Bee Diseases
Diseases of the honey bee or abnormal hive conditions include: Pests and parasites ''Varroa'' mites ''Varroa destructor'' and ''V. jacobsoni'' are parasitic mites that feed on the fat bodies of adult, pupal and larval bees. When the hive is very heavily infested, ''Varroa'' mites can be seen with the naked eye as a small red or brown spot on the bee's thorax. ''Varroa'' mites are carriers for many viruses that are damaging to bees. For example, bees infected during their development will often have visibly deformed wings. ''Varroa'' mites have led to the virtual elimination of feral bee colonies in many areas, and are a major problem for kept bees in apiaries. Some feral populations are now recovering—it appears they have been naturally selected for ''Varroa'' resistance. ''Varroa'' mites were first discovered in Southeast Asia in about 1904, but are now present on all continents except Australia. They were discovered in the United States in 1987, in New Zealand in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disease
A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, or death to the person affected, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structur ...

Colony Collapse Disorder
Colony collapse disorder (CCD) is an abnormal phenomenon that occurs when the majority of worker bees in a honey bee colony disappear, leaving behind a queen, plenty of food, and a few nurse bees to care for the remaining immature bees. While such disappearances have occurred sporadically throughout the history of apiculture, and have been known by various names (including disappearing disease, spring dwindle, May disease, autumn collapse, and fall dwindle disease), the syndrome was renamed colony collapse disorder in early 2007 in conjunction with a drastic rise in reports of disappearances of western honey bee (''Apis mellifera'') colonies in North America. Beekeepers in most European countries had observed a similar phenomenon since 1998, especially in Southern and Western Europe; the Northern Ireland Assembly received reports of a decline greater than 50%. The phenomenon became more global when it affected some Asian and African countries as well. Colony collapse disorder co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buckfast Bee
The Buckfast bee is a breed of honey bee, a cross of many subspecies and their strains, developed by Brother Adam (born Karl Kehrle in 1898 in Germany), who was in charge of beekeeping from 1919 at Buckfast Abbey in Devon in the United Kingdom. Breeding of the Buckfast bee is now done by breeders throughout Europe belonging to the ''Federation of European Buckfast Beekeepers'' (G.D.E.B.). This organization maintains a pedigree for Buckfast bees, originating from the time of Brother Adam. In 1916, only 16 surviving colonies were left in the abbey. All of them were either pure Ligurian (Italian) or of Ligurian origin, hybrids between Ligurian and the English black bee '' A. m. mellifera''. Brother Adam also imported some more Italian queens. From these, he began to develop what would come to be known as the Buckfast bee. Origin and Heritage According to Brother Adam's personal notes, 1915 was "The last season colonies of the former native honeybee (the British strain of ''A. m ...

Buckfast Abbey
Buckfast Abbey forms part of an active Benedictine monastery at Buckfast, near Buckfastleigh, Devon, England. Buckfast first became home to an abbey in 1018. The first Benedictine abbey was followed by a Savignac (later Cistercian) abbey constructed on the site of the current abbey in 1134. The monastery was surrendered for dissolution in 1539, with the monastic buildings stripped and left as ruins, before being finally demolished. The former abbey site was used as a quarry, and later became home to a Gothic mansion house. In 1882 the site was purchased by a group of French Benedictine monks, who refounded a monastery on the site, dedicated to Saint Mary. New monastic buildings and a temporary church were constructed incorporating the existing Gothic house. Buckfast was formally reinstated as an Abbey in 1902, and the first abbot of the new institution, Boniface Natter, was blessed in 1903. Work on a new abbey church, which was constructed mostly on the footprint of the form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brother Adam
Karl Kehrle OSB OBE (3 August 1898, Mittelbiberach, Germany – 1 September 1996, Buckfast, Devonshire, England, UK), known as Brother Adam, was a Benedictine monk, beekeeper, and an authority on bee breeding, developer of the Buckfast bee. "He was unsurpassed as a breeder of bees. He talked to them, he stroked them. He brought to the hives a calmness that, according to those who saw him at work, the sensitive bees responded to." – ''The Economist'', 14 September 1996 Biography Due to health problems Kehrle was sent by his mother at age 11 from Germany to Buckfast Abbey, where he joined the order (becoming ''Brother Adam'') and in 1915 started his beekeeping activity. Two years before, a parasite, ''Acarapis woodi'' that originated on the Isle of Wight had started to extend over the country, devastating all the native bees, and in 1916 it reached the abbey, killing 30 of the 46 bee colonies. He travelled to Turkey to find resistant native bees for selective br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acarapis Woodi
''Acarapis woodi'' is an internal parasite affecting honey bees, the symptoms of infestation was originally observed on the Isle of Wight in 1904, but was not species description, described until 1921. ''Acarapis woodi'' mites live and reproduce in the invertebrate trachea, tracheae of the bees. The symptoms of ''Acarapis woodi'' infestation were originally called by beekeepers as the ''Isle of Wight Disease'', however it is now called List of diseases of the honey bee#Acarine (tracheal) mites, Acarine, after the Subclass to which the mites belong. All mites are arachnida, arachnids like spiders. The female mite attaches 5–7 eggs to the tracheal walls, where the larvae hatch and develop in 11–15 days to adult mites. The mites parasitize young bees up to two weeks old through the tracheal tube openings. There, they pierce the tracheal tube walls with their Arthropod mouthparts, mouthparts and feed on the hemolymph, haemolymph of the bees. More than a hundred mites can populate ...

Formic Acid
Formic acid (), systematically named methanoic acid, is the simplest carboxylic acid, and has the chemical formula HCOOH and structure . It is an important intermediate in chemical synthesis and occurs naturally, most notably in some ants. Esters, salts and the anion derived from formic acid are called formates. Industrially, formic acid is produced from methanol. Natural occurrence In nature, formic acid is found in most ants and in stingless bees of the genus ''Oxytrigona''. Wood ants from the genus ''Formica'' can spray formic acid on their prey or to defend the nest. The puss moth caterpillar (''Cerura vinula'') will spray it as well when threatened by predators. It is also found in the trichomes of stinging nettle (''Urtica dioica''). Apart from that, this acid is incorporated in many fruits such as pineapple (0.21mg per 100g), apple (2mg per 100g) and kiwi (1mg per 100g), as well as in many vegetables, namely onion (45mg per 100g), eggplant (1.34 mg per 100g) and, in ...

Oxalic Acid
Oxalic acid is an organic acid with the systematic name ethanedioic acid and formula . It is the simplest dicarboxylic acid. It is a white crystalline solid that forms a colorless solution in water. Its name comes from the fact that early investigators isolated oxalic acid from flowering plants of the genus ''Oxalis'', commonly known as wood-sorrels. It occurs naturally in many foods. Excessive ingestion of oxalic acid or prolonged skin contact can be dangerous. Oxalic acid has much greater acid strength than acetic acid. It is a reducing agent and its conjugate base, known as oxalate (), is a chelating agent for metal cations. Typically, oxalic acid occurs as the dihydrate with the formula . History The preparation of salts of oxalic acid (crab acid) from plants had been known, at least since 1745, when the Dutch botanist and physician Herman Boerhaave isolated a salt from wood sorrel. By 1773, François Pierre Savary of Fribourg, Switzerland had isolated oxalic acid from i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flumethrin
Flumethrin is a pyrethroid insecticide. It is used externally in veterinary medicine against parasitic insects and ticks on cattle, sheep, goats, horses, and dogs, and the treatment of parasitic mites in honeybee colonies. Chemistry Flumethrin is a complex mixture of stereoisomers. The molecule contains three asymmetric carbon atoms, there is cis-trans isomerism at the cyclopropane ring, and cis-trans isomerism at the carbon-carbon double bond of the alkene. So there are 16 different isomers. Commercial flumethrin typically contains 92% of the trans isomers on the cyclopropane ring and the cis-configuration at the olefinic carbon-carbon double bond and 8% of the isomer with cis geometry on the cyclopropane ring and the cis-configuration at the olefinic carbon-carbon double bond. Uses Flumethrin is used in products, such as flea and tick collars, to protect pets against fleas. It is also used in the proprietary product, ″Bayvarol″, ″Polyvar Yellow″ which are veterinar ...

Coumaphos
Coumaphos is a nonvolatile, fat-soluble phosphorothioate with ectoparasiticide properties: it kills insects and mites. It is well known by a variety of brand names as a dip or wash, used on farm and domestic animals to control ticks, mites, flies and fleas. It is also used to control ''Varroa'' mites in honey bee colonies, though in many areas it is falling out of favor as the mites develop resistance and as the residual toxicity effects are becoming better understood. In Australia, its registration as suited to home veterinary use was cancelled by the Australian Pesticides and Veterinary Medicines Authority in June 2004 after the manufacturer failed to show it was safe for use on pets. The compound has been linked to neurological problems in bees, and may be a factor in colony collapse. It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act The Emergency Planning ...

Fluvalinate
Fluvalinate is a synthetic pyrethroid chemical compound contained as an active agent in the products Apistan, Klartan, and Minadox, that is an acaricide (specifically, a miticide), commonly used to control ''Varroa'' mites in honey bee colonies, infestations that constitute a significant disease of such insects. Fluvalinate is a stable, nonvolatile, viscous, heavy oil (technical) soluble in organic solvents. Although the compound may be found in drones, a study has found honey samples virtually absent of fluvalinate, on account of its affinity to beeswax. Stereoisomerism Fluvalinate is synthesized from racemic valine RS)-valine the synthesis is not diastereoselective. Thus, fluvalinate is a mixture of four stereoisomers, each about 25%. ''Tau''-fluvalinate (τ-fluvalinate) is the trivial name for (2''R'')-fluvalinate. The C atom in the valinate structure is in (''R'')-absolute configuration, while the second chiral atom is a mixture of (''R'')- and (''S'')-configurati ...
