Survey Reports Latest Honey Bee Losses / April 29, 2010 / News from the USDA Agricultural Research Service
Survey Reports Latest Honey Bee LossesBy Kim KaplanApril 29, 2010 Losses of managed honey bee colonies nationwide totaled 33.8 percent from all causes from October 2009 to April 2010, according to a survey conducted by the Apiary Inspectors of America(AIA) and the Agricultural Research Service (ARS). Beekeepers identified starvation, poor weather, and weak colonies going into winter as the top reasons for mortality in their operations. This is an increase from overall losses of 29 percent reported from a similar survey covering the winter of 2008-2009, and similar to the 35.8 percent losses for the winter of 2007-2008. The continued high rate of losses are worrying, especially considering losses occurring over the summer months were not being captured, notesJeffrey Pettis, research leader of ARS' Bee Research Laboratory in Beltsville, Md. ARS is theU.S. Department of Agriculture's principal intramural scientific research agency. The survey was conducted by Pettis and past AIA presidents Dennis vanEngelsdorp and Jerry Hayes. The three researchers said that continued losses of this magnitude are not economically sustainable for commercial beekeepers. The 28 percent of beekeeping operations that reported some of their colonies perished without dead bees present—a sign of Colony Collapse Disorder (CCD)—lost 44 percent of their colonies. This compares to 26 percent of beekeepers reporting such dead colonies in the 2008-2009 winter and 32 percent in the 2007-2008 winter. Beekeepers that did not report their colonies having CCD lost 25 percent of their colonies. As this was an interview-based survey, it was not possible to differentiate between verifiable cases of CCD and colonies lost as the result of other causes that share the "absence of dead bees" as a symptom. The cause of CCD is still unknown. The survey checked on about 22.4 percent of the country's estimated 2.46 million colonies. The survey reports only winter losses and does not capture colony losses that occur throughout the summer when queens or entire colonies fail and need to be replaced. Those summer losses can be significant. A complete analysis of the survey data will be published later this year.

120,000 honeybees buzz atop Ritz-Carlton
bhenderson@charlotteobserver.com
MORE INFORMATION
The penthouse roof of one of uptown Charlotte's swankiest hotels buzzed with activity Wednesday as its 120,000 new residents, honeybees, met their public.
On the eve of Earth Day, the Ritz-Carlton unveiled its new green roof, planted with a groundcover called sedum. Tomatoes, herbs and lavender grow in raised beds on one side. On the other stand two handsome beehives, painted white with copper roofs.
The bees will become urban commuters, visiting condo balconies and city parks in a two-mile radius before returning to their 18th-floor base. Their honey will flavor the hotel's yogurt, granola and brews served at high tea, said executive chef Jon Farace.
"I think we'll just have to categorize it as a wildflower honey," said Randall York of Cloister Honey, which tends the hives. "It should be just a good floral mix."
It's all in keeping with the hotel's environmental ethos.
On Wednesday the hotel became the first Ritz-Carlton to win a green stamp of approval from the U.S. Green Building Council, LEED (Leadership in Energy and Environmental Design) Gold designation. The hotel hopes to win a similar label for its operating practices.
Only 50 hotels have earned the LEED label, Rick Fedrizzi, chief executive of the Green Building Council, said.
Bank of America, which built the hotel, announced a $20 billion, 10-year environmental initiative in 2007. The bank's new tower in Manhattan earned LEED Platinum, the highest rank for green design.
Here, a Ritz-Carlton employee will adopt the persona of Mother Nature, tucking in kids staying at the hotel, giving eco-tours, appearing at local events.
But York said he knows of no other rooftop hives uptown.

ARS : Questions and Answers: Colony Collapse Disorder
Questions and Answers: Colony Collapse Disorder |
Beginning in October 2006, some beekeepers began reporting losses of 30-90 percent of their hives. While colony losses are not unexpected during winter weather, the magnitude of loss suffered by some beekeepers was highly unusual. This phenomenon, which currently does not have a recognizable underlying cause, has been termed "Colony Collapse Disorder" (CCD). The main symptom of CCD is simply no or a low number of adult honey bees present but with a live queen and no dead honey bees in the hive. Often there is still honey in the hive, and immature bees (brood) are present. ARS scientists and others are in the process of carrying out research to discover the cause(s) of CCD and develop ways for beekeepers to respond to the problem. Why should the public care about honey bees? Bee pollination is responsible for $15 billion in added crop value, particularly for specialty crops such as almonds and other nuts, berries, fruits, and vegetables. About one mouthful in three in the diet directly or indirectly benefits from honey bee pollination. While there are native pollinators (honey bees came from the Old World with European colonists), honey bees are more prolific and the easiest to manage for the large scale pollination that U.S. agriculture requires. In California, the almond crop alone uses 1.3 million colonies of bees, approximately one half of all honey bees in the United States, and this need is projected to grow to 1.5 million colonies by 2010.
The number of managed honey bee colonies has dropped from 5 million in the1940s to only 2.5 million today. At the same time, the call for hives to supply pollination service has continued to climb. This means honey bee colonies are trucked farther and more often than ever before. Honey bee colony health has also been declining since the 1980s with the advent of new pathogens and pests. The spread into the United States of varroa and tracheal mites, in particular, created major new stresses on honey bees. Is there currently a crisis in food production because of CCD? While CCD has created a very serious problem for beekeepers and could threaten the pollination industry if it becomes more widespread, fortunately there were enough bees to supply all the needed pollination this past spring. But we cannot wait to see if CCD becomes an agricultural crisis to do the needed research into the cause and treatment for CCD. The cost of hives for pollination has risen this year. But much of that is due to growing demand. Some of the price increase may also be due to higher cost of gas and diesel and other increases related to energy and labor costs. Commercial beekeepers truck hives long distances to provide pollination services, so in particular they must deal with rising expenses. Are there any theories about what may be causing CCD? Case studies and questionnaires related to management practices and environmental factors have identified a few common factors shared by those beekeepers experiencing CCD, but no common environmental agents or chemicals stand out as causative. There are three major possibilities that are being looked into by researchers. Pesticides may be having unexpected negative effects on honey bees. A new parasite or pathogen may be attacking honey bees. One possible candidate being looked at is a pathogenic gut microbe called Nosema. Viruses are also suspected. A perfect storm of existing stresses may have unexpectedly weakened colonies leading to collapse. Stress, in general, compromises the immune system of bees (and other social insects) and may disrupt their social system, making colonies more susceptible to disease. These stresses could include high levels of infection by the varroa mite (a parasite that feeds on bee blood and transmits bee viruses); poor nutrition due to apiary overcrowding, pollination of crops with low nutritional value, or pollen or nectar scarcity; and exposure to limited or contaminated water supplies. Migratory stress brought about by increased needs for pollination might also be a contributing factor.
Has CCD ever happened before? The scientific literature has several mentions of honey bee disappearances—in the 1880s, the 1920s and the 1960s. While the descriptions sound similar to CCD, there is no way to know for sure if the problems were caused by the same agents as today's CCD. There have also been unusual colony losses before. In 1903, in the Cache Valley in Utah, 2000 colonies were lost to an unknown "disappearing disease" after a "hard winter and a cold spring." More recently, in 1995-96, Pennsylvania beekeepers lost 53 percent of their colonies without a specific identifiable cause.
What about cell phones—do they have anything to do with CCD? The short answer is no. There was a very small study done in Germany that looked at whether a particular type of base station for cordless phones could affect honey bee homing systems. But, despite all the attention that this study has received, it has nothing to do with CCD. Stefan Kimmel, the researcher who conducted the study and wrote the paper, recently e-mailed The Associated Press to say that there is "no link between our tiny little study and the CCD-phenomenon ... anything else said or written is a lie." What is ARS doing about CCD? In April 2007, ARS held a Colony Collapse Disorder Research Workshop that brought together over 80 of the major bee scientists, industry representatives, extension agents, and others to discuss a research agenda. They identified areas where more information is needed and the highest-priority needs for additional research projects related to CCD. A CCD Steering Committee, led by ARS and USDA's Cooperative State Research, Education, and Extension Service, developed a Research Action Plan to coordinate a comprehensive response for discovering what factors may be causing CCD and what actions need to be taken. One of the tools that will help in this research is the recently sequenced honey bee genome to better understand bees' basic biology and breed better bees, and to better diagnose bee pests and pathogens and their impacts on bee health and colony collapse. The use of this genome information certainly will have great applications in improving honey bee breeding and management.
The search for factors that are involved in CCD is focusing on four areas: pathogens, parasites, environmental stresses, and bee management stresses such as poor nutrition. It is unlikely that a single factor is the cause of CCD; it is more likely that there is a complex of different components. In September 2007, a research team that included ARS published the results of an intensive genetic screening of CCD-affected honey bee colonies and non-CCD-affected hives. The only pathogen found in almost all samples from honey bee colonies with CCD, but not in non-CCD colonies, was the Israeli acute paralysis virus (IAPV), a dicistrovirus that can be transmitted by the varroa mite. It was found in 96.1 percent of the CCD-bee samples. This research does not identify IAPV as the cause of CCD. What this research found was strictly a strong correlation of the appearance of IAPV and CCD together. No cause-and-effect connection can be inferred from the genetic screening data. (More information about this study) This was the first report of IAPV in the United States. IAPV was initially identified in honey bee colonies in Israel in 2002, where the honey bees exhibited unusual behavior, such as twitching wings outside the hive and a loss of worker bee populations. The study also found IAPV in honey bees from Australia that had been imported into the United States, as well as in royal jelly imported from China. Australian bees began to be imported from Australia into the United States in 2005. Questions were raised about a connection between those imported bees and the appearance of IAPV in the United States. Beekeepers sought out Australian imports of bees as a way to replenish their hive populations. To determine whether IAPV has been present in the United States since before the importation of honey bees from Australia, a follow up detailed genetic screening of several hundred honey bees that had been collected between 2002 and 2007 from colonies in Maryland, Pennsylvania, California and Israel was conducted by ARS researchers. The results of the follow study showed IAPV has been in this country since at least 2002, which challenges the idea that IAPV is a recent introduction from Australia. (More information about this study)
This study in no way rules IAPV out as a factor in CCD. Research by several groups will now focus on understanding differences in virulence across strains of IAPV and on interactions with other stress factors. Even if IAPV proves to be a cause of CCD, there still may also be other contributing factors-which researchers are pursuing. What should beekeepers do now about CCD? Since little is known about the cause(s) of CCD right now, mitigation must be based on improving general honey bee health and habitat and countering known mortality factors by using best management practices. What can I as a member of the public do to help honey bees? The best action you can take to benefit honey bees is to not use pesticides indiscriminately, especially not to use pesticides at mid-day when honey bees are most likely to be out foraging for nectar. In addition, you can plant and encourage the planting of good nectar sources such as red clover, foxglove, bee balm, and joe-pye weed. For more information, see www.nappc.org.] |
Bee Colony Collapse May Have Several Causes | Wired Science | Wired.com
Bee Colony Collapse May Have Several Causes
When suspiciously large numbers of honeybee colonies started collapsing in late 2006, the search began to find the culprit behind the mysterious deaths. Now it seems a whole web of problems may be causing what’s known as colony collapse disorder.
It’s becoming clear that there is no single parasite, virus or chemical to blame, argues Frances Ratnieks, a bee scientist at University of Sussex in Brighton.
Instead, honeybees are probably dying for all kinds of different reasons from loss of their foraging grounds to increased exposure to global pathogens, Ratnieks wrote in a review of the issue in the journal Science.
“We may conclude that colonies are dying for different reasons in different parts of the world and I would say that if that is the case, I would not be the least bit surprised,” Ratnieks told Wired.com.
A variety of pests, viruses and parasites could all be working together to stress the bees. And in some ways, that’s worse than trying to take on a single culprit: The problems with beekeeping are systemic, Ratnieks said, and can’t be solved with a new pesticide or technique.
In an increasingly globalized world, bee pathogens travel quickly between bee populations. Over the last decades, the Varroa destructor mite has spread from Asian honeybees to the rest of the continents. The gut parasite Nosema ceranae has taken the same path. Both species are believed to make existing bee diseases worse. V. destructor took about four decades, reaching North America about a decade ago. N. ceranae circled the globe in a quarter of that time.
“It is certainly a case in the modern world, pathogens can be transmitted from one corner of the world to an another quickly,” Ratnieks said.
He compared the bee pathogen problems to those humans are encountering with swine flu and other emerging diseases, which can spread quickly thanks to modern transportation.
“Even though the U.S. is a big country, what shows up in one part of the country shows up in the other parts of the county in no-time flat,” he said.
That’s in part because of the economics of beekeeping. The $2 billion almond crop in California requires 1,000,000 honeybee hives for cross-pollination. That’s more than 40 percent of all the beehives in the country. So, come almond-tree flowering season, which begins in February, apiarists load up their hives on flatbeds and truck them to San Joaquin Valley. While this pilgrimage may be necessary to keep churning out cheap almonds, it also creates a melting pot of pathogens. And the moving and trucking itself could negatively impact the bees, too.
Ratnieks also suspects that honeybees are more susceptible to disease because their natural forage — weeds and gardens, etc. — has been wiped out by single-crop farming in the major farming valleys of the country.
Add it all up and the honeybees are fighting the battle to survive on several, interconnected fronts.
“It’s harder to keep a hive alive now. It used to be with bees in America, if the hive was alive and thriving, chances are the hive would be alive and thriving the next year,” said Ratnieks. “Now, they are feeding their hives with supplements and feeding them with chemicals, they are having to peddle pedal quite hard just to keep their hives alive.”
Last year, there were enough honeybees to keep the almond trees pollinated, but last summer’s weather conditions were bad in North Dakota and the neighboring states where the California hives often spend the season.
With the big almond flowering coming up, and the bees in bad condition, the beginning of next month could harbor a nasty surprise for nut farmers.
“In early February, that’s when the rubber hits the road or the shit hits the fan,” Ratnieks concluded.

Bees Throw Out Mites
Bees Throw Out Mites
September 11, 2009 By Alfredo FloresVarroa-sensitive hygiene (VSH) is a genetic trait of the honey bee that allows it to remove mite-infested pupae from the capped brood—developing bees that are sealed inside cells of the comb with a protective layer of wax. The mites are sometimes difficult for the bees to locate, since they attack the bee brood while these developing bees are inside the capped cells.
To test the varroa resistance of VSH bees, the Baton Rouge team conducted field trials using 40 colonies with varying levels of VSH. Mite population growth was significantly lower in VSH and hybrid colonies than in bee colonies without VSH. Hybrid colonies had half the VSH genes normally found in pure VSH bees, but they still retained significant varroa resistance. Simpler ways for bee breeders to measure VSH behavior in colonies were also developed in this study.
This research was published in the Journal of Apicultural Research and Bee World.

Honeybee Decline Slows Slightly
Discovery Reports:
May 20, 2009 -- The decline of honeybee colonies has slowed slightly since last fall, but a mysterious combination of ailments is still decimating the insect's population, federal researchers say.
U.S. Department of Agriculture researchers found that honeybee colonies declined by 29 percent between September 2008 and early April. That's an improvement over the last two years, when researchers found that 32 percent and 36 percent of all beekeepers surveyed lost hives.
Domestic honeybee stocks have been waning since 2004 because of a puzzling illness scientists called colony collapse disorder, which causes adult bees to inexplicably forsake their broods. Bees now appear also to be suffering from other ailments.
Honeybees help pollinate many fruits and vegetables, including blueberries, tomatoes, apples and almonds.
The disorder has killed off the weakest colonies in recent years, and now pesticide drift and old foes such as the parasitic varroa mite are more likely threatening those that survived, said Jerry Hayes, a former president of the Apiary Inspectors of America, whose members helped carry out the survey.
"Whether it's CCD or pesticides, fungicides or chemicals affecting how the queens respond, I don't know that beekeepers care," said Hayes, chief of the apiary sector of the Florida Department of Agriculture. "The ones who I talk to are just beside themselves. If you are a small business person how many years of 30 percent losses can you take?"
Regardless of the cause, bees are still dying at rates that could put some keepers out of business, said Jeff Pettis, the USDA's top bee scientist.
The survey released Tuesday included 787 beekeepers who account for 20 percent of the country's approximately 2.3 million commercially managed bee hives. The data -- collected through a spring telephone survey in which researchers polled keepers about how many of their hives survived the fall and winter, when queens go dormant -- is being prepared for submission to a journal.

A Comparison of Russian and Italian
Russian and Italian
Honey Bees
American beekeepers have been using Italian honey bees (Apis
mellifera ligustica) since they were first imported to the New World in
1859. The standard German honey bee (A. m. mellifera), which had
been in America for more than 200 years, was by that time ill-tempered,
disease-ridden, and less suited for honey bee management. Conversely,
the Italian bees were and are excellent honey producers, show a gentle
temperament that makes them the most popular race of honey bee in
North America, have a moderately low tendency to swarm, and have a
bright yellow color that makes queens easy to find.

to two deadly parasitic mites,
the tracheal mite (Acarapis woodi) and
the varroa mite (Varroa destructor),
which were introduced into the U.S. in
1984 and 1987, respectively. Colonies
contract these mites through equipment
sharing and overcrowding, and, once
infested, entire colonies can succumb
within one or two years. Beekeepers
have relied largely on pesticides to
control the mites, but many of these
chemicals can contaminate the honey
and beeswax in a hive. The mites also
are becoming increasingly resistant to
the pesticides, making the chemicals
less reliable and, eventually, ineffective.
The high colony mortality that accompanies
these two mites is a serious
concern of the bee industry today, and
various types of bees are continually
being examined with an eye toward
finding a hardy, productive stock that
can resist them.
B
Russian Bee Project
Efforts to find a honey bee that is genetically resistant to
the varroa and tracheal mites led researchers at the USDA
Honey Bee Research Laboratory in Baton Rouge, Louisiana,
to Russia. There, on the far eastern side of that vast
nation, in the coastal Primorski region around Vladivostok,
they found what they sought—a promising strain of Apis
mellifera. These Russian bees had been exposed to varroa
mites for approximately 150 years, much longer than other
Apis mellifera strains had, and the researchers surmised
that the Russian bees could have developed a resistance
to the mites. Indeed, subsequent research has shown that
these Russian bees are more than twice as resistant to varroa
mites than other honey bees. Moreover, they are highly
resistant to tracheal mites, the other mortal enemy of bees.
Russian bees also tend to produce as much honey as standard
bee stocks, if not more.
A number of American queen breeders now produce Russian
queens for sale. These breeders are located all across
the country, but most are concentrated in the South and in
California. Many of the Russian queens on the market are
hybrid daughters of a breeder queen openly mated to any
drone, which may come from a variety of stocks within
two miles of a particular mating yard. The resulting colonies
are genetic hybrids. Recent research has suggested the
hybrids are only partially resistant to mites, but studies at
North Carolina State University show that partial resistance
is statistically significant when the hybrids are compared to
Italian bees.
Production of pure Russian queens can be guaranteed only
by truly isolating the breeding grounds, as has been done at
the USDA’s bee laboratory on Grand Terre Island, 25 miles
off the coast of Louisiana. Here the drone stock is also
controlled.
Management of Russian bees
Russian bees are quite different from standard Italian bees
in several ways (Table 1):
• Russian bees do not build their colony populations
until pollen is available, and they shut down brood
rearing when pollen is scarce. This characteristic
makes them suitable in areas where the main honey
and pollen flows occur later in the year, such as the
mountains of North Carolina. By contrast, Italian bees
maintain a large brood area and worker population
regardless of environmental conditions. This trait can
result in more bees than the hive can feed and may
lead Italian colonies to early winter starvation. It also
explains the Italian bee’s tendency to rob other colonies
of their honey stores.
• Russian colonies maintain active queen cells through
out the brood-rearing season. In Italian colonies, the
presence of queen cells is interpreted by beekeepers
as an attempt to swarm (reduce overcrowding by
establishing a new colony) or to supersede (kill and
replace) the resident queen. This is not the case with
Russian colonies, as the workers often destroy the
extra queen cells before they fully develop.
• Russian bees can vary in color, but they are generally
darker than the Italians.
Requeening Italian hives with Russian queens can be difficult,
and many beekeepers lose their newly introduced Russian
queens. Russian queens have a different “odor” than
Italians, and parent colonies must become acclimated to
this odor before they will accept the newcomers. Beekeepers
who intend to go from Italian to Russian bees should
requeen a colony in the fall by splitting the hive in two with
the use of a double screen (see highlighted information).
This will permit the odors to mix but, at the same time,
prevent the workers from interacting with the new queen.
The old Italian queen should be kept in the lower half, and
the new Russian queen should be placed in the upper half
in a cage. If a separate entrance is provided to the upper
half, only young nurse bees will enter the top portion, and
the older foraging bees will return to the lower hive.
Table 1. A comparison of various colony characteristics of Italian and Russian honey bees
Characteristic Italians Russians
Varroa mites More susceptible More resistant
Tracheal mites More susceptible Highly resistant
Brood rearing Continuous throughout the summer Usually only during times of pollen availability
Robbing High Low
Queen cells Only during swarming or queen replacement Present most of the time
Pollination skills Small difference from Russian bees Small difference from Italian bees
Temperament Gentle, less defensive; not likely to sting Gentle, less defensive; not likely to sting
Color Light Dark
The Russian queen should be released from her cage after
seven to ten days and permitted to lay eggs for four weeks.
During this time, the odor of the Russian queen will comingle
with that of the Italian colony. If the Russian queen
continues to lay eggs and is being tended by the workers,
she has been accepted. After this acclimation period,
the Italian queen can be removed, and the colony can be
reunited. If the workers do not accept the new queen during
the four weeks of acclimation, the requeening process has
failed, and the workers kill her. But the colony will still
have the original Italian queen, and the entire hive will not
be lost.
Hybrid bees tend to lose their initial desirable traits over
subsequent generations. Because many commercial Russian
bees are hybrids, the queen should be marked with
paint to distinguish them from succeeding generations.
If the colony contains an unmarked queen, she is probably
homegrown and a second-generation hybrid and should be
replaced with a new marked Russian queen as soon as
possible to preserve the hive’s resistance to the mites.
When requeening a Russian colony with a Russian queen,
it probably will not be necessary to use the extended acclimation
period outlined above. Queens usually come in
the mail in cages made of wood and wire-mesh. The exit
hole is blocked with a hard candy-like substance that the
bees must eat through to release the queen. This usually
takes several days, after which the queen has acquired the
colony “odor” and is readily accepted by the workers. As
noted above, requeening an Italian honey bee colony with a
Russian queen takes longer because of the Russian queen’s
very different odor.
Conclusion
Russian honey bees can be a valuable tool in controlling
the depredations of varroa and tracheal mites and also in
reducing, but not necessarily eliminating, the need for
chemical treatments to control these mites. However, the
beekeeper must understand how to manage bees of this
new stock properly, as they are quite different from the
widely used Italian honey bees.

Requeening Italian colonies with Russian queens
The requeening procedure has frustrated many beekeepers because standard introduction techniques often
are not successful when requeening Italian colonies with Russian queens, as the colonies may reject the new
queens. Italian bee colonies need more time and separation to become acclimated to Russian queens.
Step 1: Split the colony in half, with the two halves separated by a double screen.
Step 2: Place the old queen in the bottom half and a caged Russian queen in the upper half.
Step 3: Release the Russian queen from her cage after 7 to 10 days.
Step 4: Once the Russian queen has been accepted and has laid eggs for one month, kill the old queen,
and reunite the two halves (remove the screens).
