-shirts, sweatshirts, jewelry, magnets, scorpion-encased lollipops....and yes...insect collection kits.
So if someone is bugging you about a holiday gift, check out the Bohart, either online or in person. To accommodate families who work during the week, the Bohart has scheduled a special weekend opening on Saturday, Dec. 11 from 1 to 4 p.m. The Bohart is traditionally open on weekdays, year around, from 8:30 a.m. to noon and from 1 to 5 p.m., Monday through Thursday.
We stopped at the Bohart Museum this morning and met a future entomologist who--yes--in his childhood owned an insect collection kit. Joel Hernandez, a UC Davis entomology major and a student assistant at the Bohart, acquired his kit at age 7. What first sparked his interest in entomology? An Animal Planet episode featuring the insects of Madagascar.
Hernandez later joined the Loma Vista 4-H Club, Ventura, and enrolled in an entomology project. His display of insects won "best of division" and "best of class" awards in the Ventura County Fair.
Hernandez now has five display cases of insects, including two cases of butterflies, one case of beetles and miscellaneous insects.
His ambition? To become an entomology professor.
Just think--somewhere out there is another "Joel" who will be getting his very own insect collection kit during the holidays--thanks to Martha.
Martha & Friends may now want to see the UC Davis Department of Entomology's video clips on "How to Make an Insect Collection." Professor James R. Carey taught the class last spring to undergraduates and graduate students. Their work can be viewed online.
Peter F. Billingsley (right), senior director of Entomology and Quality Systems at Sanaria Inc., Rockville, Md., will speak on "Development of a Mosquito-Derived, Attenuated Whole Parasite Vaccine against Malaria" on Friday, Dec. 3.
His talk--from 12:10 to 1 p.m. in the UC Davis Genome Center Auditorium, 1005 Genome and Biological Sciences Facility, 451 Health Sciences Drive--is part of the UC Davis Department of Medical Microbiology and Immunology Seminar Series, "Emerging Challenges in Microbiology and Immunology." It's also affiliated with the UC Davis Department of Entomology fall seminar series.
Host is Shirley Luckhart, associate professor of medical microbiology and immunology, who studies the malaria mosquito, Anopheles gambiae. Luckhart's many roles include serving as a graduate student advisor in the Department of Entomology.
Sanaria? It's a self-described "biotechnology company dedicated to the production of a vaccine protective against malaria caused by the pathogen Plasmodium falciparum."
Billingsley has more than 20 years experience in medical entomology and malaria transmission research. He directed research teams at Imperial College, London, and the University of Aberdeen, Scotland, examining diverse aspects of insect biology related to disease transmission, especially midgut and salivary gland biology, and more recently the molecular physiology of aging in mosquitoes.
Billinglsey, who earned his doctorate at Queen’s University in Canada, is a former head (chair) of zoology in the School of Biological Sciences, Aberdeen University.
Since 2006, he has devoted his broad expertise to the unique challenges of developing and deploying a live attenuated Plasmodium falciparum sporozoite vaccine at Sanaria Inc.
Billingsley's talk is generating a lot of interest, as well it should.
According to the Centers for Disease Control and Prevention (CDC), malaria kills more than a million people a year: "In 2008, an estimated 190 - 311 million cases of malaria occurred worldwide and 708,000 - 1,003,000 people died, most of them young children in sub-Saharan Africa."
