Queen Excluder
In beekeeping, a queen excluder is a selective barrier inside the beehive that allows worker bees but not the larger queens and drones to traverse the barrier. Queen excluders are also used with some queen breeding methods. Some beekeepers believe that excluders lead to less efficient hives as often worker bees, not used to travelling through the excluder, are intimidated and stay in the lower brood box. This can lead to rapid filling of the brood box and overcrowding resulting eventually in the hive swarming. Purpose The intent of the queen excluder is to limit the queen's access to the honey supers. If the queen lays eggs in the honey supers and a brood develops in them it is difficult to harvest clean honey. It makes fall management more difficult. Queen excluders are removed in the autumn; otherwise, the queen would not be able to move with the winter cluster and would die from exposure. A replacement queen can be difficult to introduce because the bees will not be ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Langstroth Hive
In modern American beekeeping, a Langstroth hive is any vertically modular beehive that has the key features of vertically hung frames, a bottom board with entrance for the bees, boxes containing frames for brood and honey (the lowest box for the queen to lay eggs, and boxes above where honey may be stored) and an inner cover and top cap to provide weather protection. In a Langstroth hive, the bees build honeycomb into frames, which can be moved with ease. The frames are designed to prevent bees from attaching honeycombs where they would either connect adjacent frames, or connect frames to the walls of the hive. The movable frames allow the beekeeper to manage the bees in a way which was formerly impossible. The key innovation responsible for the hive's design was the discovery of bee space, a gap size of between in which bees would not build comb, nor would they close it with propolis. Modern Langstroth hives have different dimensions from L. L. Langstroth's beehive that wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petro Prokopovych
Petro Prokopovych (1775–1850, uk, Петро Прокопович) was a revolutionary Ukrainian beekeeper, the founder of commercial beekeeping and the inventor of the first movable frame hive. He introduced novelties in traditional beekeeping that allowed great progress in the practice. Among his most important inventions was a hive frame in a separate honey chamber of his beehive. He also invented a crude queen excluder between brood and honey chambers. Petro Prokopovych was also the first to ever model a 'bee beard' after delineating and calculating 'bee swarm behaviour", inspiring students for generations. Biography Prokopovych was born in Ukraine (then part of the Russian Empire), in the village of near Baturyn on June 29th, 1775 into a clerical family of priests of Ukrainian Cossack descent. Starting at the age of eleven, he studied at the Kyiv-Mohyla Academy for eight years. After studies he committed to a military career. He resigned his commission in 1798, bearing o ...

Beekeeping
Beekeeping (or apiculture) is the maintenance of bee colonies, commonly in man-made beehives. Honey bees in the genus '' Apis'' are the most-commonly-kept species but other honey-producing bees such as ''Melipona'' stingless bees are also kept. Beekeepers (or apiarists) keep bees to collect honey and other products of the hive: beeswax, propolis, bee pollen, and royal jelly. Pollination of crops, raising queens, and production of package bees for sale are other sources of beekeeping income. Bee hives are kept in an apiary or "bee yard". The keeping of bees by humans, primarily for honey production, began around 10,000 years ago. Georgia is known as the "cradle of beekeeping" and the oldest honey ever found comes from that country. The 5,500-year-old honey was unearthed from the grave of a noblewoman during archaeological excavations in 2003 near the town Borjomi. Ceramic jars found in the grave contained several types of honey, including linden and flower honey. Domestication of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beehive
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 (''Apis mellifera'') and the eastern honey bee (''Apis cerana'') are the main species kept in hives. The nest's internal structure is a densely packed group of hexagonal prismatic cells made of beeswax, called a honeycomb. The bees use the cells to store food (honey and pollen) and to house the brood (eggs, larvae, and pupae). Beehives serve several purposes: production of honey, pollination of nearby ...

Worker Bee
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 (outside of scientific literature) for any bees other than honey bees. Honey bee workers gather pollen into the pollen baskets on their back legs and carry it back to the hive where it is used as food for the developing brood. Pollen carried on their bodies may be carried to another flower where a small portion can rub off onto the pistil, resulting in cross pollination. A significant amount of the world's food supply, particularly fruit, depends greatly on crop pollination by honey bees. Nectar is sucked up through the proboscis, mixed with enzymes in the stomach, and carried back to the hive, where it is stored in wax cells and evaporated into honey. Life cycle Although the ...

Drone (bee)
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 a maiden queen in nuptial flight. Genetics Drones carry only one type of allele at each chromosomal position, because they are haploid (containing only one set of chromosomes from the mother). During the development of eggs within a queen, a diploid cell with 32 chromosomes divides to generate haploid cells called gametes with 16 chromosomes. The result is a haploid egg, with chromosomes having a new combination of alleles at the various loci. This process is called arrhenotokous parthenogenesis or simply arrhenotoky. Because the male bee technically has only a mother, and no father, its genealogical tree is unusual. The first generation has one member (the male). One generation back also has one member (the mother). Two generations back are two members (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beekeeper
A beekeeper is a person who keeps honey bees. Beekeepers are also called honey farmers, apiarists, or less commonly, apiculturists (both from the Latin '' apis'', bee; cf. apiary). The term beekeeper refers to a person who keeps honey bees in beehives, boxes, or other receptacles. The beekeeper does not control the creatures. The beekeeper owns the hives or boxes and associated equipment. The bees are free to forage or leave (swarm) as they desire. Bees usually return to the beekeeper's hive as the hive presents a clean, dark, sheltered home. Purposes of beekeeping Value of honey bees Honey bees produce commodities such as honey, beeswax, pollen, propolis, and royal jelly. Some beekeepers also raise queens and other bees to sell to other farmers, and to satisfy scientific curiosity. Beekeepers also use honeybees to provide pollination services to fruit and vegetable growers. Many people keep bees as a hobby. Others do it for income either as a sideline to other work or as a ...

Honey Super
A honey super is a part of a commercial or other managed (such as by a hobbyist) beehive that is used to collect honey. The most common variety is the "Illinois" or "medium" super with a depth of 6 inches, in the length and width dimensions of a Langstroth hive. A honey super consists of a box in which 8–10 frames are hung. Western honeybees collect nectar and store the processed nectar in honeycomb, which they build on the frames. When the honeycomb is full, the bees will reduce the moisture content of the honey to 17-18% moisture content before capping the comb with beeswax. Beekeepers will take the full honey supers and extract the honey. Periods when there is an abundant nectar source available and bees are quickly bringing back the nectar, are called a honey flow Honey flow is a term used by beekeepers indicating that one or more major nectar sources are in bloom and the weather is favorable for bees to fly and collect the nectar in abundance.

Autumn
Autumn, also known as fall in American English and Canadian English, is one of the four temperate seasons on Earth. Outside the tropics, autumn marks the transition from summer to winter, in September ( Northern Hemisphere) or March ( Southern Hemisphere). Autumn is the season when the duration of daylight becomes noticeably shorter and the temperature cools considerably. Day length decreases and night length increases as the season progresses until the Winter Solstice in December (Northern Hemisphere) and June (Southern Hemisphere). One of its main features in temperate climates is the striking change in colour for the leaves of deciduous trees as they prepare to shed. Date definitions Some cultures regard the autumnal equinox as "mid-autumn", while others with a longer temperature lag treat the equinox as the start of autumn. In the English-speaking world of high latitude countries, autumn traditionally began with Lammas Day and ended around Hallowe'en, the approxima ...

Winter Cluster
In beekeeping, a winter cluster is a well-defined cluster of honey bees that forms inside a beehive when the air temperature dips below 10 to 14 °C (50 to 57 F). Honey bees are one of but a few kinds of insects that survive the winter as a colony. As the outside air temperature decreases the winter cluster becomes tighter and more compact. The bees cling tightly together on the combs in the hive. The temperature within the winter cluster remains remarkably warm regardless of the outside air temperature. Larger clusters (basketball size) have a better chance for survival than smaller clusters (softball size). The winter cluster within the hive must move throughout the winter to reach the available honey stored in the combs. Some die-off is expected during the winter. In extended cold weather periods, the incidence of Nosema disease increases and the cluster may weaken as many bees begin dying off.Basil Furgala. 1975.

Hypothermia
Hypothermia is defined as a body core temperature below in humans. Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. In severe hypothermia, there may be hallucinations and paradoxical undressing, in which a person removes their clothing, as well as an increased risk of the heart stopping. Hypothermia has two main types of causes. It classically occurs from exposure to cold weather and cold water immersion. It may also occur from any condition that decreases heat production or increases heat loss. Commonly, this includes alcohol intoxication but may also include low blood sugar, anorexia and advanced age. Body temperature is usually maintained near a constant level of through thermoregulation. Efforts to increase body temperature involve shivering, increased voluntary activity, and putting on warmer clothing. Hypothermia may be diagnosed based on either a person ...

Pheromone
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are ''alarm signal, alarm pheromones'', ''food trail pheromones'', ''sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek φερω ''pheroo'' ('I carry') and ὁρμων ''hormon'' ('stimulating'). P ...
