Botfly
Botflies, also known as warble flies, heel flies, and gadflies, are a family of flies known as the Oestridae. Their larvae are internal parasites of mammals, some species growing in the host's flesh and others within the gut. '' Dermatobia hominis'' is the only species of botfly known to parasitize humans routinely, though other species of flies cause myiasis in humans. General A botfly, also written bot fly, bott fly or bot-fly in various combinations, is any fly in the family Oestridae. Their life cycles vary greatly according to species, but the larvae of all species are internal parasites of mammals. Largely according to species, they also are known variously as warble flies, heel flies, and gadflies. The larvae of some species grow in the flesh of their hosts, while others grow within the hosts' alimentary tracts. The word "bot" in this sense means a maggot. A warble is a skin lump or callus such as might be caused by an ill-fitting harness, or by the presence of a war ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myiasis
Myiasis is the parasitic infestation of the body of a live animal by fly larvae (maggots) which grow inside the host while feeding on its tissue. Although flies are most commonly attracted to open wounds and urine- or feces-soaked fur, some species (including the most common myiatic flies—the botfly, blowfly, and screwfly) can create an infestation even on unbroken skin and have been known to use moist soil and non-myiatic flies (such as the common housefly) as vector agents for their parasitic larvae. Because some animals (particularly non-native domestic animals) cannot react as effectively as humans to the causes and effects of myiasis, such infestations present a severe and continuing problem for livestock industries worldwide, causing severe economic losses where they are not mitigated by human action. Although typically a far greater issue for animals, myiasis is also a relatively frequent disease for humans in rural tropical regions where myiatic flies thrive, and ...

Dermatobia Hominis
The human botfly, ''Dermatobia hominis'' (Greek δέρμα, skin + βίος, life, and Latin '' hominis'', of a human), is a species of botfly whose larvae parasitise humans (in addition to a wide range of other animals, including other primates). It is also known as the torsalo or American warble fly, though the warble fly is in the genus ''Hypoderma'' and not ''Dermatobia'', and is a parasite on cattle and deer instead of humans. ''Dermatobia'' fly eggs have been shown to be vectored by over 40 species of mosquitoes and muscoid flies, as well as one species of tick; the female captures the mosquito and attaches its eggs to its body, then releases it. Either the eggs hatch while the mosquito is feeding and the larvae use the mosquito bite area as the entry point, or the eggs simply drop off the muscoid fly when it lands on the skin. The larvae develop inside the subcutaneous layers, and after about eight weeks, they drop out to pupate for at least a week, typically in the so ...

Cephenemyia Stimulator
The name deer botfly (also deer nose botfly) refers to any species in the genus ''Cephenemyia'' (sometimes misspelled as ''Cephenomyia'' or ''Cephenemya''), within the family Oestridae. They are large, gray-brown flies, often very accurate mimics of bumblebees. They attack chiefly the nostrils and pharyngeal cavity of members of the deer family. The larva of ''Cephenemyia auribarbis'', infesting the stag, is called a stagworm. The genus name comes from the Greek ''kēphēn'', drone bee, and ''myia'', fly. Description The larval stages of ''Cephenemyia'' are obligate parasites of cervids. Eggs hatch in the uterus of the female. She then flies close to the head of her host species and while hovering ejects her larvae into its nostrils. Larvae migrate to the base of the animal's tongue, where they mature in clusters to a size of 25 to 36 mm. After being ejected by the host, they pupate in soil (2 to 3 weeks) before emerging as a sexually-mature but non-feeding adult, which must ...

Ecuadorian Mantled Howler (Alouatta Palliata Aequatorialis) Juvenile Male With Botfly (Oestridae Sp
The Ecuadorian mantled howler (''Alouatta palliata aequatorialis'') is a subspecies of the mantled howler, ''A. palliata''. It ranges from Panama (or possibly the eastern tip of Costa Rica) through Colombia and Ecuador into northern Peru. The range limits between the Ecuadorian mantled howler and the golden-mantled howler The golden-mantled howler (''Alouatta palliata palliata'') is a subspecies of the mantled howler, ''A. palliata''. It ranges throughout much of Central America, in Guatemala, Honduras, Nicaragua and Costa Rica, and possibly Panama. The range ... are not entirely clear. The Ecuadorian mantled howler replaces the Golden-mantled howler in either extreme eastern Costa Rica or western Panama. The Ecuadorian mantled howler differs from the golden-mantled howler primarily by being paler, with a more yellowish mantle.

Oestrinae
Oestrinae is a subfamily of Oestridae which includes parasitic flies attacking a range of different hosts. There are 9 genera with 34 species in this subfamily, which typically spend their larval stage in the skin or soft tissues of mammals, including deer or sheep Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated sh ... (such species are often considered pests). The adult flies give birth to living larva in the host's nostril. References * Pape, T. (2001). Phylogeny of Oestridae (Insecta: Diptera).

Flies
Flies are insects of the Order (biology), order Diptera, the name being derived from the Ancient Greek, Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing an estimated 1,000,000 species including horse-fly, horse-flies, crane fly, crane flies, hoverfly, hoverflies and others, although only about 125,000 species have Species description, been described. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great maneuverability in flight, and claws and pads on their feet enable them to cling to smooth ...

Skin
Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation. Other cuticle, animal coverings, such as the arthropod exoskeleton, have different cellular differentiation, developmental origin, structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin ''cutis'' 'skin'). In mammals, the skin is an organ (anatomy), organ of the integumentary system made up of multiple layers of ectodermal tissue (biology), tissue and guards the underlying muscles, bones, ligaments, and internal organs. Skin of a different nature exists in amphibians, reptiles, and birds. Skin (including cutaneous and subcutaneous tissues) plays crucial roles in formation, structure, and function of extraskeletal apparatus such as horns of bovids (e.g., cattle) and rhinos, cervids' antlers, giraffids' ossicones, armadillos' osteoderm, and os penis/os clitoris. All mammals have som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tick
Ticks (order Ixodida) are parasitic arachnids that are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, species, and "fullness". Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families, the Ixodidae or hard ticks, and the Argasidae, or soft ticks. '' Nuttalliella,'' a genus of tick from southern Africa is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks. Adults have ovoid/pear-shaped bodies (idiosomas) which become engorged with blood when they feed, and eight legs. Their cephalothorax and abdomen are completely fused. In ad ...

Digestive Tract
The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus. The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines. Food taken in through the mouth is digested to extract nutrients and absorb energy, and the waste expelled at the anus as feces. ''Gastrointestinal'' is an adjective meaning of or pertaining to the stomach and intestines. Most animals have a "through-gut" or complete digestive tract. Exceptions are more primitive ones: sponges have small pores (ostia) throughout their body for digestion and a larger dorsal pore ( osculum) for excretion, comb jellies have both a ventral mouth and dorsal anal pores, while cnidarians and acoels have a single pore for both digestion and excretion. The human gastrointestinal tract consists of the esophagus, stomach, and intestines, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhinophoridae
Rhinophoridae is a family of flies (Diptera), commonly known as Woodlouse Flies, found in all zoogeographic regions except Oceania, but mainly in the Palaearctic and Afrotropical regions. They are small, slender, black, bristly flies phylogenetically close to the Tachinidae, although some authors consider them a sister group of the Calliphoridae. The larvae are mostly parasitoids of woodlice, beetles, spiders, and other arthropods, and occasionally snails. By 2020, about 33 genera were placed in the family, with a total 177 species. Genera include: *'' Acompomintho'' Villeneuve, 1927 *'' Apomorphyto'' Cerretti, Lo Giudice & Pape, 2014 *'' Aporeomyia'' Pape & Shima, 1993 *'' Axinia'' Colless, 1994 *'' Azaisia'' Villeneuve, 1939 *'' Baniassa'' Kugler, 1978 *'' Bezzimyia'' Townsend, 1919 *'' Bixinia'' Cerretti, Lo Giudice & Pape, 2014 *'' Comoromyia'' Crosskey, 1977 *'' Kinabalumyia'' Cerretti & Pape, 2020 *'' Macrotarsina'' Schiner, 1857 *'' Malayia'' Malloch, 1926 *'' Marsha ...

Housefly
The housefly (''Musca domestica'') is a fly of the suborder Cyclorrhapha. It is believed to have evolved in the Cenozoic Era, possibly in the Middle East, and has spread all over the world as a commensal of humans. It is the most common fly species found in houses. Adults are gray to black, with four dark, longitudinal lines on the thorax, slightly hairy bodies, and a single pair of membranous wings. They have red eyes, set farther apart in the slightly larger female. The female housefly usually mates only once and stores the sperm for later use. She lays batches of about 100 eggs on decaying organic matter such as food waste, carrion, or feces. These soon hatch into legless white larvae, known as maggots. After two to five days of development, these metamorphose into reddish-brown pupae, about long. Adult flies normally live for two to four weeks, but can hibernate during the winter. The adults feed on a variety of liquid or semi-liquid substances, as well as solid m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
