Recent Honey Bee Colony Declines
Summary
This report examines the recent sharp decline in U.S. honey bee colonies, which
scientists are now calling the Colony Collapse Disorder (CCD). This phenomenon
first became apparent among commercial migratory beekeepers along the East Coast
during the last few months of 2006, and has since been reported nationwide.
Honey bees are the most economically valuable pollinators of agricultural crops
worldwide. Many scientists at universities and the U.S. Department of Agriculture
(USDA) frequently assert that bee pollination is involved in about one-third of the
U.S. diet, and contributes to the production of a wide range of fruits, vegetables, tree
nuts, forage crops, some field crops, and other specialty crops. The monetary value
of honey bees as commercial pollinators in the United States is estimated at about
$15 billion annually.
Honey bee colony losses are not uncommon. However, current losses seem to
differ from past situations in that
! colony losses are occurring mostly because bees are failing to return
to the hive (which is largely uncharacteristic of bee behavior),
! bee colony losses have been rapid,
! colony losses are occurring in large numbers, and
! the reason why these losses are occurring remains still largely
unknown.
To date, the potential causes of CCD, as reported by the scientists who are
researching this phenomenon, include but may not be limited to
! parasites, mites, and disease loads in the bees and brood;
! known/unknown pathogens;
! poor nutrition among adult bees;
! level of stress in adult bees (e.g., transportation and confinement of
bees, or other environmental or biological stressors);
! chemical residue/contamination in the wax, food stores and/or bees;
! lack of genetic diversity and lineage of bees; and
! a combination of several factors.
On March 29, 2007, the House Subcommittee on Horticulture and Organic
Agriculture is to hold a hearing to review the recent honey bee colony declines
reported throughout the United States. Based on information presented to Congress,
both by scientists researching recent bee colony declines and by agricultural
producers who may be potentially affected by these losses, Congress could consider
options for subsequent action in this area.
This report will be updated after the House Subcommittee hearing to report
additional information from the hearing and possible congressional response to this
current situation.

Recent Honey Bee Colony Declines
This report examines the recent sharp decline in U.S. honey bee colonies, or the
so-called Colony Collapse Disorder (CCD). This phenomenon first became apparent
among commercial migratory beekeepers along the East Coast during the last few
months of 2006 and has since been reported nationwide.
This report is organized in three parts. First, it provides an overview of the
importance of honey bee pollination to U.S. agricultural production, especially
specialty crops. Second, it describes the extent and symptoms of CCD and how it
differs from previous honey bee colony losses. Third, it discusses some of the
reasons why scientists believe honey bee colonies are being affected by CCD.
On March 29, 2007, the House Subcommittee on Horticulture and Organic
Agriculture is to hold a hearing to review the recent honey bee colony declines.
Based on information presented to Congress, both by scientists researching recent bee
colony declines and by agricultural producers who may be potentially affected by
these losses, Congress could consider options for subsequent legislative action in this
area. This report will be updated to reflect the activities at the hearing.
Importance of Honey Bee Pollination
Honey bees (genus Apis) are the most economically valuable pollinators of
agricultural crops worldwide.1 In the United States, bee pollination of agricultural
crops is said to account for about one-third of the U.S. diet, and contribute to the
production of a wide range of fruits, vegetables, tree nuts, forage crops, some field
crops, and other specialty crops.2
The monetary value of honey bees as commercial pollinators in the United
States is estimated at about $15 billion annually3 (Table 1). This estimated value is
measured according to the additional value of production attributable to honey bees,
in terms of the value of the increased yield and quality achieved from honey bee
1 Some other known animal pollinators are stingless bees, bumble bees, and other bees;
wasps, hover flies and other flies; beetles; thrips; ants; butterflies; moths; bats; and
hummingbirds and other birds.

not rely on insect pollination and are mostly wind pollinated.

pollination, including the indirect benefits of bee pollination required for seed
production of some crops. About one-third of the estimated value of commercial
honey bee pollination is in alfalfa production, mostly for alfalfa hay. Another nearly
10% of the value of honey bee pollination is for apples, followed by 6-7% of the
value each for almonds, citrus, cotton, and soybeans.
A number of agricultural crops are almost totally dependent on honey bee
pollination (90-100%), including almonds, apples, avocados, blueberries, cranberries,
cherries, kiwi fruit, macadamia nuts, asparagus, broccoli, carrots, cauliflower, celery,
cucumbers, onions, legume seeds, pumpkins, squash, and sunflowers. Other
specialty crops also rely on honey bee pollination, but to a lesser degree. These crops
include apricot, citrus (oranges, lemons, limes, grapefruit, tangerines, etc.), peaches,
pears, nectarines, plums, grapes, brambleberries, strawberries, olives, melon
(cantaloupe, watermelon, and honeydew), peanuts, cotton, soybeans, and sugarbeets.4
Another study found that pollinators are essential for the production of some U.S.-
grown crops, particularly macadamia nuts, squash, and pumpkins.5
In the United States, most pollination services are provided by commercial
migratory beekeepers who travel from state to state and provide pollination services
to crop producers. These operations are able to supply a large number of bee
colonies during the critical phase of a crop’s bloom cycle, when honey bees pollinate
a crop as they fly from flower to flower collecting nectar and pollen, which they carry
back to the nest.6 The latest Census of Agriculture by the U.S. Department of
Agriculture (USDA) reports that there were about 17,000 operations with 2.4 million
bee colonies in 2002.7 The majority of these, more than 2 million bee colonies, are
reported to belong to commercial migratory beekeepers. About one-third of all
colonies are in California (about 20%) and Florida (10%). The Dakotas accounted
for another 7% each of all bee colonies, and Texas and Montana accounted for
another 5% each. Other states with a large number of bee colonies were Minnesota,
Idaho, Michigan, Washington, Wisconsin, Oregon, and New York, which together
accounted for about 20%. While these operations also produce honey for commercial
sale, it is their value as crop pollinators that provides the greatest economic impact
in the production of food and feed crops.

commercial hives.

Each year, an estimated more than 2 million bee colonies are rented for U.S.
crop pollination. Available limited information indicates that the greatest number of
honey bee colony rentals are for apple and almond production, followed by clover
seed, cherries, and pears.8 Rental fees collected by commercial beekeepers for
pollination services may vary by crop type, and often tend to be lower for some seed
crops and higher for berry and tree crops. In recent years, pollination fees paid by
crop producers have increased. For example, fees paid by California’s almond
industry have risen from a reported $35 per colony in the late 1990s to about $75 per
colony in 2005.9 More recent estimates of fees for pollinating almond trees are even
higher, at $150 per colony or more. Among the reasons for higher pollination fees
are expanding almond acreage and relatively high honey prices, but also fewer
available honey bees for pollination due, in part, to colony declines and bee
mortalities. About 1.4 million colonies of honey bees are used to pollinate
California’s current 550,000 acres of almond trees.
Extent and Symptoms of Colony Collapse Disorder
Starting in the last three months of 2006, a seemingly new phenomenon began
to occur based on reports of an “alarming” number of bee colony losses and die-off
along the East Coast. By the end of 2006, beekeepers on the West Coast also began
to report “unprecedented” losses.10 Because of the severity and lack of precedent,
scientists coined a new term, Colony Collapse Disorder (CCD), for this phenomenon.
Much of the current research on CCD is being conducted by scientists at
Pennsylvania State University, University of Montana, USDA’s Agriculture Research
Service (Beltsville bee laboratory), and the Pennsylvania and Florida Departments
of Agriculture. Many of these researchers also participate in the CCD Working
Group, which includes Bee Alert Inc., the Florida and Pennsylvania Departments of
Agriculture, Pennsylvania State University, and USDA. Up-to-date information is
regularly posted to the website of the Mid-Atlantic Apiculture Research and
Extension Consortium (MAAREC), which represents beekeeping associations in
New Jersey, Maryland, Delaware, Pennsylvania, and West Virginia.
Past Honey Bee Population Losses
Honey bee colony losses are not uncommon. A recent report by the National
Research Council (NRC) documents the extensive literature on honey bee population
losses due to bee pests, parasites, pathogens, and disease. Most notable are declines
due to two parasitic mites, the Varroa destructor and the tracheal mite (Acarapis

woodi), and also colony declines due to the pathogen Paenibacillus larvae.11 Other
reasons for bee colony declines reported by the NRC include interspecific
competition between native and introduced bees, pathogen spillover effects, habitat
loss, invasive plant species that reduce nectar- and pollen-producing vegetation, bee
genetics, and pesticides, among other factors.
Mite infestations are a relatively new occurrence. The 1980s saw two periods
of large die-offs due to Varroa and tracheal mites: The first Varroa mite infestation
was reported in 1987; tracheal mites were first detected in 1984.12 Varroa mites are
also said to have eliminated most feral bee colonies in the mid-1990s.13 Varroa
parasitism affects both worker bees and male larvae and can affect the ability of the
queen to reproduce. It is associated with viral pathogens and if left untreated can
cause colony mortalities usually within six months to two years after the initial
infestation. Less is known about the effects of the tracheal mite. The pathogen
Paenibacillus larvae is the most serious honey bee pathogen and causes American
foulbrood (AFB), which is a disease of larval honey bees. AFB resulted in large
colony losses in the 1940s, but its incidence has been reduced by the use of
antibiotics and increased apiary inspection programs. Nevertheless, mite and
pathogen infestations have likely raised beekeeper operating costs to pay for
miticides and/or antibiotics, labor and expenses for treatment, improved management
and inspection, and colony replacement of dead bees.
Symptoms similar to those observed for CCD have been described in the past,
and heavy losses have been documented. It is still not clear whether the current
colony losses are being caused by the same factors or if new contributing factors are
involved.14 MAAREC also reports that large beekeeper operations may have
experienced higher than normal losses compared with the past few years, and heavy
overwintering losses were reported in 2003-2004 for many northern beekeepers.
How CCD Differs from Past Bee Colony Losses
Ways in which current bee colony losses seem to differ from past losses include
! colony losses are occurring mostly because bees are failing to return
to the hive (which is largely uncharacteristic of bee behavior),
! bee colony losses have been rapid,
! colony losses are occurring in large numbers, and

! the reason why these losses are occurring remains still largely
unknown.
The current phenomenon was first called “Fall-Dwindle Disease,” but has been
renamed CCD because of the unusual characteristics of the honey bee colony
declines. First, the condition is not only seasonal but manifests itself throughout the
year. Second, the term “dwindle” implies a gradual loss; CCD onset is sudden.
Third, the term “disappearance” has been used to describe other types of conditions,
which differ from the symptoms currently being associated with CCD. Finally, the
term “disease” is usually associated with a biological agent but none has yet been
identified.15
The first report of CCD was in mid-November 2006 by a Pennsylvania
beekeeper overwintering in Florida. By February 2007, large commercial migratory
beekeepers in several states reported heavy losses associated with CCD (Figure 1).
Reports of losses vary widely, ranging from losses of 30-90% of their bee colonies;
some beekeepers fear loss of nearly all of their colonies in some cases.16 Surviving
colonies are reportedly weakened and may no longer be viable to pollinate or produce
honey. Losses have been reported in migratory operations wintering in California,
Florida, Oklahoma and Texas. In late February, some larger non-migratory
beekeepers in the mid-Atlantic and Pacific Northeast regions also reported significant
losses of more than 50%.17 Honey bee colony losses also have been reported in
Canada and Europe.
Symptoms of Colony Collapse Disorder
One of the key symptoms of CCD in collapsed colonies is that the adult
population is suddenly gone without any accumulation of dead bees.18 The bees are
not returning to the hive but are leaving behind their brood (young bees), their queen,
and maybe a small cluster of adults. What is uncharacteristic about this situation is
that the honey bee is a very social insect and colony-oriented, with a complex and

organized nesting colony. Failing to return to the hive is considered highly unusual.
An absence of a large number of dead bees makes an analysis of the causes of CCD
difficult. Also there is little evidence that the hive may have been attacked. In
actively collapsing colonies, an insufficient number of adult bees remain to care for
the brood. The remaining workforce seems to be made up of young adult bees. The
queen is present, appears healthy and is usually still laying eggs, but the remaining
cluster is reluctant to consume feed provided by the beekeeper, and foraging is
greatly reduced.

Possible Causes of Colony Collapse Disorder
To date, the potential causes of CCD, as reported by the scientists who are
researching this phenomenon, include but may not be limited to19
! parasites, mites, and disease loads in the bees and brood;
! known/unknown pathogens, such as fungal diseases;
! poor nutrition among adult bees;
! lack of genetic diversity and lineage of bees;

! level of stress in adult bees, as indicated by stress-induced proteins
(e.g., transportation and confinement of bees, or other environmental
or biological stressors);
! chemical residue/contamination in the wax, food stores and/or bees,
including exposure to new types of agricultural pesticides as well as
exposure to chemicals that beekeepers use to control mites; and
! a combination of several factors.
Some practices and conditions have been tentatively removed from the list of
possible causes of CCD. These include feeding practices, chemicals used by
beekeepers (such as antibiotics and miticides), use of bees (primarily for honey
production versus pollination), and queen source.20 However, the scientists who are
researching this phenomenon note these could contribute to the risk of bee colonies
developing CCD.
High levels of bacteria, viruses, and fungi have been found in the guts of the
recoverable dead bees. Some researchers have speculated that these high infection
levels may be compromising the immune system of the honey bees.21 Others have
speculated that because most of the reported colony losses are among large
commercial migratory operations, which may move bees two to five times during a
growing season, the current disorder may be the result of accumulated stress, and
factors such as confinement and temperature fluctuations. These stresses may
increase the colony’s susceptibility to disease and may also increase its potential
exposure to other diseases and parasites.22
Of the possible causes of CCD being examined, one that has become the subject
of debate is whether certain chemicals or combinations of chemicals could be
contributing to CCD, including some pesticides and possibly some fungicides. One
class of insecticide being studied are neonicotinoids, which contain the active
ingredient imidacloprid, and similar other chemicals, such as clothianidin and
thiamethoxam. Honey bees are thought possibly to be affected by such chemicals,
which are known to work their way through the plant up into the flowers and leave
residues in the nectar and pollen. The scientists studying CCD note that the doses
taken up by bees are not lethal, but they are concerned about possible chronic
problems caused by long-term exposure. As noted by the NRC, some studies report
sublethal effects of pesticides on bee foraging behavior that may impair the
navigational and foraging abilities of honey bees.23 Concerns about imidacloprid, as

reported by beekeeping associations in the United Kingdom and France24 and by
some U.S. beekeepers,25 have focused on its potential to affect complex behaviors in
insects, including flight, navigation, olfactory memory, recruitment, foraging, and
coordination. However, the NRC and some scientists who study CCD note there is
conflicting information about the effect of these pesticides on honey bees. Still, the
U.S. Environmental Protection Agency has identified some of these chemicals as
highly toxic to honey bees,26 and use of some of these pesticides has reportedly been
discontinued in parts of Europe because of their potential effects on pollinators.27
Congressional Response
Prior and existing laws have been enacted to support the U.S. beekeeping sector
and to ensure continued pollination for agricultural crops. For example, in 1970,
Congress authorized the Beekeeper Indemnity Program.28 This program was
administered by USDA and partially compensated beekeepers for colony losses due
to exposure to agricultural pesticides that had been approved by the federal
government. Beekeepers who exercised reasonable precautions to avoid pesticide
damage but still lost bees were eligible to apply for indemnity payments after January
1, 1967. This program expired in 1977.
The existing federal Honeybee Act authorizes USDA’s Animal and Plant Health
Inspection Service (APHIS) to regulate the importation of honey bees and related
material to prevent the entry of honey bee diseases and parasites, as well as
undesirable subspecies of honeybees.29 Several states also have apiary inspection
programs to prevent the spread of diseases such as AFB and parasitic mites. Funding
is provided for a range of pollinator and bee disease research programs within
USDA.

On March 29, 2007, the House Subcommittee on Horticulture and Organic
Agriculture is to hold a hearing to review the recent honey bee colony declines
reported throughout the United States. Based on information presented to Congress,
both by scientists researching recent bee colony declines and by agricultural
producers who may be potentially affected by these losses, Congress could consider
options for subsequent action in this area.
