Culicoides Imicola
''Culicoides imicola'' (''Culicoides imicola'' Kieffer, former name ''C. pallidipennis'' Carter) is a species of Ceratopogonidae that transmits the bluetongue virus (BTV) and the African horse sickness virus.E. J. Wittmann, P. S. Mellor, and M. Baylis. “Using Climate Data to Map the Potential Distribution of Culicoides Imicola (Diptera: Ceratopogonidae) in Europe.” Revue Scientifique Et Technique De LOIE 20, no. 3 (January 2001): 731–40. https://doi.org/10.20506/rst.20.3.1306. This particular species has been recorded in Africa, Asia and Europe. African midges feed on animal blood, including horse, cattle, and sheep. Unlike other species within the ''Culicoides genus,'' this species prefers drier habitats for egg laying but retains a preference for moist soil to support larvae growth. Other suspected BTV vectors are ''Culicoides'' (''Culicoides'') ''pulicaris'' and species in the ''Culicoides'' (''Avaritia'') ''obsoletus'' complex. Description There are many species in the ...

Jean-Jacques Kieffer
Jean-Jacques Kieffer (1857 in Guinkirchen – 1925 in Bitche) was a French naturalist and entomologist who specialised in the study of parasitic insects. Educated as a priest, Kieffer taught natural science in Bitche, Lorraine while working on the description and classification of insects. His work and publications later became a predominant source of description and classification for entomologists in the early 20th century, in particular with regard to parasitoid wasps, midges, and mosquitos. He collaborated with the English entomologist Peter Cameron. Kieffer received an honorary Doctor honoris causa degree from the University of Strasbourg in 1904.

Topography
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically ''relief'', even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form (DEM). It is often considered to include the graphic representation of t ...

Orbivirus
''Orbivirus'' is a genus of double-stranded RNA viruses in the family ''Reoviridae'' and subfamily ''Sedoreovirinae''. Unlike other reoviruses, orbiviruses are arboviruses. They can infect and replicate within a wide range of arthropod and vertebrate hosts. Orbiviruses are named after their characteristic doughnut-shaped capsomers (''orbis'' in Latin means ring). Many orbiviruses are transmitted by ticks or haematophagus insect vectors (''Culicoides'', mosquitoes and sand flies) and have a wide host range that includes cattle, goats and sheep, wild ruminants, equids, camelids, marsupials, sloths, bats, birds, large canine and feline carnivores, and humans. The three economically most important orbiviruses are ''Bluetongue virus'', ''African horse sickness virus'', and ''Epizootic hemorrhagic disease virus'', all of which are transmitted by ''Culicoides'' species. The genus contains 22 species and at least 130 different serotypes. History In 1719, African horse sickness viru ...

Mediterranean Basin
In biogeography, the Mediterranean Basin (; also known as the Mediterranean Region or sometimes Mediterranea) is the region of lands around the Mediterranean Sea that have mostly a Mediterranean climate, with mild to cool, rainy winters and warm to hot, dry summers, which supports characteristic Mediterranean forests, woodlands, and scrub vegetation. Geography The Mediterranean Basin covers portions of three continents: Europe, Africa, and Asia. It is distinct from the drainage basin, which extends much further south and north due to major rivers ending in the Mediterranean Sea, such as the Nile and Rhône. Conversely, the Mediterranean Basin includes regions not in the drainage basin. It has a varied and contrasting topography. The Mediterranean Region offers an ever-changing landscape of high mountains, rocky shores, impenetrable scrub, semi-arid steppes, coastal wetlands, sandy beaches and a myriad islands of various shapes and sizes dotted amidst the clear blue sea.

Bluetongue Virus
Bluetongue disease is a noncontagious, insect-borne, viral disease of ruminants, mainly sheep and less frequently cattle, yaks, goats, buffalo, deer, dromedaries, and antelope. It is caused by ''Bluetongue virus'' (''BTV''). The virus is transmitted by the midges ''Culicoides imicola'', '' Culicoides variipennis'', and other culicoids. Signs In sheep, BTV causes an acute disease with high morbidity and mortality. BTV also infects goats, cattle, and other domestic animals, as well as wild ruminants (for example, blesbuck, white-tailed deer, elk, and pronghorn antelope). Major signs are high fever, excessive salivation, swelling of the face and tongue, and cyanosis of the tongue. Swelling of the lips and tongue gives the tongue its typical blue appearance, though this sign is confined to a minority of the animals. Nasal signs may be prominent, with nasal discharge and stertorous respiration. Some animals also develop foot lesions, beginning with coronitis, with c ...

Cattle Drive
A cattle drive is the process of moving a herd of cattle from one place to another, usually moved and herded by cowboys on horses. Europe In medieval central Europe, annual cattle drives brought Hungarian Grey cattle across the Danube River to the beef markets of Western Europe. In the 16th century the Swiss operated cattle drives over the St. Gotthard Pass to the markets in Bellinzona and Lugano and into Lombardy in northern Italy. The drives had ended by 1700 when sedentary dairy farming proved more profitable. In the eighteenth century up to 80,000 cattle were driven South from Scotland each year. From 1850 cattle trains were established from Aberdeen to London. Australia Australia is noted for long drives. Patsy Durack, for instance, left Queensland for the Kimberley in Western Australia in 1885 with 8,000 cattle, arriving with only half that number some two years and two months later, completing a drive of some 3,000 miles. Indeed, long cattle drives continued we ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Midge
A midge is any small fly, including species in several families of non-mosquito Nematoceran Diptera. Midges are found (seasonally or otherwise) on practically every land area outside permanently arid deserts and the frigid zones. Some midges, such as many Phlebotominae (sand fly) and Simuliidae (black fly), are vectors of various diseases. Many others play useful roles as prey for insectivores, such as various frogs and swallows. Others are important as detritivores, and form part of various nutrient cycles. The habits of midges vary greatly from species to species, though within any particular family, midges commonly have similar ecological roles. Examples of families that include species of midges include: * Blephariceridae, net-winged midges * Cecidomyiidae, gall midges * Ceratopogonidae, biting midges (also known as no-see-ums or punkies in North Americabr>BugGuide/ref> and sandflies in Australia) * Chaoboridae, phantom midges * Chironomidae, non-biting midges (a ...

Imago
In biology, the imago (Latin for "image") is the last stage an insect attains during its metamorphosis, its process of growth and development; it is also called the imaginal stage, the stage in which the insect attains maturity. It follows the final ecdysis of the immature instars.Carpenter, Geo. H., The Life-Story of Insects. Cambridge University Press 1913. May be downloaded from: https://www.gutenberg.org/ebooks/16410 or https://archive.org/details/thelifestoryofin16410gut In a member of the Ametabola or Hemimetabola, in which metamorphosis is "incomplete", the final ecdysis follows the last immature or '' nymphal'' stage. In members of the Holometabola, in which there is a pupal stage, the final ecdysis follows emergence from the pupa, after which the metamorphosis is complete, although there is a prolonged period of maturation in some species. The imago is the only stage during which the insect is sexually mature and, if it is a winged species, has functional wings. The i ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...
