Worker (bee)
A worker bee is any female bee that lacks the reproductive capacity of the colony's queen bee and carries out the majority of tasks needed for the functioning of the hive. While worker bees are present in all eusocial bee species, the term is rarely used (outside of scientific literature) for bees other than honey bees, particularly the European honey bee (''Apis mellifera''). Worker bees of this variety are responsible for approximately 80% of the world's crop pollination services. Worker bees are the caste of bee that perform most of the fundamental tasks of the hive, and they are by far the most numerous type of bee. They are much smaller than drones or queen bees, with bodies specialized for nectar and pollen collection. They perform different tasks around the hive progressively over their lifespans in a predictable order based on their age. Worker bees gather pollen in the pollen baskets on their back legs and carry it back to the hive where it is used as food for the devel ...

Forage (honey Bee)
For bees, their forage or food supply consists of nectar and pollen from flower, blooming plants within their flight range. The forage sources for Western honey bee, honey bees are an important consideration for beekeepers. In order to determine where to locate hives for maximum honey production and brood (honeybee), brood one must consider the off-season. If there are no honey flows the bees may have to be fed. Bees that are used for commercial pollination are usually fed in the holding yards. Forage is also significant for pollination management with other bee species. Nectar contains sugars that are the primary source of energy for the bees' wing muscles and for heat for honey bee colonies during the winter. Pollen provides the protein and trace minerals that are mostly fed to the brood in order to replace bees lost in the normal course of their life cycle and colony activity. As a rule of thumb, the foraging area around a beehive (beekeeping), beehive extends for , althoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bee Sting
A bee sting is the wound and pain caused by the stinger of a female bee puncturing skin. Bee stings differ from Insect bites and stings, insect bites, with the venom of stinging insects having considerable chemical variation. The reaction of a person to a bee sting may vary according to the bee species. While bee stinger venom is slightly acidic and causes only mild pain in most people, allergic reactions may occur in people with allergies to venom components. Honey bee stings A honey bee that is away from the hive foraging for nectar or pollen will rarely sting, except when stepped on or roughly handled. Honey bees will actively seek out and sting when they perceive the Beehive (beekeeping), hive to be threatened, often being alerted to this by the release of attack pheromones (below). Although it is widely believed that a worker bee, worker honey bee can sting only once, this is a partial misconception: although the stinger is in fact barbed so that it lodges in the victim's ...

Laying Worker Bee
A laying worker bee is a worker bee that lays fertilization, unfertilized eggs, usually in the absence of a queen bee. Only Drone (bee), drones develop from the egg (biology), eggs of laying worker bees (with some exceptions, see thelytoky). A beehive (beekeeping), beehive cannot survive with only a laying worker bee. Prevalence Even in a normal hive, about 1% of workers have ovaries developed enough to lay eggs. However the usual number of the laid eggs is very small. Only eight eggs (seven moderately and one fully developed) were found after examining of 10,634 worker bees (strong colony contains about 100,000). Workers eventually lay significant numbers of eggs only in queenless colonies. Development Laying workers develop in the absence of open brood as produced by a healthy adult queen. Normally, pheromones from the brood – known as Pheromone (honeybee)#Brood recognition pheromone, brood recognition pheromones – prevent development of the workers' ovar ...

Kin Selection
Kin selection is a process whereby natural selection favours a trait due to its positive effects on the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction. Kin selection can lead to the evolution of Altruism in animals, altruistic behaviour. It is related to inclusive fitness, which combines the number of offspring produced with the number an individual can ensure the production of by supporting others (weighted by the relatedness between individuals). A broader definition of kin selection includes selection acting on interactions between individuals who share a gene of interest even if the gene is not shared due to common ancestry. Charles Darwin discussed the concept of kin selection in his 1859 book, ''On the Origin of Species'', where he reflected on the puzzle of sterile social insects, such as honey bees, which leave reproduction to their mothers, arguing that a selection benefit to related organisms (the sam ...

Schwarziana Quadripunctata
''Schwarziana quadripunctata'' is a small, stingless bee found in a stretch of the South American Amazon from Goiás, Brazil, through Paraguay, to Misiones, Argentina.Michener, C.D. (2007). ''The Bees of the World''. Baltimore: Johns Hopkins University Press. This highly eusocial insect constructs earthen nests in the subterranean level of the subtropical environment, an unusual feature among other stingless bees. The species ranges in sizes from and feeds on a diverse diet of flowering plants found abundantly on the forest floor, including guacatonga ('' Casearia sylvestris'') and the mistletoe species '' Struthanthus concinnus''. Taxonomy and phylogeny ''Schwarziana quadripunctata'' was first described by the French entomologist and former president of the French Entomologist Society Amédéé Louis Michel le Peletier in 1836. Although originally placed in the genus ''Trigona'', more recent taxonomic evaluations have since placed it under its current genus, following the 19 ...

Tetragonisca Angustula
''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 (e.g., '' jataí, yatei, jaty, virginitas, angelitas inglesas, españolita, mariola, ramichi, chipisas, virgencitas,'' and ''mariolitas''). A subspecies, ''Tetragonisca angustula fiebrigi'', occupies different areas in South America and has a slightly different coloration. ''Tetragonisca angustula'' is a very small bee and builds unobtrusive nests, allowing it to thrive in urban areas. It also produces large amounts of honey, and is thus frequently kept in wooden hives by beekeepers. ''T. angustula'' hives are often overlooked, and since the bee lacks a stinger, it is not seen as a threat to humans. Many of their behaviors are concerned with colonizing a new nest and producing offspring, demonstrated by their swarming and nursing behaviors, however a special caste of ''T. angustula'' are soldiers who are slightly larger t ...

Wasp
A wasp is any insect of the narrow-waisted suborder Apocrita of the order Hymenoptera which is neither a bee nor an ant; this excludes the broad-waisted sawflies (Symphyta), which look somewhat like wasps, but are in a separate suborder. The wasps do not constitute a clade, a complete natural group with a single ancestor, as bees and ants are deeply nested within the wasps, having evolved from wasp ancestors. Wasps that are members of the clade Aculeata can sting their prey. The most commonly known wasps, such as yellowjackets and hornets, are in the family Vespidae and are eusocial, living together in a nest with an egg-laying queen and non-reproducing workers. Eusociality is favoured by the unusual haplodiploid system of sex determination in Hymenoptera, as it makes sisters exceptionally closely related to each other. However, the majority of wasp species are solitary, with each adult female living and breeding independently. Females typically have an oviposit ...

Melipona Scutellaris
''Melipona scutellaris'' is a eusocial stingless bee species of the order Hymenoptera and the genus ''Melipona''. It is considered to be the reared ''Melipona'' species with the largest distribution in the North and Northeast regions of Brazil, with records from Rio Grande do Norte down to Bahia. Its common name, Uruçu, comes from the Tupi "eiru su", which in this indigenous language means "big bee". Their honey is highly desirable and the materials they create for nests have been proven to be a promising source of antibiofilm agents and to present selectivity against human cancer cell lines at low concentrations compared to normal cells. Taxonomy ''M. scutellaris'' is a member of the family Apidae of eusocial bees within the order Hymenoptera, which consists of ants, bees, wasps, and sawflies. The subfamily Meliponini is commonly referred to as "stingless bees". It is one of 40 known species within the genus ''Melipona''. ''M. scutellaris'' has the common name of "uruçu-norde ...

Rancidification
Rancidification is the process of complete or incomplete autoxidation or hydrolysis of fats and oils when exposed to air, light, moisture, or bacterial action, producing short-chain aldehydes, ketones and free fatty acids. When these processes occur in food, undesirable odors and flavors can result. In processed meats, these flavors are collectively known as warmed-over flavor. In certain cases, however, the flavors can be desirable (as in aged cheeses). Rancidification can also detract from the nutritional value of food, as some vitamins are sensitive to oxidation. Similar to rancidification, oxidative degradation also occurs in other hydrocarbons, such as lubricating oils, fuels, and mechanical cutting fluids. Pathways Five pathways for rancidification are recognized: Hydrolytic Hydrolytic rancidity refers to the odor that develops when triglycerides are hydrolyzed and free fatty acids are released. This reaction of lipid with water may require a catalyst (such as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
