Nasonov Pheromone
The Nasonov (alternatively, Nasanov) pheromone is released by worker bees to orient returning forager bees back to the colony. To broadcast this scent, bees raise their abdomens, which contain the Nasonov glands, and fan their wings vigorously. Nasonov includes a number of different terpenoids including geraniol, nerolic acid, citral and geranic acid. Bees use these to find the entrance to their colony or hive, and they release them on flowers so other bees know which flowers have nectar. Once the foraging bee leaves the nest it uses its sense from special sensing cells on the antennae to locate and distinguish forage plants, which each give off a unique blend of odour chemicals. When a beekeeper lifts out frames from a hive they disturb the balance of smells within the hive. It can take up to 48 hours for the colony to re-establish its scent equilibrium. A synthetically produced Nasonov pheromone can be used to attract a honey bee swarm to an unoccupied hive or a swarm-ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geranic Acid
Geranic acid, or 3,7-dimethyl-2,6-octadienoic acid, is a pheromone A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavio ... used by some organisms. It is a double bond isomer of nerolic acid. Pharmacology Choline geranate (also described as Choline And Geranic acid, or CAGE) has been developed as a novel biocompatible antiseptic material capable of penetrating skin and aiding the transdermal delivery of co-administered antibiotics. The antibacterial properties of CAGE were analyzed against 24 and 72 hour old biofilms of 11 clinically isolated ESKAPE pathogens (defined as Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumanii, Pseudomonas aeruginosa, and Enterobacter sp, respectively), including multidrug resistant (MDR) isolates. CAGE was observ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bee Ecology
Bees are winged insects closely related to wasps and ants, known for their roles in pollination and, in the case of the best-known bee species, the western honey bee, for producing honey. Bees are a monophyletic lineage within the superfamily Apoidea. They are presently considered a clade, called Anthophila. There are over 16,000 known species of bees in seven recognized biological families. Some speciesincluding honey bees, bumblebees, and stingless beeslive socially in colonies while most species (>90%)including mason bees, carpenter bees, leafcutter bees, and sweat beesare solitary. Bees are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants. The most common bees in the Northern Hemisphere are the Halictidae, or sweat bees, but they are small and often mistaken for wasps or flies. Bees range in size from tiny stingless bee species, whose workers are less than long, to '' Megachile pluto' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beekeeping
Beekeeping (or apiculture) is the maintenance of bee colonies, commonly in man-made 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. Pollination of crops, raising queens, and production of package bees for sale are other sources of beekeeping income. Bee hives are kept in an apiary or "bee yard". The keeping of bees by humans, primarily for honey production, began around 10,000 years ago. Georgia is known as the "cradle of beekeeping" and the oldest honey ever found comes from that country. The 5,500-year-old honey was unearthed from the grave of a noblewoman during archaeological excavations in 2003 near the town Borjomi. Ceramic jars found in the grave contained several types of honey, including linden and flower honey. Domestication of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nasonov's Gland
Nasonov's gland produces a pheromone used in recruitment in worker honeybees. The pheromone can serve the purposes of attracting workers to a settled swarm and draw bees who have lost their way back to the hive. It is used to recruit workers to food that lacks a characteristic scent and lead bees to water sources. The gland is located on the dorsal side of the abdomen. Its opening is located at the base of the last tergite at the tip of the abdomen. The gland was first described in 1882 by the Russian zoologist Nikolai Viktorovich Nasonov (February 14, 1855 – February 11, 1939). Nasonov thought that the gland performed perspiration; it was Frederick William Lambert Sladen (May 30, 1876 - 1921) of England who in 1901 first proposed that the gland produced a pheromone.See: * (Snodgrass, 1925), p. 116. * * Republished in condensed form in: * Reprinted in: See also *Nasonov pheromone The Nasonov (alternatively, Nasanov) pheromone is released by worker bees to ori ...

Nikolai Nasonov
Nikolai Viktorovich Nasonov (russian: Николай Викторович Насонов; 14 February 1855 – 11 February 1939) was a Russian zoologist. In 1879 he graduated from the Imperial Moscow University and became an assistant at its Zoological Museum. After defending his PhD in 1887 he lectured at his alma mater, and later worked in Trieste, Marseille and Warsaw. In 1890 he defended a habilitation on the evolution of anteaters. In December 1897 he was elected as a corresponding and in March 1906 as a full member of the Russian Academy of Sciences. In addition to his studies in zoology Nasonov also dealt with the race problem based on Marxism and published articles in '' Revolutsionnyi vostok'', a monthly journal published by the Communist University of the Toilers of the East The Communist University of the Toilers of the East (KUTV) (russian: link=no, Коммунистический университет трудящихся Востока; also known as the Far ...

Beehive (beekeeping)
A beehive is an enclosed structure in which some honey bee species of the subgenus '' Apis'' live and raise their young. Though the word ''beehive'' is commonly used to describe the nest of any bee colony, scientific and professional literature distinguishes ''nest'' from ''hive''. ''Nest'' is used to discuss colonies that house themselves in natural or artificial cavities or are hanging and exposed. ''Hive'' is used to describe an artificial/man-made structure to house a honey bee nest. Several species of ''Apis'' live in colonies, but for honey production the western honey bee (''Apis mellifera'') and the eastern honey bee (''Apis cerana'') are the main species kept in hives. The nest's internal structure is a densely packed group of hexagonal prismatic cells made of beeswax, called a honeycomb. The bees use the cells to store food (honey and pollen) and to house the brood (eggs, larvae, and pupae). Beehives serve several purposes: production of honey, pollination of near ...

Swarming (honey Bee)
Swarming is a honey bee colony's natural means of reproduction. In the process of swarming, a single colony splits into two or more distinct colonies. Swarming is mainly a spring phenomenon, usually within a two- or three-week period depending on the locale, but occasional swarms can happen throughout the producing season. Secondary ''afterswarms'', or ''cast swarms'' may happen. Cast swarms are usually smaller and are accompanied by a virgin queen. Sometimes a beehive will swarm in succession until it is almost totally depleted of workers. One species of honey bee that participates in such swarming behavior is ''Apis cerana.'' The reproduction swarms of this species settle away from the natal nest for a few days and will then depart for a new nest site after getting information from scout bees. Scout bees search for suitable cavities in which to construct the swarm's home. Successful scouts will then come back and report the location of suitable nesting sites to the other bees. ...

Pheromone (honeybee)
The pheromones of the honey bee are mixtures of chemical substances released by individual bees into the hive or environment that cause changes in the physiology and behaviour of other bees. Introduction Honey bees (''Apis mellifera'') have one of the most complex pheromonal communication systems found in nature, possessing 15 known glands that produce an array of compounds.Free, John B., ''Pheromones of social bees.'' Ithaca, N.Y.: Comstock, 1987.Blum, M.S. 1992. Honey bee pheromones in The Hive and the Honey Bee, revised edition (Dadant and Sons: Hamilton, Illinois), pages 385–389. These chemical messengers secreted by a queen, drone, worker bee or laying worker bee to elicit a response in other bees. The chemical messages are received by the bee's antenna and other body parts. They are produced as a volatile or non-volatile liquid and transmitted by direct contact as a liquid or vapor. Honey bee pheromones can be grouped into releaser pheromones which temporarily affect the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citral
Citral is an acyclic monoterpene aldehyde, and being a monoterpene, it is made of two isoprene units. Citral is a collective term which covers two geometric isomers that have their own separate names; the ''E''-isomer is named geranial (''trans''-citral) or citral A. The ''Z''-isomer is named neral (''cis''-citral) or citral B. These stereoisomers occur as a mixture, not necessarily racemic; e.g. in essential oil of Australian ginger, the neral to geranial ratio is 0.61. Occurrence Citral is present in the oils of several plants, including lemon myrtle (90–98%), '' Litsea citrata'' (90%), ''Litsea cubeba'' (70–85%), lemongrass (65–85%), lemon tea-tree (70–80%), ''Ocimum gratissimum'' (66.5%), '' Lindera citriodora'' (about 65%), '' Calypranthes parriculata'' (about 62%), petitgrain (36%), lemon verbena (30–35%), lemon ironbark (26%), lemon balm (11%), lime (6–9%), lemon (2–5%), and orange. Further, in the lipid fraction (essential oil) of Australian ginger (51- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Nerolic Acid
Nerolic acid, also known as (''Z'')-3,7-Dimethyl-2,6-octadienoic acid, is an organically-derived chemical. In nature Nerolic acid is found in the Nasonov scent gland of honey-bees along with geraniol, geranic acid, citral, farnesol, and nerol. Of these, nerolic acid, geraniol, and farnesol are present in the highest proportions.. It is one of the five compounds that are part of the essential oils of ''Myrcia Ovata''. It is a compound also found in great quantity in ''Myrcia lundiana'' and it possess antifungal properties against pathogens such as ''Fusarium solani,'' and ''Lasiodiplodia theobromae''. Both ''Myrcia Ovata'' and ''Myrcia lundiana'' are part of the Myrtaceae family plant, both containing a certain percentage of Nerolic acid compound. In addition to this, Nerolic acid is also a principal chemical compound of essential oils of lemongrass ''Cymbopogon'', also known as lemongrass, barbed wire grass, silky heads, Cochin grass, Malabar grass, oily heads, cit ...
