Deerfly
Chrysopsinae is an insect subfamily in the family Tabanidae commonly known as deer flies or sheep flies and are bloodsucking insects considered pests to humans and cattle. They are large flies with large brightly-coloured compound eyes, and large clear wings with dark bands. They are larger than the common housefly and smaller than the horse-fly. Deer flies lay between 100 and 800 eggs on vegetation near water or dampness in batches. During the larval stage, which lasts one to three weeks, they feed on small creatures or rotting organic matter near or in the water. After a pupal stage, they emerge as adults in late spring and summer. While male deer flies collect pollen, female deer flies feed on blood, which they require to produce eggs. Females feed primarily on mammals. They are attracted to prey by sight, smell, or the carbon dioxide detection. Other attractants are body heat, movement, dark colours, and lights in the night. They are active under direct sunshine and hours whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysops
Deer flies (also known in some parts of the Mid-Atlantic (United States), mid-Atlantic United States as sheep flies) are Hematophagy, bloodsucking insects considered Pest (organism), pests to humans and cattle. They are large flies with large brightly coloured compound eyes, and large clear wings with dark bands. They are larger than the common housefly and smaller than the horse fly. There are 250 species of deer fly in the genus ''Chrysops''. Their distribution is worldwide, though they have not been reported in Iceland, Greenland, or Hawaii. Deer flies lay between 100 and 800 eggs in batches on vegetation near water or dampness. During the larval stage, which lasts one to three years, they feed on small creatures or rotting organic matter near or in the water. After a pupal stage, they emerge as adults in late spring and summer. While male deer flies collect pollen, female deer flies feed on blood, which they require to produce eggs. Females feed primarily on mammals. They are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tularemia
Tularemia, also known as rabbit fever, is an infectious disease caused by the bacterium '' Francisella tularensis''. Symptoms may include fever, skin ulcers, and enlarged lymph nodes. Occasionally, a form that results in pneumonia or a throat infection may occur. The bacterium is typically spread by ticks, deer flies, or contact with infected animals. It may also be spread by drinking contaminated water or breathing in contaminated dust. It does not spread directly between people. Diagnosis is by blood tests or cultures of the infected site. Prevention includes the use of insect repellent and long pants, rapidly removing ticks, and not disturbing dead animals. Treatment is typically with the antibiotic streptomycin. Gentamicin, doxycycline, or ciprofloxacin may also be used. Between the 1970s and 2015, around 200 cases were reported in the United States a year. Males are affected more often than females. It occurs most frequently in the young and the middle aged. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harold Oldroyd
Harold Oldroyd (24 December 1913 – 3 September 1978) was a British entomologist. He specialised in the biology of flies, and wrote many books, especially popular science that helped entomology to reach a broader public. His ''The Natural History of Flies'' is considered to be the "fly Bible". Although his speciality was the Diptera, he acknowledged that they are not a popular topic: "Breeding in dung, carrion, sewage and even living flesh, flies are a subject of disgust...not to be discussed in polite society". It was Oldroyd who proposed the idea of hyphenating the names of true flies (Diptera) to distinguish them from other insects with "fly" in their names. Thus, the "house-fly", " crane-fly" and " blow-fly" would be true flies, while the "dragonfly", " scorpion fly" and so on belong to other orders. He also debunked the calculation that a single pair of house-flies, if allowed to reproduce without inhibitions could, within nine months, number 5.6 trillion individuals, enough t ...

Killdeer
The killdeer (''Charadrius vociferus'') is a large plover found in the Americas. Its shrill, two-syllable call is often heard, sounding like "kill deer". It was described and given its current scientific name in 1758 by Carl Linnaeus in the 10th edition of his ''Systema Naturae''. Three subspecies are described. Its are mostly brown with rufous fringes, the head has patches of white and black, and two black bands cross the breast. The belly and the rest of the breast are white. The nominate (or originally described) subspecies breeds from southeastern Alaska and southern Canada to Mexico. It is seen year-round in the southern half of its breeding range; the subspecies ''C. v. ternominatus'' is resident in the West Indies, and ''C. v. peruvianus'' inhabits Peru and surrounding South American countries throughout the year. North American breeders winter from their resident range south to Central America, the West Indies, and the northernmost portions of South America. The nonb ...

DEET
''N'',''N''-Diethyl-''meta''-toluamide, also called diethyltoluamide or DEET (, from DET, the initials of di- + ethyl + toluamide), is the oldest, one of the most effective, and most common active ingredients in commercial insect repellents. It is a slightly yellow oil intended to be applied to the skin or to clothing and provides protection against mosquitoes, flies, ticks, fleas, chiggers, leeches, and many other biting insects. Effectiveness DEET is effective against a variety of invertebrates, including ticks, flies, mosquitos, and some parasitic worms. A 2018 systematic review found no consistent performance difference between DEET and icaridin in field studies and concluded that they are equally preferred mosquito repellents, noting that 50% DEET offers longer protection but is not available in some countries. Concentrations The concentration of DEET in products may range from less than 10% to nearly 100%, but concentrations greater than 50% do not increase the du ...

Filariasis
Filariasis is a filarial infection caused by parasitic nematodes (roundworms) spread by different vectors. They are included in the list of neglected tropical diseases. The most common type is lymphatic filariasis caused by three species of '' Filaria'' that are spread by mosquitoes. Other types of filariasis are onchocerciasis also known as ''river blindness'' caused by '' Onchocerca volvulus''; Loa loa filariasis (Loiasis) caused by '' Loa loa''; Mansonelliasis caused by three species of '' Mansonella'', and Dirofilariasis caused by two types of '' Dirofilaria''. Epidemiology In the year 2000, 199 million infection cases of lymphatic filariasis were predicted with 3.1 million cases in America and around 107 million in South East Asia, making up to 52% of the global cases coming from Bangladesh, India, Indonesia, and Myanmar combined. While the African nations that comprised around 21% of the cases showed a decrease in the trend over a period of 19 years from 2000 to ...
