Diseases Of The Honeybee
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, following their introduction to Australia in 2022. They were discovered in the United S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disease
A disease is a particular abnormal condition that adversely affects the structure or function (biology), function of all or part of an organism and 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, allergy, allergies, and autoimmune disorders. In humans, ''disease'' is often used more broadly to refer to any condition that causes pain, Abnormality (behavior), dysfunction, distress (medicine), 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 injury in humans, injuries, disability, disabilities, Disorder (medicine) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thymol
Thymol (also known as 2-isopropyl-5-methylphenol, IPMP), , is a toxic monoterpenoid phenol derivative of ''p''-Cymene, isomeric with carvacrol. It occurs naturally in the oil of thyme, and it is extracted from ''Thymus vulgaris'' (common thyme), ajwain, and various other plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties. Thymol also provides the distinctive, strong flavor of the culinary herb thyme, also produced from ''T. vulgaris''. Thymol is only slightly soluble in water at neutral pH, but it is extremely soluble in alcohols and other organic solvents. It is also soluble in strongly alkaline aqueous solutions due to deprotonation of the phenol. Its dissociation constant ( p''K''a) is . Thymol absorbs maximum UV radiation at 274 nm. Chemical synthesis Thymol is produced by the alkylation of ''m''-cresol and propene: : A predicted method of biosynthesis of thymol in thyme and oregano begins with the cyclizati ...

Dissection
Dissection (from Latin ' "to cut to pieces"; also called anatomization) is the dismembering of the body of a deceased animal or plant to study its anatomical structure. Autopsy is used in pathology and forensic medicine to determine the cause of death in humans. Less extensive dissection of plants and smaller animals preserved in a formaldehyde solution is typically carried out or demonstrated in biology and natural science classes in middle school and high school, while extensive dissections of cadavers of adults and children, both fresh and preserved are carried out by medical students in medical schools as a part of the teaching in subjects such as anatomy, pathology and forensic medicine. Consequently, dissection is typically conducted in a morgue or in an anatomy lab. Dissection has been used for centuries to explore anatomy. Objections to the use of cadavers have led to the use of alternatives including virtual dissection of computational anatomy, computer models. In the ...

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 Ligurian ('' A. m. ligustica'') from Italy or Ligurian queens mated with the English black bee ' A. m. mellifera''; by 1919 these bees too had died causing Brother Adam to import queens again from Italy and also France, from which 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Congregation of Savigny, Savignac, later Cistercian, abbey constructed on the site of the current abbey in 1134. The monastery was largely demolished after its Dissolution of the Monasteries, dissolution in 1539. In 1882 the site was purchased by French Benedictines who refounded a monastery on the site. New monastic buildings incorporated the remaining Gothic house. Buckfast was formally reinstated as an abbey in 1902. Work on a new abbey church, which was constructed mostly on the footprint of the former Cistercian abbey, started in 1907. The church was completed in 1938. As of 2020, the abbey has 13 monks. History Early history The first abbey at Buckfast was founded as a Benedictine Order, Benedictine monastery in 1018.Beattie 83. The abbey was believed to be founded by eit ...

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 the age of 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 selectiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acarapis Woodi
''Acarapis woodi'' is an internal parasite affecting honey bees, the symptoms of infestation were originally observed on the Isle of Wight in 1904, but was not described until 1921. ''Acarapis woodi'' mites live and reproduce in the 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 Acarine, after the subclass to which the mites belong. All mites are 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 mouthparts and feed on the haemolymph Hemolymph, or haemolymph, is a fluid, similar to the blood in invertebrates, that circulates in the inside of the arthropod's body, remaining in direct contact with the animal's tissues. ...

Formic Acid
Formic acid (), systematically named methanoic acid, is the simplest carboxylic acid. It has the chemical formula HCOOH and structure . This acid 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 Formic acid, which has a pungent, penetrating odor, is found naturally in insects, weeds, fruits and vegetables, and forest emissions. It appears 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 (0.21 mg per 100 g), apple (2 mg per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxalic Acid
Oxalic acid is an organic acid with the systematic name ethanedioic acid and chemical formula , also written as or or . It is the simplest dicarboxylic acid. It is a white crystalline solid that forms a colorless solution in water. Its name is derived from early investigators who 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 is a much stronger acid than acetic acid. It is a reducing agent and its conjugate bases hydrogen oxalate () and oxalate () are chelating agents for metal cations. It is used as a cleaning agent, especially for the removal of rust, because it forms a water-soluble ferric iron complex, the ferrioxalate ion. Oxalic acid typically occurs as the dihydrate with the formula . History The preparation of salts of oxalic acid from plants had been known since at least 1745, when ...

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 Plannin ...

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, ''Varroa'' mites in honey bee colonies, infestations that constitute a significant Diseases of the honeybee, disease of such insects. Fluvalinate is a stable, nonvolatile, viscous, heavy oil (technical) soluble in organic solvents. Although the compound may be found in Drone (bee), drones, a study has found honey samples virtually absent of fluvalinate, on account of its affinity to beeswax. CHS Health Classification Fluvalinate is considered an acute toxic, Health hazard and environmental hazard by ECHA (European Chemicals Agency). The chemical is fatal if inhaled and is extremally toxic to aquatic life. If not fatal the effects are permanent and has multiple long lasting effects. Stereoisomerism Fluvalinate is synthesized from Racemate, racemic valine [( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
