Apamin is an 18 amino acid globular peptide neurotoxin found in apitoxin (bee venom). Dry bee venom consists of 2–3% of apamin. Apamin selectively blocks SK channels, a type of Ca2+-activated K+ channel expressed in the central nervous system. Toxicity is caused by only a few amino acids, these are cysteine1, lysine4, arginine13, arginine14 and histidine18. These amino acids are involved in the binding of apamin to the Ca2+-activated K+ channel. Due to its specificity for SK channels, apamin is used as a drug in biomedical research to study the electrical properties of SK channels and their role in the afterhyperpolarizations occurring immediately following an action potential.Apitherapy
Apitherapy is a branch of alternative medicine that uses honey bee products, including honey, pollen, propolis, royal jelly and bee venom. Proponents of apitherapy make claims for its health benefits which are unsupported by evidence-based medicine.Bee
Bees are flying insects closely related to wasps and ants, known for their role in pollination and, in the case of the best-known bee species, the western honey bee, for producing honey and beeswax. Bees are a monophyletic lineage within the superfamily Apoidea and are presently considered a clade, called Anthophila. There are over 16,000 known species of bees in seven recognized biological families. They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants.
Some species including honey bees, bumblebees, and stingless bees live socially in colonies. Bees are adapted for feeding on nectar and pollen, the former primarily as an energy source and the latter primarily for protein and other nutrients. Most pollen is used as food for larvae. Bee pollination is important both ecologically and commercially. The decline in wild bees has increased the value of pollination by commercially managed hives of honey bees.
Bees range in size from tiny stingless bee species whose workers are less than 2 millimetres (0.08 in) long, to Megachile pluto, the largest species of leafcutter bee, whose females can attain a length of 39 millimetres (1.54 in). 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. Vertebrate predators of bees include birds such as bee-eaters; insect predators include beewolves and dragonflies.
Human beekeeping or apiculture has been practised for millennia, since at least the times of Ancient Egypt and Ancient Greece. Apart from honey and pollination, honey bees produce beeswax, royal jelly and propolis. Bees have appeared in mythology and folklore, through all phases of art and literature, from ancient times to the present day, though primarily focused in the Northern Hemisphere, where beekeeping is far more common.
The analysis of 353 wild bee and hoverfly species across Britain from 1980 to 2013 found the insects have been lost from a quarter of the places they inhabited in 1980.Bee sting
A bee sting is a sting from a bee (honey bee, bumblebee, sweat bee, etc.). The stings of most of these species can be quite painful, and are therefore keenly avoided by many people.
Bee stings differ from insect bites, and the venom or toxin of stinging insects is quite different. Therefore, the body's reaction to a bee sting may differ significantly from one species to another. In particular, bee stings are acidic, whereas wasp stings are alkaline, so the body's reaction to a bee sting may be very different from that of a wasp sting.The most aggressive stinging insects are vespid wasps (including bald-faced hornets and other yellowjackets) and hornets (especially the Asian giant hornet). All of these insects aggressively defend their nests.
Although for most people a bee sting is painful but otherwise relatively harmless, in people with insect sting allergy, stings may trigger a dangerous anaphylactic reaction that is potentially deadly. Additionally, honey bee stings release pheromones that prompt other nearby bees to attack.Bug-Eyed Bandit
Bug-Eyed Bandit is the name of two fictional supervillains appearing in American comic books published by DC Comics.
A female version of the Bug-Eyed Bandit appears in the Arrowverse shows The Flash and Arrow, played by Emily Kinney.Flea circus
A flea circus is a circus sideshow attraction in which fleas are attached (or appear to be attached) to miniature carts and other items, and encouraged to perform circus acts within a small housing.Hive management
Hive management in beekeeping refers to intervention techniques that a beekeeper may perform to ensure hive survival and to maximize hive production. Hive management techniques vary widely depending on the objectives.Honey bee
A honey bee (also spelled honeybee) is a eusocial flying insect within the genus Apis of the bee clade. They are known for construction of perennial, colonial nests from wax, for the large size of their colonies, and for their surplus production and storage of honey, distinguishing their hives as a prized foraging target of many animals, including honey badgers, bears and human hunter-gatherers. In the early 21st century, only seven species of honey bee are recognized, with a total of 44 subspecies, though historically seven to eleven species are recognized. The best known honey bee is the western honey bee which has been domesticated for honey production and crop pollination; modern humans also value the wax for candlemaking, soapmaking, lip balms, and other crafts. Honey bees represent only a small fraction of the roughly 20,000 known species of bees. Some other types of related bees produce and store honey and have been kept by humans for that purpose, including the stingless honey bees, but only members of the genus Apis are true honey bees. The study of bees, which includes the study of honey bees, is known as melittology.Human interactions with insects
Human interactions with insects include both a wide variety of uses, whether practical such as for food, textiles, and dyestuffs, or symbolic, as in art, music, and literature, and negative interactions including serious damage to crops and extensive efforts to eliminate insect pests.
Academically, the interaction of insects and society has been treated in part as cultural entomology, dealing mostly with "advanced" societies, and in part as ethnoentomology, dealing mostly with "primitive" societies, though the distinction is weak and not based on theory. Both academic disciplines explore the parallels, connections and influence of insects on human populations, and vice versa. They are rooted in anthropology and natural history, as well as entomology, the study of insects. Other cultural uses of insects, such as biomimicry, do not necessarily lie within these academic disciplines.
More generally, people make a wide range of uses of insects, both practical and symbolic. On the other hand, attitudes to insects are often negative, and extensive efforts are made to kill them. The widespread use of insecticides has failed to exterminate any insect pest, but has caused resistance to commonly-used chemicals in a thousand insect species.
Practical uses include as food, in medicine, for the valuable textile silk, for dyestuffs such as carmine, in science, where the fruit fly is an important model organism in genetics, and in warfare, where insects were successfully used in the Second World War to spread disease in enemy populations. One insect, the honey bee, provides honey, pollen, royal jelly, propolis and an anti-inflammatory peptide, melittin; its larvae too are eaten in some societies. Medical uses of insects include maggot therapy for wound debridement. Over a thousand protein families have been identified in the saliva of blood-feeding insects; these may provide useful drugs such as anticoagulants, vasodilators, antihistamines and anaesthetics.
Symbolic uses include roles in art, in music (with many songs featuring insects), in film, in literature, in religion, and in mythology. Insect costumes are used in theatrical productions and worn for parties and carnivals.Insects in medicine
Insects have long been used in medicine, both traditional and modern, sometimes with little evidence of their effectiveness. For the purpose of the article, and in line with custom, medicinal uses of other arthropods such as spiders are included.Moth
Moths comprise a group of insects related to butterflies, belonging to the order Lepidoptera. Most lepidopterans are moths, and there are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species.Queen Bee (comics)
Queen Bee is the name of six different DC Comics supervillains.Tertiapin
Tertiapin is a 21-amino acid peptide isolated from venom of the European honey bee (Apis mellifera). It blocks two different types of potassium channels, inward rectifier potassium channels (Kir) and calcium activated large conductance potassium channels (BK).This Is How You Die
This Is How You Die: Stories of the Inscrutable, Infallible, Inescapable Machine of Death is a 2013 collection of science fiction short stories, which is a follow up anthology to the Machine of Death, edited by Ryan North, Matthew Bennardo, and David Malki.Toxin
A toxin is a poisonous substance produced within living cells or organisms; synthetic toxicants created by artificial processes are thus excluded. The term was first used by organic chemist Ludwig Brieger (1849–1919), derived from the word toxic.Toxins can be small molecules, peptides, or proteins that are capable of causing disease on contact with or absorption by body tissues interacting with biological macromolecules such as enzymes or cellular receptors. Toxins vary greatly in their toxicity, ranging from usually minor (such as a bee sting) to almost immediately deadly (such as botulinum toxin).Venom
Venom is a secretion containing one or more toxins produced by an animal. Venom has evolved in a wide variety of animals, both predators and prey, and both vertebrates and invertebrates.
Venoms kill through the action of at least four major classes of toxin, namely necrotoxins and cytotoxins, which kill cells; neurotoxins, which affect nervous systems; and myotoxins, which damage muscles. Biologically, venom is distinguished from poison in that poisons are ingested, while venom is delivered in a bite, sting, or similar action. Venomous animals cause tens of thousands of human deaths per year. However, the toxins in many venoms have potential to treat a wide range of diseases.
