Checkerboarding is a term used in beekeeping that describes a specific hive management technique to prevent swarming. The technique was developed by Walt Wright, a long time beekeeper from Tennessee.[1][2]
Checkerboarding takes advantage of the bee colony's primary motivation, which is survival as survival of the existing colony takes priority over swarm preparation and swarming. Bees will not prepare for a reproductive swarm if they perceive the survival of the existing colony might be jeopardized. It is hypothesized that swarm preparation starts in the late winter. The over-wintering colony consumes honey and expands the brood volume. At this point, the bee colony apparently senses that it has enough remaining honey stores and a large enough brood nest to risk swarm preparation. The bee colony's first activity of swarm preparation is to reduce the brood volume by creating additional stores inside the brood area. As brood emerges, selected cells are back-filled with honey, nectar, or pollen. Later into the season, as space for egg laying decreases the queen will not be able to lay as many eggs. This forces the queen to diet and lose weight so she becomes fit for the swarm flight.
Apparently, at the first time this type of backfilling behavior starts is the best time to do the Checkerboarding intervention. It requires filling two hive boxes above the broodnest each alternately with capped honey-filled frames and empty drawn frames. Alternating empty drawn combs above the brood nest "fools" the bees into thinking they don't have enough stores yet for swarming and causes them to expand the brood nest, giving both a bigger field force and avoiding reproductive swarming.
Timing the checkerboarding intervention is very important (note that all these times are different reference points that refer to the same time in the United States). The best time for the intervention is:
A honey bee is a eusocial flying insect within the genus Apis of the bee clade, all native to Eurasia. They are known for their construction of perennial colonial nests from wax, the large size of their colonies, and surplus production and storage of honey, distinguishing their hives as a prized foraging target of many animals, including honey badgers, bears and human hunter-gatherers. Only eight surviving species of honey bee are recognized, with a total of 43 subspecies, though historically 7 to 11 species are recognized. Honey bees represent only a small fraction of the roughly 20,000 known species of bees.
A beehive is an enclosed structure in which some honey bee species of the subgenus Apis live and raise their young. Though the word beehive is commonly used to describe the nest of any bee colony, scientific and professional literature distinguishes nest from hive. Nest is used to discuss colonies that house themselves in natural or artificial cavities or are hanging and exposed. Hive is used to describe an artificial/man-made structure to house a honey bee nest. Several species of Apis live in colonies, but for honey production the western honey bee and the eastern honey bee are the main species kept in hives.
Beekeeping is the maintenance of bee colonies, commonly in man-made hives, by humans. Most such bees are honey bees in the genus Apis, but other honey-producing bees such as Melipona stingless bees are also kept. A beekeeper keeps bees in order to collect their honey and other products that the hive produce, to pollinate crops, or to produce bees for sale to other beekeepers. A location where bees are kept is called an apiary or "bee yard".
In beekeeping, bee brood or brood refers to the eggs, larvae and pupae of honeybees. The brood of Western honey bees develops within a bee hive. In man-made, removable frame hives, such as Langstroth hives, each frame which is mainly occupied by brood is called a brood frame. Brood frames usually have some pollen and nectar or honey in the upper corners of the frame. The rest of the brood frame cells may be empty or occupied by brood in various developmental stages. During the brood raising season, the bees may reuse the cells from which brood has emerged for additional brood or convert it to honey or pollen storage. Bees show remarkable flexibility in adapting cells to a use best suited for the hive's survival.
The term queen bee is typically used to refer to an adult, mated female (gyne) that lives in a honey bee colony or hive; a female bee with fully developed reproductive organs, she is usually the mother of most, if not all, of the bees in the beehive. Queens are developed from larvae selected by worker bees and specially fed in order to become sexually mature. There is normally only one adult, mated queen in a hive, in which case the bees will usually follow and fiercely protect her.
A top-bar hive is a single-story frameless beehive in which the comb hangs from removable bars. The bars form a continuous roof over the comb, whereas the frames in most current hives allow space for bees to move up or down between boxes. Hives that have frames or that use honey chambers in summer but which use similar management principles as regular top-bar hives are sometimes also referred to as top-bar hives. Top-bar hives are rectangular in shape and are typically more than twice as wide as multi-story framed hives commonly found in English speaking countries. Top-bar hives usually include one box only, and allow for beekeeping methods that interfere very little with the colony. While conventional advice often recommends inspecting each colony each week during the warmer months, heavy work when full supers have to be lifted, some beekeepers fully inspect top-bar hives only once a year, and only one comb needs to be lifted at a time.
A worker bee is any female (eusocial) bee that lacks the full reproductive capacity of the colony's queen bee; under most circumstances, this is correlated to an increase in certain non-reproductive activities relative to a queen. While worker bees occur in all eusocial bee species, the term is rarely used for any bees other than honey bees.
A drone is a male honey bee. Unlike the female worker bee, drones do not have stingers. They gather neither nectar nor pollen and are unable to feed without assistance from worker bees. A drone's only role is to mate with an unfertilized queen.
Swarming is a honey bee colony's natural means of reproduction. In the process of swarming, a single colony splits into two or more distinct colonies.
Hive management in beekeeping refers to intervention techniques that a beekeeper may perform to ensure hive survival and to maximize hive production. Hive management techniques vary widely depending on the objectives.
Nucs, or nucleus colonies, are small honey bee colonies created from larger colonies. A nuc hive is centered on a queen bee, the nucleus of the honey bee colony.
Stingless bees, sometimes called stingless honey bees or simply meliponines, are a large group of bees, comprising the tribe Meliponini. They belong in the family Apidae, and are closely related to common honey bees, carpenter bees, orchid bees, and bumblebees. Meliponines have stingers, but they are highly reduced and cannot be used for defense, though these bees exhibit other defensive behaviors and mechanisms. Meliponines are not the only type of "stingless" bee; all male bees and many female bees of several other families, such as Andrenidae, also cannot sting. Some stingless bees have painful and powerful bites.
In beekeeping, the Demaree method is a swarming prevention method. It was first published by George Demaree (1832–1915) in an article in the American Bee Journal in 1892. Demaree also described a swarm prevention method in 1884, but that was a two-hive system that is unrelated to modern "demareeing".
Apis dorsata, the giant honey bee, is a honey bee of South and Southeast Asia, found mainly in forested areas such as the Terai of Nepal. They are typically around 17–20 mm (0.7–0.8 in) long. Nests are mainly built in exposed places far off the ground, like on tree limbs, under cliff overhangs, and sometimes on buildings. These social bees are known for their aggressive defense strategies and vicious behavior when disturbed. Though not domesticating it, indigenous peoples have traditionally used this species as a source of honey and beeswax, a practice known as honey hunting.
The East African lowland honey bee is a subspecies of the western honey bee. It is native to central, southern and eastern Africa, though at the southern extreme it is replaced by the Cape honey bee. This subspecies has been determined to constitute one part of the ancestry of the Africanized bees spreading through America.
The western honey bee or European honey bee is the most common of the 7–12 species of honey bees worldwide. The genus name Apis is Latin for "bee", and mellifera is the Latin for "honey-bearing", referring to the species' production of honey.
Apis cerana, the eastern honey bee, Asiatic honey bee or Asian honey bee, is a species of honey bee native to southern, southeastern, and eastern Asia. This species is the sister species of Apis koschevnikovi and both are in the same subgenus as the western (European) honey bee, Apis mellifera. A. cerana is known to live sympatrically along with Apis koschevnikovi within the same geographic location. Apis cerana colonies are known for building nests consisting of multiple combs in cavities containing a small entrance, presumably for defense against invasion by individuals of another nest. The diet of this honey bee species consists mostly of pollen and nectar, or honey. Moreover, Apis cerana is known for its highly social behavior, reflective of its classification as a type of honey bee.
Tetragonula carbonaria is a stingless bee, endemic to the north-east coast of Australia. Its common name is sugarbag bee. They are also occasionally referred to as bush bees. The bee is known to pollinate orchid species, such as Dendrobium lichenastrum, D. toressae, and D. speciosum. It has been identified as an insect that collects pollen from the cycad Cycas media. They are also known for their small body size, reduced wing venation, and highly developed social structure comparable to honey bees.
Bombus fervidus, the golden northern bumble bee or yellow bumblebee, is a species of bumblebee native to North America. It has a yellow-colored abdomen and thorax. Its range includes the North American continent, excluding much of the southern United States, Alaska, and the northern parts of Canada. It is common in cities and farmland, with populations concentrated in the Northeastern part of the United States. It is similar in color and range to the American bumblebee and black and gold bumblebee. It has complex behavioral traits, which includes a coordinated nest defense to ward off predators. B. fervidus is an important pollinator, so recent population decline is a particular concern.
Tetragonisca angustula is a small eusocial stingless bee found in México, Central and South America. It is known by a variety of names in different regions. A subspecies, Tetragonisca angustula fiebrigi, occupies different areas in South America and has a slightly different coloration.
