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 ...

Top Bar Hive
A top-bar hive is a single-story frameless beehive in which the comb hangs from removable bars. The bars form a continuous roof over the comb, whereas the frames in most current hives allow space for bees to move up or down between boxes. Hives that have frames or that use honey chambers in summer but which use management principles similar to those of regular top-bar hives are sometimes also referred to as top-bar hives. Top-bar hives are rectangular in shape and are typically more than twice as wide as multi-story framed hives commonly found in English-speaking countries. Top-bar hives usually include one box only, and allow for beekeeping methods that interfere very little with the colony. While conventional advice often recommends inspecting each colony each week during the warmer months, heavy work when full supers have to be lifted, some beekeepers fully inspect top-bar hives only once a year, and only one comb needs to be lifted at a time.

Kin Selection
Kin selection is the evolutionary strategy that favours the reproductive success of an organism's relatives, even when at a cost to the organism's own survival and reproduction. Kin altruism can look like altruistic behaviour whose evolution is driven by kin selection. Kin selection is an instance of inclusive fitness, which combines the number of offspring produced with the number an individual can ensure the production of by supporting others, such as siblings. 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 same "stock") would allow the evolution of a trait that confers the benefit but destroys an individual at the same time. R.A. Fisher in 1930 and J.B.S. Haldane in 1932 set out the mathematics of kin selection, with Haldane famously joki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollen Source
The term pollen source is often used in the context of beekeeping and refers to flowering plants as a source of pollen for bees or other insects. Bees collect pollen as a protein source to raise their brood. For the plant, the pollinizer, this can be an important mechanism for sexual reproduction, as the pollinator distributes its pollen. Few flowering plants self-pollinate; some can provide their own pollen (self fertile), but require a pollinator to move the pollen; others are dependent on cross pollination from a genetically different source of viable pollen, through the activity of pollinators. One of the possible pollinators to assist in cross-pollination are honeybees. The article below is mainly about the pollen source from a beekeeping perspective. The pollen source in a given area depends on the type of vegetation present and the length of their bloom period. What type of vegetation will grow in an area depends on soil texture, soil pH, soil drainage, daily maxi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nectar Source
A nectar source is a flowering plant that produces nectar as part of its reproductive strategy. These plants create nectar, which attract pollinating insects and sometimes other animals such as birds. Nectar source plants are important for beekeeping, as well as in agriculture and horticulture. Their use is particularly important for organic agriculture and organic horticulture, where they serve not only to attract pollinators for crops, but also provide habitat for beneficial insects and other animals that provide pest control. In gardens, nectar sources are often provided to attract butterflies and hummingbirds as well. For honey bees While many plants produce nectar, beekeepers prefer to place their hives near certain plants, for the qualities of the honey produced. Certain agricultural crops, such as clover and buckwheat, are used to make specific honeys, which often command a premium price. Some plants are avoided by some beekeepers (and sought out by others) due to su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forage (honey Bee)
For bees, their forage or food supply consists of nectar and pollen from blooming plants within flight range. The forage sources for honey bees are an important consideration for beekeepers. In order to determine where to locate hives for maximum honey production and 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 for 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 life cycle and colony activity. As a rule of thumb the foraging area around a beehive extends for , although bees have been observed foraging twice and three times this distance from the hive. ...

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, chipisas, virgencitas,'' and ''mariolitas''). A subspecies, ''Tetragonisca angustula fiebrigi'', occupies different areas in South America and has a slightly different coloration. ''T. 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 than the workers.

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 ...

Propolis
Propolis or bee glue is a resinous mixture that honey bees produce by mixing saliva and beeswax with exudate gathered from tree buds, sap flows, or other botanical sources. It is used as a sealant for unwanted open spaces in the beehive. Propolis is used for small gaps (approximately or less), while gaps larger than the bee space (approximately ) are usually filled with burr comb. Its color varies depending on its botanical source, with dark brown as the most common. Propolis is sticky at and above , while at lower temperatures it becomes hard and brittle. When foraging, worker bees primarily harvest pollen and nectar, while also collecting water and plant resin necessary for the production of propolis. The chemical composition and nature of propolis depend on environmental conditions and harvested resources. Types Mixed types of propolis found in European countries with a moderate climate include two or more sources of plant resins (plant species) identified by composition ...

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 Three 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 lipas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
