Bee smoker

A bee smoker (usually called simply a smoker or a smokepot) is a device used in beekeeping to calm honey bees. It is designed to generate smoke from the smouldering of various fuels, hence the name.

History

Moses Quinby

Long before the invention of the bee smoker, humans had discovered that smoke calmed bees. It is not clear when this practice started but it has been used in various parts of the world where honey is collected in the wild. A camp fire can be started in near proximity to the nest, then a smouldering stick or torch can be brought to the nest to diffuse smoke in the honeybees general vicinity. This technique is still used today in Nepal to collect wild psychotropic honey from cliff colonies.[1]

Moses Quinby invented the modern bee smoker with a bellow attached to a tin burner in 1873 in the Mohawk Valley, New York. When combined with a wooden dowel with a handle on one end and the smoking end of a long thin rod on the other end, a short wooden stick on the end of the stick is used to blow air into the metal bowl. As part of his Quaker upbringing and belief, he did not patent any of his inventions (including the smoker) and therefore gave it to the beekeeping community.[2][3] Tracy F. Bingham of Farwell, Michigan improved and patented on January 20, 1903 (US Patent # US718689A) an improved smoker based on the design of Quinby.[4]

There are many modifications to the basic original design. Since the burner can get very hot, a safety guard against burns is often placed into the second, outer can (making the smoker double wall). Alternatively, the burner can be surrounded with a protective wire cage.

Action and usage

The fact that smoke calms bees has been known since ancient times; however, the scientific explanation was unknown until the 20th century and is still not fully understood. Smoke masks alarm pheromones[5] which include various chemicals, e.g., isopentyl acetate[6] that are released by guard bees or bees that are injured during a beekeeper's inspection. The smoke creates an opportunity for the beekeeper to open the beehive and work while the colony's defensive response is interrupted. In addition, smoke initiates a feeding response in anticipation of possible hive abandonment due to fire.[7][8][9]

Smoke is of limited use with a swarm, partly because swarms have no honey stores to feed on. It is usually not needed, either, since swarms tend to be less defensive as they have no home to defend, and a fresh swarm will have fed well at the hive it left behind.

Design and operation of a traditional smoker

Many types of fuel can be used in a smoker.[10] These fuels include Hessian fabric (burlap), pine needles, corrugated cardboard, paper egg cartons, and rotten wood or herbs.[11] Some beekeeping supply sources also sell commercial fuels like pulped paper and compressed cotton. Experiments have shown that smoke from pellets of the dried female hop flower (Humulus lupulus), containing the sedative lupulin, is particularly effective.[12]

The fuel in the smoker's burner smoulders slowly due to the restriction of oxygen in the burning chamber. When needed, a squeeze of the bellows provides a blast of fresh air which feeds the smouldering fuel and produces smoke. In this way the fuel is used more sparingly than in an open pan and one load of fuel may last for several hours or even days if it is extinguished and rekindled again later. To effectively calm the bees, the smoke must not be too hot.
