AY Honors/Beekeeping/Answer Key

1. Know a brief history of keeping bees for honey.

Beekeeping is one of the oldest forms of food production. It was particularly well developed in Egypt and was discussed by the Roman writers Virgil, Gaius Julius Hyginus, Varro, and Columella. A pioneering beekeeping popularizer in the 19th century United States was Amos Root.

Traditionally, beekeeping was done for the bees' honey harvest, although nowadays crop pollination service can often provide a greater part of a commercial beekeeper's income.

Western honeybees are not native to the Americas. American, Australian, and New Zealand colonists imported honeybees from Europe, partly for honey and partly for their usefulness as pollinators. The first honeybee species imported were likely European dark bees. Later Italian bees, carniolan honeybees and caucasian bees were added.

2. List at least five uses of each of the following:

a. Honey

The main uses of honey are in cooking, baking, spreading on bread or toast, and as an addition to various beverages such as tea. Because honey is hygroscopic (drawing moisture from the air), a small quantity of honey added to a pastry recipe will retard staling. Raw honey also contains enzymes that help in its digestion, several vitamins and antioxidants.

Honey is used in traditional folk medicine and apitherapy, and is an excellent natural preservative.

In ancient history, the Ancient Egyptian and Middle-Eastern peoples also used honey for embalming the dead. However, only rich and powerful people had the luxury of this type of funeral.

b. Beeswax

Beeswax is used commercially to make fine candles, cosmetics and pharmaceuticals including bone wax (cosmetics and pharmaceuticals account for 60% of total consumption), in polishing materials (particularly shoe polish), as a component of modelling waxes, and in a variety of other products. It is also used as a coating for cheese, to protect the food as it ages. While some cheesemakers have replaced it with plastic, many still use beeswax in order to avoid any unpleasant flavours that may result from plastic. Beeswax is also an ingredient in moustache wax, as well as dreadlock wax, and was used in the manufacturing of the cylinders used by the earliest phonographs.

c. Propolis

Propolis is a wax-like resinous substance collected by honeybees from tree buds or other botanical sources and used as cement and to seal cracks or open spaces in the hive. Propolis is marketed by health food stores as a traditional medicine, and for its claimed beneficial effect on human health. Depending upon its precise composition it may show powerful local antibiotic and antifungal properties. Also it is generally efficient in treating skin burns. Claims have been made for its use in treating allergy; it may stimulate the immune system, but some warn that it should not be taken if the user is likely to have severe allergic reaction to bees.

Old beekeepers recommend a piece of propolis kept in the mouth as a remedy for a sore throat.

Propolis is used by music instrument makers to better show the wood grain. It is a component of Italian varnish and was reportedly used by Stradivari

3. Name ten foods that would be very difficult to grow if there were no honey bees.

• Almonds
• Apples
• Blackberries
• Blueberries
• Cantaloupe
• Cucumber
• Kiwi
• Peach
• Pumpkin
• Raspberry
• Squash
• Strawberries
• Watermelon

4. List the duties of the drone, the worker, and the queen bees.

Drones

Drones are male bees, and their only function is to mate with the queen. A healthy hive will have a few thousand drones (out of a population of 40,000 to 80,000 bees). Drones do no work in the hive and will beg food from the worker bees. If none supply him with food, he will eventually feed himself. The phrase "busy as a bee" certainly does not pertain to the drone! Once mature, drones leave the hive and congregate together, waiting for a queen with which to mate. Only one drone will mate with the queen, and shortly after that it will die. The worker bees do not allow the drones to overwinter in the hive, as they are a tremendous drain on resources and serve no function during the winter when the queen lays no eggs. They are sometimes ejected from the hive when food is scarce. Drones are hatched from unfertilzed eggs, so the lack of any drones in the hive will automatically result in the production of drones when the next brood is hatched.

Workers

Workers are sexually sterile female bees. Most bees are worker bees. For the first ten days of their lives, the female worker bees clean the hive and feed the larvae. After this, they begin building comb cells. On days 16 through 20, a worker receives nectar and pollen from older workers and stores it. After the 20th day, a worker leaves the hive and spends the remainder of its life as a forager. The foragers die usually when their wings are worn out after approximately 500 miles of flight.

Queen

The queen bee is the only female bee that lays eggs. The queen's eggs hatch in three days, and the larvae are fed with royal jelly produced by worker bees. After a few more days, the larvae are fed on honey and pollen. The exception is a larva fed solely on royal jelly, which will develop into a queen bee. When the queen dies, the worker bees produce several new queens, and when these mature, they fight to the death until only one queen is left.

6. What is meant by the following terms:

a. Movable-frame hive

b. Crossed comb

c. Bee space

d. Swarming

Swarming is the natural means of reproduction of honeybee colonies (considering the colony as the organism rather than individual bees which cannot survive alone). In the process two or more colonies are created in place of the original single colony. It is considered good practice in beekeeping to reduce swarming as much as possible by several techniques, as allowing this form of reproduction often results in the loss of the more vigorous division, and the remaining colony being so depleted that it is unproductive for the season.

7. What is a smoker? What materials make good fuel for a smoker?

A well-used bee smoker

Smoke is the beekeeper's second line of defense; protective clothing provides remarkably little protection from agitated bees. Most beekeepers use a "smoker"—a device designed to generate smoke from the incomplete combustion of various fuels. Smoke calms bees; it initiates a feeding response in anticipation of possible hive abandonment due to fire. Smoke also masks alarm pheromones released by guard bees or when bees are squashed in an inspection. The ensuing confusion creates an opportunity for the beekeeper to open the hive and work without triggering a defensive reaction. In addition, when a bee consumes honey the bee's abdomen distends, making it difficult to make the necessary flexes to sting.

Smoke is of no use with a swarm, because swarms do not have honey stores to feed on in response. Usually smoke is not needed since swarms tend to be less defensive, as they have no stores to defend, and a fresh swarm will have fed well from the hive.

Many types of fuel can be used in a smoker as long as it is natural and not contaminated with harmful substances. These fuels include hessian, cardboard, and rotten or punky wood. Some beekeeping supply sources also sell commercial fuels like pulped paper and compressed cotton, or even aerosol cans of smoke.

Proper smoker fuels

• burlap rags, cotton rags, cotton string or twine
• Woodchips, pine needles, twigs, sticks, dried leaves and grass
• Stove pellets
• Charcoal (burns long and hot, may be best to use with other fuel)
• Tobacco

Improper smoker fuels

• poison ivy, poison sumac, etc
• insulation material
• plastic or rubber
• newspaper (as sole fuel source)
• greasy rags

9. How are honey bee diseases spread from hive to hive?

There are two main ways disieases are spread from one hive to another: by the bees, and by the beekeeper. Spreading by bees is covered in the next requirement.

The beekeeper must keep his tools clean. If disease is detected in one of the hives, the beekeeper must take steps to control the disease, and must thoroughly clean the beekeeping tools between hives. Failure to do this will cause the pathogen to spread to the remaining hives.

Beekeepers spread disease by moving infected frames from one hive to another, by not cleaning out dead hives (encouraging robbing), using old, infected equipment, and by not recognizing the presense of disease (and thus not treating it). Inattentive beekeepers are responsible for most bee disease among their hives.

10. What is robbing? Describe a robber bee.

Robbing among bees is about the same thing that it is among people. A bee that invades another hive is a robber bee. If the hive is unable to defend against the robber, the robber will gather as much honey as it can carry and take it back to its own hive. This is done during times of low nectar availability (it's a lot less risky for a bee to gather nectar than it is for her to invade another hive).

If the robber's hive is infected, she may carry the disease to the invaded hive. If the invaded hive is infected (more likely), she may carry disease back to her own hive.

11. Name four ways to help prevent swarming. Why should swarming be prevented?

During the first year of a queen's life the colony has little incentive to swarm, unless the hive is very crowded. During her second spring, however, she seems to be programmed to swarm. Without beekeeper "swarm management" in the second year, the hive will cast a "prime swarm" and one to five "after swarms." The old queen will go with the prime swarm, and other swarms will be accompanied by virgin queens.

Swarming is to the beekeeper what losing all of his calves is to a cattleman. The hive that cast the swarm is often so badly depleted that it will be unproductive for the entire season. For this reason, beekeepers try to anticipate swarming and assist the bees to reproduce in a more controlled fashion by splitting hives. This saves the "calves" and keeps the "cow" in condition to accomplish some work.

Beekeepers that do not wish to make increase may use one or more of the many methods for swarm control. Most methods simulate swarming to extinguish the swarming drive.

The Demaree method of swarm control is to remove a frame of capped brood with the queen. This frame is put in a hive box with empty drawn frames and foundation at the same location of the old hive. A honey super is added to the top of this hive topped by a crown board. The remaining hive box is inspected for queen cells. All queen cells are destroyed. This hive box, which has most of the bees, is put on top of the crown board. Foraging bees will return to the lower box depleting the population of the upper box. After a week to ten days both parts are inspected again and any subsequent queen cells destroyed. After another period of separation the swarming drive is extinguished and the hives can be re-combined.

Another common swarming control method is to simply keep the brood nest open. In preparation for swarming bees fill the brood nest with honey which causes the queen to stop laying which slims her down to fly and leaves nurse bees unemployed to go with her. The concept of this method is to open the brood nest to employ those nurse bees and get the queen laying again and redirect this sequence of events. This is done by any number of slight variations from empty frames in the brood nest, frames of bare foundation in the brood nest or drawn combs in the brood nest, or moving brood combs to the box above to cause more expansion of the brood nest.

Another swarming control method is called checkerboarding. In the early spring, frames are rearranged above the growing brood nest. The frames above the brood nest are alternated between full honey frames and empty drawn out frames or even foundationless frames. It is believed that only colonies that have enough reserves will attempt to swarm. Checkerboarding frames above the brood nest apparently destroys this sense of having reserves.
