Our bees rely upon us to build their hives. We must plan
ahead and build enough hive bodies to accommodate a large colony and enough
supers to hold next summer’s honey. Effective beekeepers learn when major
nectar flows occur so that they can place the supers on their hives in time to
gather a surplus of honey. When we harvest and extract honey, we are also
preparing the combs for next year’s honey crop. When we treat our hives for Varroa
mites in the fall, we are killing mites at the time and ensuring that we will
have a larger population of bees to maintain a warm cluster in the winter. When
we provide supplemental feedings in the fall, we are encouraging our queens to
extend their egg laying, ensuring that we will have plenty of longer-lived
worker bees to produce the brood food for next year’s first brood. Likewise, when
we set up our hives for winter, we are actually setting the conditions for
finding a healthy colony in the spring.

Looking Ahead
Good beekeepers are always thinking six months in advance.
When we make our first brief hive inspection in late winter, we check to see if
the bees survived the winter. At the same time, we are also checking to see if
the colony has the potential to expand into a strong summer colony. If the bees
didn’t survive the winter, we protect the combs so that we can fill the hive
with a new colony in the spring. When we feed our bees pollen and sugar syrup
in the spring, we stimulate the queen to lay eggs and produce a large
population of bees to gather an abundance of summer honey or pollinate crops.
In the spring, when we reverse our hive bodies and expand the brood nest by
rearranging brood frames, not only are we providing space for our queens to lay
eggs now, we are also reducing the bees’ desire to swarm later on.

A Warm Winter
We are continuously reminded that the climate is in
change. Measurements made by NASA and NOAA revealed that the earth warmed to
record levels this past year
(www.washingtonpost.com/news/energy-environment/wp/2016/01/20/its-official-2015-smashed-2014s-global-temperature-record-it-wasnt-even-close/?wpisrc=nl_rainbow).
Following this warm year, our Mid-South winter has been so mild that it seems
more like an extended fall season. While warm winter weather makes for
comfortable days for humans, it potentially leads to starvation of honey bee
colonies. Normally, in the winter honey bees remain clustered together for
warmth inside their hive and only fly when the outside temperature rises above
50 degrees Fahrenheit. This year’s warm temperatures have been the trend
through this mild winter. Flying bees search for flowers in bloom to forage for
nectar and pollen. Unfortunately, few blooms are available at this time of the
year. Flying expends more energy than the bees would require if they remained
clustered inside their hives. The result is the bees consume their honey stores
faster than in cooler winters. Several area beekeepers have already experienced
losing colonies to starvation, which usually peaks in March in the Mid-South.
It is a good idea for beekeepers to supply some emergency feeding of sugar to
hives that are light in weight at this time.
Today’s photo reveals a colony of bees that died of
starvation. You can see that the queen has been laying eggs by the fact that
the cluster of bees is gathered around capped cells of pupae. The bees must
maintain a 95 degree temperature in the brood area. The bees consume plenty of
honey to generate the heat to warm the brood. The fact that the colony died of
starvation is readily revealed by the dead bees with their heads downward in
the cells. Due to the honey bees’ food-sharing behavior, the entire colony dies
at one time as the honey stores in the hive are depleted. Beekeepers need to
watch their hives carefully for a few more weeks until flowers spring into
bloom.

Pax Vobiscum
I recently completed my tenure presiding over the
Arkansas Beekeepers Association. It was a true honor to be entrusted with the
leadership of the state’s beekeeping trade association. In this role I had
great help. A capable team of committed volunteer leaders from all areas of the
state played an important role in planning and conducting the association’s
tasks. These leaders, the Officers and Regional Directors of the ABA’s
Executive Committee, included James Rhein, Larry Kichler, Britt Bailey, Linda
Rhein, Alan Isom, Howard Waddell, Steve Cline, Patrick Edwards, Jeremy Bemis,
Howard Hawthorn, Richard Coy, Melissa Mencer, and Jon Zawislak. Each of these
individuals assisted in conducting our educational conferences and bee
equipment trade shows and assisted roughly 30 local beekeeping associations
representing 2000 beekeepers.
Recent years have found me increasingly involved in
training and mentoring of beekeepers. I have been conducting beekeeping
training classes with Jeremy Bemis at Bemis Honey Bee Farm in Little Rock,
Arkansas. We are finding great interest in beekeeping training, especially
among the expanding number of new beekeepers. Further, I was honored to be
asked to participate in the development of a new beekeeping college located in
one of the villages where I trained beekeepers in Africa. My host, Wubishet
Adunga, is building the college located at Bonga in the highlands of southwestern
Ethiopia. For this project I edited the curriculum for the Apinec Apiculture
Technical Vocational and Education Training College. Beekeeping and production of
hive products are important for food security in the developing world. The
worldwide communications between beekeepers and the efforts being taken to provide
training and protect bees and the beekeeping industry is visible in today’s
photo. At a meeting of the Eastern Apicultural Society, I noticed a picture of
myself inspecting brood in one of my Arkansas bee yards. The picture is on the
cover of training manuals published in England by Bee Craft. The Underhills of Peace Bee Farm wish beekeepers and
peace-loving people worldwide that peace be with you.

Nature of Conservation
Judith Rutschman interviewed me on a segment of her
TV program, Nature of Conservation.
The recent interview was my second filming of the program. Our first interview
in 2008 discussed Peace Bee Farm’s activities, mostly producing honey and beeswax
products. At that time, a mysterious condition in which the adult worker bees
disappeared from their hives was in its second year. We discussed the researchers’
efforts being undertaken to identify the causes of the resulting massive honey
bee die-off, called Colony Collapse Disorder, or CCD.
With the passing of seven years, Judith and I revisited
Peace Bee Farm’s operations and the condition of honey bees across America and
around the world. The continuing die-off of bees brought about ample media
coverage, resulting in considerable public interest. Media attention helped
bring about a number of university studies seeking the cause of CCD. Peace Bee
Farm participated in several of these studies. Many concerned individuals
responded by purchasing bees and hives. These new beekeepers eagerly sought
beekeeping training and guidance. My role shifted over the next years to more
involvement in beekeeping training and mentoring. After a few years of training
beekeepers in the Mid-South, I was given the opportunity to travel to Africa to
train beekeepers in Ethiopia. In some of my African assignments, I taught
experienced beekeepers how to transition from traditional hives placed high in
tree tops to modern bee hives. Sometimes I trained seasoned African beekeepers
in new skills to share with others when they returned to their local villages.
At other times I gave farmers their first lessons in beekeeping. These men and
women built Kenyan Top Bar Hives at no cost using materials that they gathered
locally: wood scraps, sticks, mud, and cow dung. It was always heartwarming to
know that the products of the bee hives, honey and beeswax, helped increase the
farmers’ incomes and ultimate survivability. Today’s photo: Judith Rutschman
and Richard Underhill. See Nature of
Conservation on WYPL, Memphis Channel 24, in December.

Bee-Lining in the Ozarks
The Arkansas Beekeepers Association hosted Dr. Tom
Seeley of Cornell University at its fall conference in Mountain View, Arkansas.
Dr. Seeley shared his research findings based upon years of observation and
carefully designed experiments that revealed much about the behavior of honey
bee colonies. Much of Dr. Seeley’s research was conducted in Cornell’s Ithaca,
New York Arnot Forest, a 4500 acre old-growth forest with ample mature,
storm-damaged trees providing natural nesting cavities for feral honey bees.
Dr. Seeley employed a technique used by honey hunters of earlier times to locate
bee trees holding active honey bee colonies: bee-lining. Dr. Seeley brought a
bee-lining box, the small wooden, two-compartment box shown in today’s photo.
Between speaking presentations, Dr. Seeley and other interested beekeepers used
the bee-lining box to capture foraging worker bees at the Ozark Folk Center’s
native plant pollinator garden. At the box, foraging worker bees were fed honey
or sugar syrup placed on a small piece of honeycomb. When a bee’s honey crop
was full, she was released from the box to fly. The beekeepers watched the bee
circle, orienting on the sun, and then fly away in a “bee line” to its hive,
likely a hollow tree. Watching the bee silhouetted against the sky provided an
accurate direction to the bee tree.
University of Arkansas Extension Apiary Specialist Jon
Zawislak painted a red dot on the thorax of a forager as she engorged on honey
at the bee-line box. She flew away, and then she returned eight minutes later.
Timing the bee’s two-way flight plus the time involved in her dancing and
passing off her gathered honey provides an insight into the distance to the bee
tree. Employing bee-lining, Dr. Seeley determined that honey bees choose
natural hives that are at least 10 feet above the ground, highly visible, well
shaded, and with an entrance facing south. Dr. Seeley, by the way, has a bee
species named after him: Neocorynurella
seeleyi. How cool is that!

Feral Bees and Swarms
Speaking at the Arkansas Beekeepers Association’s
fall conference in Mountain View, Arkansas, Dr. Tom Seeley, author of Honeybee Democracy, described his
genetics study of feral honeybees collected at Cornell University’s Arnot
Forest in 1977 and 2010, http://www.nature.com/ncomms/2015/150806/ncomms8991/full/ncomms8991.html.
The study analyzed honey bees before and after the arrival of parasitic Varroa
mites. Surprisingly, colony densities in the forest remained the same after the
introduction of the mites. Bees collected in 2010 were, however, the offspring
of only a few surviving colonies that repopulated the forest. Finding feral survivor
colonies is encouraging news for beekeepers.
Other work by Dr. Seeley defined the mechanisms
honeybees employ in swarming. To determine honey bees’ preferences for choosing
a nesting site Dr. Seeley used numerous swarm catcher hives. He questioned: How
large a cavity? How large an entrance hole? Hive in the sun or shade? Direction
hive should face? Can the hive be drafty? Can the hive be damp? Answering these
questions help us design effective swarm catcher hives. Bees choose hives according
to their ability to correct hive deficiencies. For example, if a hive is
drafty, bees will often accept it because they can easily fill drafty cracks
with propolis. On the other hand, bees will often reject a hive in the full sun
because it is more difficult to cool in the summer. Pixar Studios filmed honey
bee swarms moving from their swarm resting site to their permanent hive. Observing
individual bees in flight lead to an understanding of how workers guide the
swarm. Of great interest was Dr. Seeley’s finding of feral honey bee colonies
surviving in the forest while carrying parasitic Varroa mites. Two significant
factors seem to support the feral colonies’ survival. First, there is little
drifting of forest bees. Next, honey bees in nature prefer a nest cavity of
approximately 40 liters, close to that of a single Langstroth hive body. Small
cavity hives develop brood nest congestion, leading to swarming. Swarming interrupts
Varroa mite reproduction. Today’s photo: Ozark Mountain maples.

Savannah, Tennessee
I spent a few most interesting fall days at
Savannah, Tennessee with friends who, like me, devote much time studying
history and honey bees. We combined our interests while visiting historic areas
in the Tennessee River Valley. Jerry Hayes, Shirley Murphy, and I walked the fields
and woods of Shiloh National Military Park, http://www.nps.gov/shil/learn/historyculture/shiloh-history.htm,
the site of the horrific 1862 Civil War battle. Here, on the battlefield
grounds we retraced the steps of ancestors who fought on both sides of the
conflict. Shown in today’s photo are some of the 62 Confederate artillery
pieces concentrated in Duncan Field, bearing down on the Sunken Road and Hornet’s
Nest. We also visited other historic sites in the surrounding area, including
the city of Savannah, where General U. S. Grant maintained his headquarters at
the Cherry Mansion. Close by on Savannah’s Main Street the Tennessee River
Museum, http://www.tennesseerivermuseum.org/exhibits.html,
offers detailed views of the area’s Native American Mississipian culture, the
U. S. Army’s forced removal of the Cherokee Nation in a march through Savannah
known as the Trail of Tears. The museum also depicts pioneer life in the
Tennessee River Valley.
Jerry and I visited Shirley’s well-tended bee hives
before Jerry’s presentation at a meeting of the Savannah Area Beekeepers
Association. Jerry, who has made a career of honey bee health issues, discussed
current research into controlling Varroa mites and the viruses that they vector.
He explained that some basic research that Monsanto is conducting with RNA interference
technology, RNAi, offers promise. Jerry writes the popular “Classroom” section
of the American Bee Journal. He conducted a live version of The Classroom for
the Arkansas Beekeepers Association. Shirley is the charter president of the
Savannah Area Beekeepers Association, an active group of Tennessee River Valley
beekeepers. Shirley and I worked together, sharing our best honey bee genetic stock
to breed locally adapted queens. Honey bee health improvement involves the
efforts of devoted beekeepers in bee yards and researchers in labs. History
surrounds us.
