Harvesting Honey at Heifer Ranch

Local beekeeping associations are a community of friends who share a common interest These associations also provide training and experience in the art and science of beekeeping. The Ozark Foothills Beekeepers Association is conducting training in practical beekeeping techniques. Following their beginning beekeeping classes, demonstrations at the bee yard of one of the group’s sponsors, A Bee’s Closet, and presentations at the association’s regular meetings, the association conducted a hands-on training session on harvesting and handling honey at the honey house and bee yard of Heifer Ranch in Perryville, Arkansas. One of the Ozark Foothills’ experienced beekeepers, demonstrated methods of handling and marketing honey.

Everyone got a chance to actually handle the honey. Starting with frames of honey that had been previously taken from the hives, beekeepers removed the beeswax cappings to expose the honey using cold serrated knives. Next, frames were spun in extractors to remove the honey. The group got to use both tangential and radial extractors. The honey poured from the extractors through strainers to remove solid impurities, such as chips of beeswax from the cappings. Beekeepers used a refractometer to measure the moisture content of the honey. Beeswax cappings were left in the uncapping tanks to drain, recovering additional honey. The group bottled and labeled honey held in the bottling unit at 100 degrees Fahrenheit for easy pouring. The raw, unfiltered honey had been maintained at hive temperatures below 120 degrees.

After passing through strainers, honey is allowed to settle in stainless steel or food-grade plastic containers. Since honey is heavy, bubbles or any remaining hive debris floats to the top of the honey where they may be skimmed off and discarded. After frames are spun in the extractors, some honey remains on the combs, and these “wet” frames may be returned to the hives for the bees to refill with honey. After the last honey harvest of the season, supers of “wet” frames are stacked outside for the bees to lick the combs clean for winter storage.

Spiderwort in Bloom

Spiderwort, seen in today’s photo, is in bloom now. This perennial native wildflower is a reliable source of pollen for honey bees. The plant blooms in the morning, with blooms usually closing by noon. Foraging bees learn this bloom period pattern and forage early in the day, collecting ample amounts of pollen, which they deposit in cells close to the brood. Pollen grains, a flowering plant’s male reproductive cells, are found on the anthers of flowers, which in spiderwort stand on stalks in the flower. When a honey bee visits a flower, pollen grains attach to the honey bee’s hairy body, and the bee then grooms the pollen into pollen baskets on her hind legs. Some pollen is inadvertently brushed off the bee onto the sticky stigma of the flower, part of its female reproductive system, pollinating the plant. This accidental pollination by the bee is the first stage in the reproduction of the plant, producing seed and fruit.

Honey bee colonies must forage ample amounts of pollen to support their brood, their developing offspring, which the colony’s nurse bees feed in the larval stage of development. Pollen contains protein, fats, vitamins, and minerals. When pollen is added to honey, a carbohydrate, honey bees have a complete diet, entirely derived from flowers. The pollen, mixed with honey and yeast and bacteria from the bee’s gut microbiome is known as “bee bread.” The yeast starts fermentation of the bee bread that serves as preservation. The fermentation also cracks the hard shell of pollen grains releasing the nutrients. Nurse bees consume the bee bread and produce brood food in glands in their bodies. Brood food is fed to the developing brood in its larval stage.

Springtime Expansion

Honey bee populations expand rapidly in the spring. Prolific queens are stimulated to lay eggs at their maximum rate in April as flowers come into bloom in abundance. Hives fill with bees, and those colonies that do not have enough capacity make preparations for swarming. The same conditions that lead colonies to reproduce by division and swarming are the conditions that queen producers set up when rearing queens, and these newly produced queens are used to establish new colonies. Beekeepers regularly purchase colonies to expand their apiaries or to replace overwinter colony losses. They may purchase entire hives with their established bees, but more frequently they purchase nucleus colonies, “nucs,” or packaged bees like those awaiting delivery at the recent Bee Day event at Bemis Honey Bee Farm shown in today’s photo. Hundreds of previously ordered packages of bees and nucleus colonies were passed out to beekeepers from across the region.

Nucleus colonies are small honey bee colonies derived by separating frames from existing full-size hives. A nuc is a colony in equilibrium. It typically contains five frames of bees on combs with an egg-laying queen, brood, and bees. Since a nuc is an established colony with a queen and combs available for her to continue laying eggs, it is ready to expand in its new hive. A package of bees, on the other hand, is not an established colony when the beekeeper receives it. Typically, it is three pounds of bees measured by weight (approximately 12,000 bees). The bees in the package are not on frames. Included in the package is a queen bee in a cage with the queen separated from the rest of the bees for her protection. She is held in a cage with a candy plug delaying her release into her new hive. Over a few days, workers pass food to the queen and get accustomed to her pheromones while chewing through the candy, releasing her. Then, the bees are a family—a colony.

A Winter Hive Loss

While honey bees do not fly in cold weather, they do venture out of their hive on the occasional warm winter day. Bees make cleansing flights and forage for nectar and pollen from early-blooming flowers. Observing the bees’ flight at the hive entrances, one hive showed less flight activity than adjacent hives. The warm day allowed for an inspection of the evidently weaker hive, revealing a small population of bees with brood present. However, all of the brood was drone brood, no worker brood. Drones are produced from infertile eggs, and workers are produced from fertile eggs. And colonies typically don’t produce drones in the winter. It appeared that some of the workers had developed working reproductive systems and had become drone layers. Workers typically don’t lay eggs, however when a hive has been queenless for a period of time, some workers start laying infertile eggs. It appeared that the colony was dwindling in population without a queen producing workers.

Looking deeper into the hive, I found the likely cause of the colony’s population decline and drone laying. I found a queen cell with the side wall chewed out. It appears that the colony attempted to replace its queen during the winter through supersedure. Honey bees in the Mid-South can only produce viable queens from April through August. The queen cell shown here has not been opened at the tip where a queen would emerge. Instead, it was chewed out through the side. A virgin queen emerged in the hive, found this developing queen, and stung her to death through the side of the cell. Workers later chewed through the cell wall and removed the remains. Beekeepers need to be on the lookout for wintertime colony losses and take measures to protect the combs. I stacked the frames of this hive atop the frames of a strong hive. Those bees will protect the combs, and a colony division in the spring, when queens become available, will restore the hive count.

Mid-Winter Beekeeping

We cannot go deep into our bee hives in the winter, but it is good advice to make a brief inspection of our hives on warm winter days. Breaking hive boxes apart and removing brood frames in cold temperatures risks chilling and killing brood. On warmer days, we can open the hive covers and quickly look inside, simply looking for evidence that the bee colonies are alive and that they have adequate food to survive the remainder of the winter. We may see live bees in a hive as soon as we remove the covers, however the bees may be clustered lower in the hive and not immediately visible. In this case, we can usually determine that we have living bees by removing a frame from the center of the uppermost box to view below. If the colony is dead, we should protect the precious comb-covered frames by stacking them above the frames of a strong hive or placing them in a freezer. We can estimate the amount of stored honey in a hive by lifting the back of our hives an inch with our fingers. Any hives that feel light in weight are likely lacking in stored honey and in need of emergency feeding. As bees are reluctant to consume liquid sugar syrup in cold weather, we may feed bees dry sugar atop the inner covers of the hives. A shim placed between the inner and outer covers allows us to place plenty of sugar on the inner cover.

While existing beekeepers are checking on their overwintering hives, they are also sharing their experience with individuals preparing to start beekeeping. Local beekeeping associations are offering short courses to introduce people to the art and skill of beekeeping. The Ozark Foothills Beekeepers Association held two sessions of its Beekeeping 101 class, and is preparing for a Beekeeping 201 class to be followed in the summer by a class on harvesting and processing honey. An exceptionally large honey bee visited the class.

Pax Vobiscum

 

Heifer Ranch is a working ranch and agricultural demonstration farm at Perryville, Arkansas. This year I witnessed at the ranch how honey bees play a role in restoring and enhancing the environment for both plants and animals. Managed honey bees along with feral colonies and native bees and pollinators play a quiet and barely seen role in the life of the ranch. For instance, bees pollinate legumes, including clover, vetch, lespedeza, alfalfa, partridge peas, and beggar’s lice, as they gather nectar and pollen to feed their colony. Pollination is the first step in the production of seed for these plants growing in pastures. Legumes provide high-value, nitrogen-rich food for livestock and wildlife animals, and legumes are but one family of flowering plants and grasses that feed livestock on the ranch. The livestock, selectively bred to thrive on grasses rather than grain feeds, are managed for sale for human consumption.

As well as producing seed by pollinating plants, bees benefit the environment by enriching the soil. Bacteria dwelling on the roots of legumes convert atmospheric nitrogen into a form suitable for use by plants. Thus, they enrich the soil and promote the growth of pasture grasses and increase the carrying capacity of the land. Regenerative agricultural practices employ measures replicating the natural grazing of wildlife that allows grasses to develop deep roots. Heifer Ranch cattle and sheep, shown here rotating to another of the ranch’s pastures of tall grasses, graze the way bison move across the Great Plains, constantly moving to forage available grasses. The cattle and sheep eat the top growth of the grasses and deposit manure that fertilizes the pastures. Their hooves push nutrients into the soil; the soil improves; grasses develop deeper roots; and the soil retains more water than soil under shallow roots. The honey bee queen ends her short winter break and starts laying eggs on the winter solstice to regenerate the colony. The Underhill family of Peace Bee Farm offer to all: Peace be with you.

Bees Need Water

 

Honey bee foragers collect four things to bring into their hives: nectar, pollen, propolis and water. The bee colony is quite adept at controlling the temperature of its hive. Whenever there is brood in the hive, the bees regulate the temperature in the brood area to 95 degrees. With afternoon temperature climbing above 100 degrees in the shade, it is a challenge for bees to cool their hive, especially if it is located in the full sun. To assist in cooling the hive, foragers bring large amounts of water into the hive, and workers fan their wings over droplets of water. It is important that beekeepers supply their bees with a reliable source of water throughout the year. If there is a natural water source, such as a lake or stream within one quarter of a mile, bees will forage from it. In all other cases, beekeepers need to supply water in containers like we see in today’s photo. Useful water containers are typically placed in sunny locations, and they need floats or rocks for the bees to climb upon while foraging. Supplying water for hives in urban and suburban locations is particularly important, else bees will seek neighbors’ swimming pools. Bees love swimming pool water flavored with chlorine and suntan lotion. Foraging water with a flavor is part of the honey bee’s behavior of sharing the taste of food being foraged. When scout bees discover a food or water source, they share its taste with foragers they are recruiting. The scouts also mark the location of the water source with Nasanov gland pheromone.

On hot afternoons and evenings, bees move outside the hive and rest on the hive’s surface or hang in a bearding fashion to assist in cooling the brood area. Beekeepers can assist their colonies in cooling their hives by painting the hives in light colors. Placing hives to the east side of trees that provide afternoon shade helps cool the bees and the beekeepers working the hives.
