| '''Ethnoentomology''' is the study of the relationship between ]s and people. The name is derived from "]" - study of people and "]" - study of insects. The focus of ethnoentomology is on how insects have been or are being used in human societies around the world. This includes insects used for food, rituals and medicine. As with in entomology, the term is sometimes used more broadly to encompass ]s more broadly. | |||
| ==Insects as food== | |||
| {{main|Entomophagy}} | |||
| ] refers to the eating of insects. Many insects are considered a culinary ] in many parts of the world, but the practice is uncommon and even taboo in other societies. Insects used in food include ], ], ]s, ]s & other beetle and moth larvae; crickets, ] & locusts; and arachnids, such as ]s & ]s. They can be eaten on their own or mixed with other ingredients, such is the case with ]. | |||
| ==Insects in medicine== | |||
| {{main|Insects in medicine}} | |||
| ===Traditional and Alternative Use of Insects in Medicine=== | |||
| The medicinal uses of insects were often defined by the ], which stated that an organism bearing parts that resemble human body parts, animals, or other objects, was thought to have useful relevance to those parts, animals or objects. So, for example, the femurs of grasshoppers, which were said to resemble the human liver, were used to treat liver ailments by the indigenous peoples of Mexico.<ref name="Mexico">Ramos-Elorduy de Concini, J. and J.M. Pino Moreno. (1988). The utilization of insects in the empirical medicine of ancient Mexicans. ''Journal of Ethnobiology, 8(2), 195-202.''</ref> This doctrine is common throughout traditional and alternative medicine, but is most prominent where medical traditions are broadly accepted, as in ] and ], and less by community and family based medicine, as is more common in parts of Africa. | |||
| ====Traditional Chinese Medicine==== | |||
| {{further|Traditional Chinese Medicine}} | |||
| Traditional Chinese Medicine often makes use of insects as part of its herbal medicine component, and their medical properties and applications are broadly accepted and agreed upon. For example, ] is used to treat tetanus, seizures, and convulsions.<ref name="centipede">http://tcm.health-info.org/Herbology.Materia.Medica/wugong-properties.htm</ref> The Chinese Black Mountain Ant, ''] Vicina'', is used as a cure all, especially by the elderly. It is said to prolong life, to have anti-aging properties, to replenish ], and to increase virility and fertility. Recent interest in the ants' medicinal qualities by British researchers has led to investigations into the extract's ability to serve as a cancer-fighting agent.<ref name="BBC">http://news.bbc.co.uk/2/hi/health/1809450.stm</ref> | |||
| ====India and Ayurveda==== | |||
| {{further|Ayurveda}} | |||
| Ayurveda is a traditional treatment used alongside Western medicine in India. Although it is often effective, doses are often inconsistent and contaminated with toxic heavy metals.<ref name="Nyishi">Chakravorty, J., Ghosh, S., and V.B. Meyer-Rochow. (2011). Practices of entomophagy and entomotherapy by members of the Nyishi and Galo tribes, two ethnic groups of the state of Arunachal Pradesh (North-East India). ''Journal of Ethnobiology and Ethnomedicine 7(5)''</ref> ] (insects plus mound) is said to cure a variety of diseases, both specific and vague,<ref name="Bioprospecting">Srivastava, S.K., Babu, N., and H. Pandey. (2009). Traditional insect bioprospecting--As human food and medicine. ''Indian Journal of Traditional Knowledge, 8(4):'' 485-494.</ref> including ulcers, rheumatic diseases, anaemia, and pain; and to improve health generally.<ref name="Nyishi" /> | |||
| The Jatropha Leaf Miner is a major insect agricultural pest which is also a medicinal remedy.<ref name="Bioprospecting" /> The larvae are used boiled to induce lactation, reduce fever, and soothe the gastrointestinal tract.<ref name="Bioprospecting" /> | |||
| ====Africa==== | |||
| The traditional insect medicine of Africa is varied and local, rather than formalised like Ayurveda.<ref name="Bioprospecting" /> ] is used as food, and as medicine for headaches.<ref name="Bioprospecting" /> ] is applied to wounds to prevent infection, or consumed to treat internal hemorrhages.<ref name="Bioprospecting" /> Termites are also used as a medical device to insert a medicine that has been spread on the skin subcutaneously.<ref name="Bioprospecting" /> | |||
| ====Americas==== | |||
| The Americas were influenced by the Doctrine of Signatures, most likely because of their colonial history with Europe. The majority of insect use in medicine is associated with Central America and parts of South America, rather than North America, and most of it is based on the medical techniques of indigenous peoples.<ref name="Mexico" /> Insect medicine is practiced much more rarely than in China, India, or Africa, though it is still relatively common in rural areas with large indigenous populations.<ref name="Mexico" /> Grasshoppers, known as ], are eaten in Mexico, and used as a diuretic to treat kidney diseases, to reduce swelling, and to relieve the pain of intestinal disorders.<ref name="Mexico" /> Ants were sometimes used as medicinal devices by the indigenous peoples of Central America.<ref name="Mexico" /> The soldier caste of the ] were used as living sutures by Mayans.<ref name="Mexico" /> The salivary gland secretions of the ant were used to treat infections.<ref name="Mexico" /> The venom of the ] was used to cure rheumatism, arthritis, and polimyelitis via the immunological reaction produced by its sting.<ref name="Mexico" /> | |||
| The silkworm, '']'', was used for food and as a medicine in Central America after it was brought to the New World.<ref name="Mexico" /> Boiled pupae were taken to treat apoplexy, aphasy, bronchitis, pneumonia, convulsions, hemorrhages, and frequent urination.<ref name="Mexico" /> The excrement produced by the larvae is also eaten to improve circulation and to alleviate the symptoms of cholera.<ref name="Mexico" /> | |||
| ====Honey bee products==== | |||
| ] products are used medicinally across Asia, Europe, Africa, Australia, and the Americas, despite the fact that the honey bee was not introduced to the Americas until the colonization by Spain and Portugal. They are by far the most common medical insect product both historically and currently.<ref name="Bioprospecting" /> | |||
| ] is the most frequently referenced medical bee material. It can be applied to skin to treat excessive scar tissue, rashes, and burns,<ref name="China">Feng, Y., Zhao, M., He, Z., Chen, Z., and L. Sun. (2009). Research and utilization of medicinal insects in China. ''Entomological Research, 39:'' 313-316.</ref> and can be applied as a poultice to eyes to treat infection.<ref name="Nyishi" /> It is also consumed for digestive problems and as a general health restorative, and can be heated and consumed to treat head colds, cough, throat infections, laryngitis, tuberculosis, and lung diseases.<ref name="Mexico" /> | |||
| Additionally, ], or honey bee venom, can be applied via direct stings to relieve arthritis, rheumatism, polyneuritis, and asthma.<ref name="Mexico" /> ], a resinous, waxy mixture collected by honeybees and used as a hive insulator and sealant, is often consumed by menopausal women because of its high hormone content, and it is said to have antibiotic, anesthetic, and anti-inflammatory properties.<ref name="Mexico" /> ] is used to treat anemia, gastrointestinal ulcers, arteriosclerosis, hypo- and hypertension, and inhibition of sexual libido.<ref name="Mexico" /> Finally ], or bee pollen, is eaten as a generally health restorative, and is said to help treat both internal and external infections.<ref name="Mexico" /> All of these honey bee products are regularly produced and sold, especially online and in health food stores, though none are yet approved by the FDA. | |||
| ===Modern Scientific Use of Insects in Medicine=== | |||
| Though insects were widely used throughout history for medical treatment on nearly every continent, relatively little medical entomological research has been conducted since the revolutionary advent of antibiotics. Heavy reliance on antibiotics, coupled with discomfort with insects in Western culture limited the field of insect ] until the rise of antibiotic resistant infections sparked pharmaceutical research to explore new resources. Arthropods represent a rich and largely unexplored source of new medicinal compounds.<ref>Dossey, A.T., 2010. Insects and their chemical weaponry: new potential for drug discovery. Nat. Prod. Rep 27, 1737e1757.</ref> | |||
| ====Maggot therapy==== | |||
| One of the most commonly used insects in medical purposes is the blow fly larvae. The first recorded use of it was during World War II. Military surgeons noticed that wounds which were left untreated for several days and which became infested with maggots, healed better than wounds not infested with the blow fly larvae. It was later discovered that the larvae secreted a chemical called ], which had a curative effect. Allantoin is now being used to treat the infectious bone disease, ]. | |||
| ] is the intentional introduction of live, disinfected fly larvae into non-healing or dead skin and soft tissue wounds of a human or other animal for the purpose of selectively cleaning out only the ] tissue within a wound in order to promote wound healing. It is also used to prevent infection and to speed the healing process. | |||
| ====Apitherapy==== | |||
| ] is the medical use of honeybee products such as honey, pollen, bee bread, propolis, royal jelly and bee venom. One of the major ]s in bee venom, called ], has the potential to treat inflammation in sufferers of ] and ]. Melittin blocks the expression of inflammatory genes, thus reducing swelling and pain. It is administered by direct insect sting, or intramuscular injections. Bee products demonstrate a wide array of antimicrobial factors and in laboratory studies and have been shown to kill antibiotic resistant bacteria, pancreatic cancer cells, and many other infectious microbes.<ref name="N.A. Ratcliffe 2011">N.A. Ratcliffe et al. Insect Biochemistry and Molecular Biology 41 (2011) 747e769</ref> | |||
| ====Blister Beetle and Spanish Fly==== | |||
| ], the blister-causing oil found in several families of beetles, was accepted by the ] in 2004 as treatment for warts and other skin problems. It also has historical use by the Greeks and Romans and is used as an ] in some societies. Recent studies in cell culture and animal models have demonstrated powerful tumor fighting properties of Cantharidin.<ref name="N.A. Ratcliffe 2011"/> | |||
| ====Blood-Feeding Insects==== | |||
| Many blood-feeding insects like ticks, horseflies, and mosquitoes inject multiple bioactive compounds into their prey. These insects have been used by practitioners of Eastern Medicine for hundreds of years to prevent blood clot formation or thrombosis.<ref>Yang, X., Hu, K., Yan, G., et al., 2000. Fibrinogenolytic components in Tabanid, an ingredient in traditional Chinese medicine and their properties. J. Southwest Agric. Univ. 22, 173e176 (Chinese).</ref> However, modern medical research has only recently begun to investigate the drug development potential of blood-feeding insect saliva. These compounds in the saliva of blood feeding insects are capable of increasing the ease of blood feeding by preventing coagulation of platelets around the wound and provide protection against the host’s immune response. Currently, over 1280 different protein families have been associated with the saliva of blood feeding organisms.<ref>Ribeiro, J.M.C., Arca, B., 2009. From sialomes to the sialoverse: an insight into salivary potion of blood-feeding insects. Adv. Insect Physiol. 37, 59e118.</ref> This diverse range of compounds may include:<ref name="N.A.

| Currently, some preliminary progress has been made with investigation of the therapeutic properties of tick anticoagulant peptide (TAP) and Ixolaris a novel recombinant ] (TFPI) from the salivary gland of the tick, '']''.<ref>Maritz-Olivier, C., Stutzer, C., Jongejan, F., et al., 2007. Tick anti-hemostatics: targets for future vaccines and therapeutics. Trends Parasitol. 23, 397e407.</ref> Additionally, Ixolaris, a ] inhibitor has been shown to block primary tumor growth and angiogenesis in a glioblastoma model.<ref>Carneiro-Lobo, T.C., Konig, S., Machado, D.E., 2009. Ixolaris, a tissue factor inhibitor, blocks primary tumor growth and angiogenesis in a glioblastoma model. J. Thromb. Haemost. 7, 1855e1864.</ref> Despite the strong potential of these compounds for use as anticoagulants or immunomodulating drugs no modern medicines, developed from the saliva of blood-sucking insects, are currently on the market.<ref name="N.A. Ratcliffe 2011"/> | |||
| ===Arachnids in Modern Medicine=== | |||
| Like plants and insects, arachnids have also been used for thousands of years in traditional medical practices. Recent scientific research in natural bioactive factors has increased, leading to a renewed interest in venom components in many animals. In 1993 ] was synthesized from the venom of the ''] margaritatus'' the Central American bark scorpion. It is a peptide that selectively inhibits ]. Patented by Merck, it has the potential to prevent ], a common cause of bypass graft failure.<ref>E. M. Costa-Neto, An. Acad. Bras. Cienc., 2005, 77(1), 33–43.</ref> | |||
| A great amount of research has recently been directed toward the synthesis and use of ] as a scaffolding for ligament generation. Spider silk is an ideal material for the synthesis of medical skin grafts or ligament implants because it is one of the strongest known natural fibers and triggers little immune response in animals. Spider silk may also be used to make fine sutures for stitching nerves or eyes to heal with little scarring. Medical uses of spider silk is not a new idea. Spider silks have been used for thousands of years to fight infection and heal wounds. Efforts to produce industrial quantities and qualities of spider silk in transgenic goat milk are underway.<ref>http://www.livescience.com/15443-artificial-skin-spun-spider-silk.html</ref><ref>Vendrely, C. and Scheibel, T. (2007), Biotechnological Production of Spider-Silk Proteins Enables New Applications. Macromolecular Bioscience, 7: 401–409. {{doi|10.1002/mabi.200600255}}</ref> | |||
| ====Psychoactive Scorpions==== | |||
| Recent news reports<ref>http://www.wired.com/culture/lifestyle/news/2001/11/48310</ref> claim that use of scorpions for psychoactive purposes is gaining in popularity in Asia. Heroin addicts in Afghanistan are purported to smoke dried scorpions or use scorpion stings to get high when heroin is not available. The ‘scorpion sting craze’ has also increased in India with a decreasing availability of other drugs and alcohol available to youth.<ref>http://www.treatmentsolutionsnetwork.com/blog/index.php/2011/04/08/uses-for-scorpion-venom/</ref> Young people are reportedly flocking to highway sides where they can purchase scorpion stings that after several minutes of intense pain, supposedly produce a six- to eight-hour feeling of wellbeing.<ref>"Drugs in Afghanistan: opium, outlaws and scorpion tales." David Macdonald. Pluto. 2007</ref> | |||
| ==Insects in Religious Practices== | |||
| {{main|Insects in religion}} | |||
| In the Brazilian ], members of the ] language family have been observed using ''Pachycondyla commutata'' ants during female rite-of-passage ceremonies, and prescribing the sting of ''Pseudomyrmex'' spp. for fevers and headaches.<ref>] (2000), "Antiquity of Traditional Ethnobiological Knowledge in Amazonia: a Tupí–Guaraní Family and Time" ''Ethnohistory'' 47(2):399-422.</ref> | |||
| ], a red harvester ant, has been widely used by natives of Southern California and Northern Mexico for hundreds of years in ceremonies conducted to help tribe members acquire spirit helpers through hallucination. During the ritual, young men are sent away from the tribe and consume large quantities of live, unmasticated ants under the supervision of an elderly member of the tribe. Ingestion of ants should lead to a prolonged state of unconsciousness where dream helpers appear and serve as allies to the dreamer for the rest of his life.<ref>Kevin Groark.
