Varroa Sensitive Hygiene
Varroa sensitive hygiene (VSH) is a behavioral trait of honey bees ''(Apis mellifera)'' in which bees detect and remove bee pupae that are infested by the parasitic mite ''Varroa destructor. V. destructor'' is considered to be the most dangerous pest problem for honey bees worldwide. VSH activity results in significant resistance to the mites. Subspecies with Varroa sensitive hygiene Some subspecies of ''Apis mellifera'' show naturally Varroa sensitive hygiene, for example '' Apis mellifera lamarckii'' and ''Apis mellifera carnica''. Development Bees with the VSH trait were initially bred by the United States Department of Agriculture Honey Bee Breeding, Genetics and Physiology Laboratory in Baton Rouge, Louisiana, from colonies in which mite populations grew only slowly.Harbo, J., and R. Hoopingarner. 1997. Honey Bees (Hymenoptera: Apidae) in the United States that express resistance to ''Varroa jacobsoni'' (Mesostigmata: Varroidae). Journal of Economic Entomology 90: 893-898. ...

Varroa Destructor On The Head Of Bee Nymph (5048084493)
''Varroa'' is a genus of parasitic mesostigmatan mites associated with honey bees, placed in its own family, Varroidae. The genus was named for Marcus Terentius Varro, a Roman scholar and beekeeper. The condition of a honeybee colony being infested with ''Varroa'' mites is called varroosis (also, incorrectly, ''varroatosis''). ''Varroa'' mites, specifically the species ''Varroa destructor'', are recognised as the biggest pest to honeybees worldwide due to their ability to transmit diseases such as deformed wing virus (or DWV) to larval or pupating bees, resulting in death or severe deformity of the pupae. History and behavior ''Varroa'' mites feed off the fat body tissue of adult, pupal, and larval honey bees, and may carry viruses that are particularly damaging to the bees (e.g., deformed wings, and IAPV), and accordingly they have been implicated in colony collapse disorder. Research has indicated that alone, neither ''Varroa'' mites nor deformed wing virus are particularly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miticides
Acaricides are pesticides that kill members of the arachnid subclass ''Acari'', which includes ticks and mites. Acaricides are used both in medicine and agriculture, although the desired selective toxicity differs between the two fields. Terminology More specific words are sometimes used, depending upon the targeted group: * "Ixodicides" are substances that kill ticks. * "Miticides" are substances that kill mites. *The term scabicide is more narrow, and refers to agents specifically targeting ''Sarcoptes''. *The term "arachnicide" is more general, and refers to agents that target arachnids. This term is used much more rarely, but occasionally appears in informal writing. As a practical matter, mites are a paraphyletic grouping, and mites and ticks are usually treated as a single group. Examples Examples include: * Permethrin can be applied as a spray. The effects are not limited to mites: lice, cockroaches, fleas, mosquitos, and other insects will be affected. * Ivermectin can ...

Buckfast Bees
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 n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breeder
A breeder is a person who selectively breeds carefully selected mates, normally of the same breed, to sexually reproduce offspring with specific, consistently replicable qualities and characteristics. This might be as a farmer, agriculturalist, or hobbyist, and can be practiced on a large or small scale, for food, fun, or profit. About A breeder can breed purebred pets such as cats or dogs, livestock such as cattle or horses, and may show their animals professionally in assorted forms of competitions. In these specific instances, the breeder strives to meet standards in each animal set out by organizations. A breeder may also assist with breeding animals in the zoo. In other cases, a breeder can be referred to an animal scientist who has the capabilities of developing more efficient ways to produce the meat and other animal products humans eat. Earnings as a breeder vary widely because of the various types of work involved in the job title. Even in breeding small domestic anim ...

Pollination
Pollination is the transfer of pollen from an anther of a plant to the stigma (botany), stigma of a plant, later enabling fertilisation and the production of seeds. Pollinating agents can be animals such as insects, for example bees, beetles or butterflies; birds, and bats; water; wind; and even plants themselves. Pollinating animals travel from plant to plant carrying pollen on their bodies in a vital interaction that allows the transfer of genetic material critical to the reproductive system of most flowering plants. Self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species, it can produce hybrid (biology), hybrid offspring in nature and in plant breeding work. In angiosperms, after the pollen grain (gametophyte) has landed on the stigma (botany), stigma, it germinates and develops a pollen tube which grows down the style (botany), style until it reaches an ovary (botany), ovary. Its two gametes travel down ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crop
A crop is a plant that can be grown and harvested extensively for profit or subsistence. In other words, a crop is a plant or plant product that is grown for a specific purpose such as food, Fiber, fibre, or fuel. When plants of the same species are cultivated in rows or other systematic arrangements, it is called crop field or crop cultivation. Most crops are harvested as food for humans or fodder for livestock. Important non-food crops include horticulture, floriculture, and industrial crops. Horticulture crops include plants used for other crops (e.g. fruit trees). Floriculture crops include bedding plants, houseplants, flowering garden and pot plants, cut cultivated greens, and cut flowers. Industrial crops are produced for clothing (fiber crops e.g. cotton), biofuel (energy crops, algae fuel), or medicine (medicinal plants). Production There was an increase in global production of primary crops by 56% between 2000 and 2022 to 9.6 billion tonnes, which represents a 0 ...

Italian Bee
The Italian bee or Italian Honey bee (''Apis mellifera ligustica'') is a subspecies of the western honey bee (''Apis mellifera''). Origin The Italian honey bee is endemic to the continental part of Italy, south of the Alps, and north of Sicily, where it survived the Last Glacial Period, last ice age. On Sicily the subspecies is ''Apis mellifera siciliana''. It is likely the most commercially distributed of all honey bees, and has proven adaptable to most climates from subtropical to cool temperate, but it is less successful in humid tropical regions. Italian bees that originate from the Ligurian alps in northern Italy are often referred to as the Ligurian bee, which is claimed only survives on Kangaroo Island. Italian bees, having been conditioned to the warmer climate of the central Mediterranean, are less able to cope with the "hard" winters and cool, wet springs of more northern latitudes. They do not form such tight winter clusters. More food has to be consumed to compensate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honey
Honey is a sweet and viscous substance made by several species of bees, the best-known of which are honey bees. Honey is made and stored to nourish bee colonies. Bees produce honey by gathering and then refining the sugary secretions of plants (primarily floral nectar) or the secretions of other insects, like the honeydew of aphids. This refinement takes place both within individual bees, through regurgitation and enzymatic activity, and during storage in the hive, through water evaporation that concentrates the honey's sugars until it is thick and viscous. Honey bees stockpile honey in the hive. Within the hive is a structure made from wax called honeycomb. The honeycomb is made up of hundreds or thousands of hexagonal cells, into which the bees regurgitate honey for storage. Other honey-producing species of bee store the substance in different structures, such as the pots made of wax and resin used by the stingless bee. Honey for human consumption is collected ...

Beekeeping
Beekeeping (or apiculture, from ) is the maintenance of bee colonies, commonly in artificial 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. Other sources of beekeeping income include pollination of crops, raising queens, and production of package bees for sale. Bee hives are kept in an apiary or "bee yard". The earliest evidence of humans collecting honey are from Spanish caves paintings dated 6,000 BCE, however it is not until 3,100 BCE that there is evidence from Egypt of beekeeping being practiced. In the modern era, beekeeping is often used for crop pollination and the collection of its by products, such as wax and propolis. The largest beekeeping operations are agricultural businesses but many small beekeeping operations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outcrossing
Out-crossing or out-breeding is the technique of crossing between different breeds. This is the practice of introducing distantly related genetic material into a breeding line, thereby increasing genetic diversity. Outcrossing in animals Outcrossing can be a useful technique in animal breeding. The outcrossing breeder intends to remove the traits by using "new blood." With dominant traits, one can still see the expression of the traits and can remove those traits, whether one outcrosses, line breeds or inbreeds. With recessive traits, outcrossing allows for the recessive traits to migrate across a population. Many traits are Mendelian and therefore exhibit a more complicated intermediate phenotype. The outcrossing breeder then may have individuals that have many deleterious genes that may be expressed by subsequent inbreeding. There is now a gamut of deleterious genes within each individual in many dog breeds. Increasing the variation of genes or alleles within the gene poo ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...
