Apis Newsletter February 20, 2010




Dear Subscribers,

I find myself way behind this February of 2010.  A perfect storm of things has conspired to keep me from delivering this edition of the Apis Newsletter on time. right on the heels of the mega North American Beekeeping Conference in Orlando, I signed up to address the Southeast Organic Beekeepers event in Palm Beach County and the Georgia Beekeepers Association in Moultrie, GA.  Finally, I am in agreement with my friend Dr. Eric Mussen at the U of California, Davis says in his Nov/Dec 2009 newsletter From the  UC Apiaries, "I can't keep up" with all the information.  Now I'm trying to keep up with world  events through the Global Beekeeping Calendar.

On top of this has come the unexpected cold that seems to linger, including snow in Moultrie in south Georgia last weekend.  The maples and willows have  popped as is there habit in early February each year.  How much pollen the bees were able to get to begin population buildup is only a guess at present.  If they are like us humans, they will find themselves behind the eight ball; a lower population level for them, significantly inflated power bills for us.  On the other hand cold weather may shock the maples into secreting nectar and the citrus also.

No doubt this long cold spell and snowy winter adds fuel to global warming skeptics' arguments, but we have always taught in apiculture that averages are more important than local short-term events; thus photoperiod is what the plants and bees go by rather than localized temperature, but although more predictive in the long run, everyone can be caught short during extremes.  And it is the preponderance of extreme weather events that are on the climate change scientists' minds, rather than "global warming." 

The Southeast Organic event  was certainly different, featuring Sam Comfort, large-scale beekeeper turned small-scale advocate of top bar hives .  I have a running dialogue with the organizer of the Southeast event who wants "no scientists, just good beekeepers," the motto of last year's event.  There is something to be said, however, for hands-on activity rather than lecture, which includes offbeat ideas like manipulating honey bees at night and doing a "cut out" on site from a chest of drawers.  Also present was Beekeeper Linda Tillman from Atlanta, who described the event on her blog.This is a popular event; look for the third edition to be organized next year.

The Georgia meeting featured more scientists, including yours truly, Jennifer Berry and South carolina's Dr. Mike Hood.  The resurrection of Patsy cline at Rossman Apiaries during a snow event was surreal, but featured also down-to-earth fried fish and shrimp in classic Georgia style. 

I have a special place in my heart for Rossman Apiaries, where I started my short commercial beekeeping career and went on to write a series for The Speedy Bee on this experience  Linda Tillman was also there as I guessed the correct weight of a couple of set ups.  Don't ask me how.

Hunting for Bees:  We are excited to announce Bee Hunt, an opportunity for you and your group to participate in science research about the natural world.  Many of you already know about our Bee Hunt project, but some of you do not, and we want to get the word out far and wide... help us spread the word!  Bee Hunt is a project of Discover Life  (http://www.discoverlife.org). Discover Life provides unique online tools for studying natural history and tracking the impacts of ecological problems. We are building a network of study sites across North America and we’d like to invite you to participate!

There has been a great deal of discussion within the Florida State Beekeepers Association about food safety regulations.  Many small-scale bottlers find themselves with what they call an untenable financial burden.  Perhaps the best rundown on this issue is Dennis Riggs discussion on the Southwest Florida Association's web site.

Check out my February 2010 links at Publish2.com.  They include:  Apis cerana spread (big discussion on Bee-L about this), colony collapse disorder, bees as biocontrol of crows in Japan, Britian's train the trainer course, bees give warning of  danger, bees more efficient than cars, Phil Chandler The Barefoot Beekeeper and his podcasts, bees recognizing faces, old hive designs, and decline of bees in Europe,

Finally, check out Clint Walker's take on queen rearing and CCD.  This is a unique queen  producer perspective

Also make plans to attend the Brushy Mountain Webinar series.  The last one on urban beekeeping attracted a big buzz.

Central Beekeepers Alliance : Clarity on Honey Bee Collapse?

Central Beekeepers Alliance : Clarity on Honey Bee Collapse?


Clarity on Honey Bee Collapse?

Posted: 17 Feb 2010 05:00 AM PST

Beekeepers will be interested in highlights from an article published recently in Science magazine, called Clarity on Honey Bee Collapse?. It’s by Francis L. W. Ratnieks and Norman L. Carreck of the Laboratory of Apiculture and Social Insects, Department of Biological and Environmental Science, University of Sussex, UK.

Over the past few years, the media have frequently reported deaths of honey bee (Apis mellifera L.) colonies in the United States, Europe, and Japan. Most reports express opinions but little hard science.

It is not the mite itself that causes bee death, but a range of normally innocuous bee viruses that it carries.

A recent study of beekeeping history pointed out that extensive colony losses are have occurred at different points in time in many parts of the world. In other words, Colony Collapse Disorder is not the unique event that media attention would lead us to believe — and concern for honey bees has been “magnified by their vital role in agriculture” in the United States, where the $2-billion-per-year California almond industry depends on the pollination services of honey bees. Theories as to the cause of CCD have ranged from mobile phones and genetically modified crops (theories that were quickly dismissed by scientists) to more credible theories that have been the subject of more serious research: pests and diseases, environmental and economic factors, and pesticides.

Although full explanations for these losses are still debatable, the consensus seems to be that pests and pathogens are the single most important cause of colony losses.

There is also growing evidence that the ability of a particular pathogen to kill colonies may depend on other factors, such as the Varroa mire — but it’s not the mite itself that is killing bees, Ratnieks and Carreck point out, but the bee viruses that it carries and passes from one weakened, stressed honeybee to another.

Central Beekeepers Alliance : Suspect Named in Canadian Bee Losses

Central Beekeepers Alliance : Suspect Named in Canadian Bee Losses


Suspect Named in Canadian Bee Losses

Posted: 15 Feb 2010 05:00 AM PST

Bees across Canada have declined by 30 to 40 percent every spring since 2006, and the numbers are similar across the northern hemisphere. It may come as a surprise to struggling beekeepers, then, that University of Guelph entomological researcher Dr. Ernesto Guzman says Colony Collapse Disorder may not even exist.

In the past two years alone, hundreds of books have been published on the plight of domestic honeybees.

“CCD is an arbitrary name,” Dr. Guzman told the Toronto Star, “designed by U.S. scientists to define a high mortality of colonies that have no explainable reason… Radio waves, even terrorist plots” are among some of the theories.

Certainly, what’s going on in Canada is not the same as what’s been happening in the United States — our bees are not actually disappearing. And that’s the main symptom of CCD cases, that beekeepers don’t find dead bees in the hive. “It’s like they have died in the field and they never came back,” Dr. Guzman says.

“We don’t see that in Canada, I believe, because in the winter they cannot fly out.”

Instead, Canadian beekeepers tend to find piles of dead bees in the bottom of hives when they open them up in the spring.

What's been killing off our Canadian honeybees?
Varroa mites are strongly suspected.

Heartbreaking for beekeepers, but those sad little corpses actually turn out to be a good thing for us, however — it means that Canadian bee researchers have something to study! And Guzman’s been doing just that. He followed 413 Ontario bee colonies for a year and took a close-up look at the 27 percent of those hives that didn’t make it through the winter.

In a forthcoming report in the journal Apidologie, Guzman blames the varroa mite — that tiny crab-like parasite that sucks the blood out of bees, hopelessly weakening them so even if they aren’t killed outright they become more susceptible to disease –in combination with poor bee populations and low food reserves going into the winter.

Central Beekeepers Alliance : Automatic Beekeeping?

Central Beekeepers Alliance : Automatic Beekeeping?


Automatic Beekeeping?

Posted: 12 Feb 2010 08:18 AM PST

“Automatic hive – no beekeeper needed!” That’s what the man says, and offers an online manual with “detailed instructions for constructing and operating fully automatic hives, for which no bee knowledge is required of any kind, since only open to harvest.”

I’m not sure if this method of beekeeping is (a) legal or (b) wise, in this part of the world — but the theory is certainly sure to get beekeepers thinking and talking!

The website that explains this system is Apicultura Extensiva Natural by Oscar Perone, a professional beekeeper since 2002 and teacher of beekeeping at a college in Buenos Aires, Argentina. The photographs and diagrams are interesting in themselves, and Google will give you an English translation to read to get the details.

CATCH THE BUZZ - Really, Bees on Nicotine & Caffeine?

CATCH THE BUZZ

Are bees also addicted to caffeine and nicotine?

A study carried out at the University of Haifa has found that bees prefer nectar with a small concentration of caffeine and nicotine over nectar that does not comprise these substances at all

Bees prefer nectar with small amounts of nicotine and caffeine over nectar that does not comprise these substances at all, a study from the University of Haifa reveals. "This could be an evolutionary development intended, as in humans, to make the bee addicted," states Prof. Ido Izhaki, one of the researchers who conducted the study.

Flower nectar is primarily comprised of sugars, which provide energy for the potential pollinators. But the floral nectar of some plant species also includes small quantities of substances known to be toxic, such as caffeine and nicotine. The present study, carried out by researchers at the Department of Environmental and Evolutionary Biology and the Department of Science Education at the University of Haifa-Oranim, headed by Prof. Ido Izhaki along with Prof. Gidi Ne'eman, Prof. Moshe Inbar and Dr. Natarajan Singaravelan, examined whether these substances are intended to "entice" the bees or whether they are byproducts that are not necessarily linked to any such objective.

Nicotine is found naturally in floral nectar at a concentration of up to 2.5 milligrams per liter, primarily in various types of tobacco tree (Nicotiana glauca). Caffeine is found at concentration levels of 11-17.5 milligrams per liter, mostly in citrus flowers. In the nectar of grapefruit flowers, however, caffeine is present in much higher concentrations, reaching 94.2 milligrams per liter. In order to examine whether bees prefer the nectar containing caffeine and nicotine, the researchers offered artificial nectar that comprised various natural sugar levels and various levels of caffeine and nicotine, alongside "clean" nectar that comprised sugar alone. The caffeine and nicotine concentrations ranged from the natural levels in floral nectar up to much higher concentrations than found in nature.

The results showed that bees clearly prefer nectar containing nicotine and caffeine over the "clean" nectar. The preferred nicotine concentration was 1 milligram per liter, similar to that found in nature. Given a choice of higher levels of nicotine versus "clean" nectar, the bees preferred the latter.

According to the researchers, it is difficult to determine for sure whether the addictive substances in the nectar became present in an evolutionary process in order to make pollination more efficient. It can be assumed, however, based on the results of the study, that the plants that survived natural selection are those that developed "correct" levels of these addictive substances, enabling them to attract and not repel bees, thereby giving them a significant advantage over other plants. The researchers emphasized that this study has proved a preference, not addiction, and they are currently examining whether the bees do indeed become addicted to nicotine and caffeine.
