Gasterophilus
''Gasterophilus'', commonly known as botfly, is a genus of parasitic fly from the family Oestridae that affects different types of animals, especially horses, but it can also act on cows, sheep, and goats. A case has also been recorded in a human baby. This parasite affects the animal gastrointestinal tract in order to give to their offspring an alimentary source. Although not deadly, due to the usual low larva population that infests the animal, large larva populations can cause health issues to the host. For example, a typical horse can tolerate a hundred larvae without any effects. Species There are nine species of Gasterophilus: *'' Gasterophilus flavipes'' – ranges Palaearctic and Afrotropical, primarily infects donkeys *'' Gasterophilus haemorrhoidalis'' (lip botfly) – ranges worldwide and primarily infects horses, mules, donkey and reindeer *'' Gasterophilus inermis'' – an Old World species that infects horses, donkeys and zebra *'' Gasterophilus intestinalis'' ...

Gasterophilus Pecorum
''Gasterophilus pecorum'' is a species of botfly within the genus '' Gasterophilus'' that is an obligate parasite of horses and other equids. ''Gasterophilus pecorum'' is found in the desert steppe of Xinjiang, China, where it is the most prevalent botfly species. In Kalamaili Nature Reserve (KNR), China, ''G. pecorum'' is a major problem for the health of Przewalski's horse, which has been reintroduced in the area. ''Gasterophilus pecorum'' has also been observed infecting equids, such as the Persian Onager ('' Equus hemionus onager).'' Of the six identified species of '' Gasterophilus'' found within the KNR'','' ''G. pecorum'' is responsible for a majority of all botfly infections. Taxonomy Larvae ''G. pecorum'' larvae have several larval instars, these larvae move throughout their host's digestive tract while going through these life stages. Similar to other members of the genus '' Gasterophilus,'' in their last larval stage ''G. pecorum'' have a set of hooked mouth parts ...

Gasterophilus Nasalis
''Gasterophilus nasalis'' (also called throat bot fly or horse nasal bot fly) is a species of the genus ''Gasterophilus'' and family Oestridae. This species is found worldwide, but prominently present within the summer months. This species of ''G. nasalis'' primarily targets equines, such as horses, donkeys and the plains zebra. However, it's known that it targets cattle as well, along with mild cases of companion animals. Occurrence Besides the Gasterophilus intestinalis, the Gasterophilus Nasalis is the most common horse bottle fly. In a research paper from 1951 to 1973, 80.6% of horses examined in Kentucky were hosts of the Gasterophilus nasalis in the second or third instar. In Morocco, they occurred together with the G. intestinalis. While third instar larvae were present during the whole year, larvae in the second instar were only present in April. Young horses were more likely to be infected with the parasite. Life cycle Horse bottle flies lay their eggs typically aroun ...

Gasterophilus Intestinalis
''Gasterophilus intestinalis'', also known as horse bot fly, is a species of insect of the family Oestridae, and is found worldwide. The adults, which have a bumblebee-like appearance, are prominently active in the summer. ''G. intestinalis'' is primarily a parasite of horses, mules and donkeys. Identification The eggs of ''G. intestinalis'' are pale yellow in color, and long. The larvae are yellow or tan. Adults, which are long, look superficially like hairy bumblebees, with a noticeable ovipositor at the end of the abdomen. Life cycle The female fly cements individual eggs onto hairs of the forelimbs and shoulders of horses, mules and donkeys. Each female lays up to 1000 eggs. In order to hatch, the eggs must be licked by the host animal. If taken into the host's mouth during grooming, the egg will hatch in the mouth. If not, the first instar larva will migrate to the mouth. The larvae develop in the tissue the tongue, in tunnels within of the surface. Second instar larva ...

Gasterophilus Haemorrhoidalis
''Gasterophilus haemorrhoidalis'' (also called nose botfly or lip botfly) is a species of the genus ''Gasterophilus'' that lays eggs on the lips and around the mouth of horses, mules and donkeys. In Equidae, third-stage larvae attach to the stomach, but also to the rectum, sometimes in great numbers.Johannes Kaufmann, Parasitic Infections of Domestic Animals, Birkhäuser Verlag, Basel, Boston, Berlin, 1996, . Heavy infestation can cause anal prolapse in foals and mules. They do not parasitise humans.

Oestridae
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 warble ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles De Geer
Baron Charles de Geer (the family is usually known as De Geer with a capitalized "De" and is pronounced "de yer"); Finspång in Risinge 30 January 1720 – Stockholm 7 March 1778) was a Swedish industrialist and entomologist. Life De Geer, who came from a family with strong Dutch connections, grew up in Utrecht from the age of three. He returned to Sweden at the age of 19. He had inherited the entailed manor and important iron-works of Leufsta (Lövsta) in Uppland from his childless uncle and namesake and would substantially increased the wealth of the estate. Ever since he had received a present of some silk worms at the age of eight, he had an interest in entomology and became a respected amateur entomologist at an early age. His major work was the ''Mémoires pour servir à l'histoire des insectes'' (eight volumes, 1752-1778). He was elected a member of the Royal Swedish Academy of Sciences already in 1739, at the age of nineteen, and a corresponding member of the Fren ...
