Stingless Bee
Stingless bees (SB), sometimes called stingless honey bees or simply meliponines, are a large group of bees (from about 462 to 552 described species), comprising the Tribe (biology), tribe Meliponini (or subtribe Meliponina according to other authors). They belong in the Family (biology), family Apidae (subfamily Apinae), and are closely related to common honey bees (HB, tribe Apini), orchid bees (tribe Euglossini), and bumblebees (tribe Bombini). These four bee tribes belong to the Pollen basket, corbiculate bees Monophyly, monophyletic group. Meliponines have stingers, but they are highly reduced and cannot be used for defense, though these bees exhibit other defensive behaviors and mechanisms. Meliponines are not the only type of bee incapable of stinging: all male bees and many female bees of several other families, such as Andrenidae and Megachilidae (tribe Dioxyini), also cannot sting. Some stingless bees have powerful mandibles and can inflict painful bites. Some species ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Resin
A resin is a solid or highly viscous liquid that can be converted into a polymer. Resins may be biological or synthetic in origin, but are typically harvested from plants. Resins are mixtures of organic compounds, predominantly terpenes. Common resins include amber, hashish, frankincense, myrrh and the animal-derived resin, shellac. Resins are used in varnishes, adhesives, food additives, incenses and perfumes. Resins protect plants from insects and pathogens, and are secreted in response to injury. Resins repel herbivores, insects, and pathogens, while the volatile natural phenol, phenolic compounds may attract benefactors such as predators of insects that attack the plant. Composition Most plant resins are composed of terpenes. Specific components are alpha-Pinene, alpha-pinene, pinene, beta-pinene, carene, delta-3 carene, and sabinene, the monocyclic terpenes limonene and terpinolene, and smaller amounts of the tricyclic sesquiterpenes, longifolene, caryophyllene, and cad ...

Totarol
Totarol is a naturally produced diterpene that is bioactive. It was first isolated by McDowell and Easterfield from the heartwood of ''Podocarpus totara'', an endemic conifer species found in New Zealand. ''Podocarpus totara'' was investigated for unique molecules due to the tree's increased resistance to rotting. Recent studies have confirmed totarol's unique antimicrobial and therapeutic properties. Consequently, totarol is a candidate for a new source of drugs and has been the goal of numerous syntheses. Discovery Totarol was discovered in 1910 by New Zealand scientist Sir Thomas Hill Easterfield. While investigating the properties of '' Miro'', ''Kahikatea'', ''Rimu'', '' Matai'' and ''Tōtara'', Easterfield detected a "crystalline bloom" on tōtara boards a few hours after leaving the planing machine. After extraction of totarol from ''Podocarpus totara,'' Easterfield observed no other compound had been cited in chemical literature before with this formula. Easterfiel ...

Hymenoptera Of South America
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they reach adulthood. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
