Aedes Infirmatus
''Aedes infirmatus'', informally referred to as the infirm American pointy mosquito or silverback mosquito, is a species of mosquito that is found in woodland environments in parts of Central America, Mexico, and the southern United States, with a type locality in Baton Rouge, Louisiana. In the United States, they have been found as far west as Texas and as far north as New Jersey. Description Adults of the species have a dark-scaled proboscis, dark legs, and a broad silvery white patch on their thorax which helps distinguish them from other species of similar appearance. Life cycle Females of this species typically lay their eggs in low-lying grassy areas prone to flooding; the eggs are stimulated to hatch by flooding which often takes place in the spring. Adults will opportunistically feed on passing hosts, including humans, in the woodland environments where their populations are most dense, but only rarely enter buildings. Studies in northeastern Florida found a negati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frederick Knab
Frederick Knab (September 22, 1865 – November 2, 1918) was an artist and entomologist active from the 1880s through the 1918, most noted for his oil paintings and illustrations and his work with coleopterous and dipterous insects. Knab was born September 22, 1865, in Würzburg, Bavaria and came to the United States as a boy of eight with his parents, Oscar and Josephine Knab, who settled in Chicopee, Massachusetts in 1873. His father was an engraver and painter and an uncle was court painter to the King of Bavaria. In his youth, Knab showed artistic talent and a strong interest in the natural sciences, especially entomology. He studied the classic works of Charles Darwin, Alfred Russel Wallace, and Henry Walter Bates and accumulated a large collection of insects, particularly beetles (Order Coleoptera), and became an active member of the Springfield (Massachusetts) Zoological Club and an active correspondent with other coleopterists. In 1885, Knab undertook a sixteen m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Culex Mosquito Life Cycle En
''Culex'' is a genus of mosquitoes, several species of which serve as vectors of one or more important diseases of birds, humans, and other animals. The diseases they vector include arbovirus infections such as West Nile virus, Japanese encephalitis, or St. Louis encephalitis, but also filariasis and avian malaria. They occur worldwide except for the extreme northern parts of the temperate zone, and are the most common form of mosquito encountered in some major U.S. cities, such as Los Angeles. Etymology In naming this genus, Carl Linnaeus appropriated the nonspecific Latin term for a midge or gnat: '. Description Depending on the species, the adult ''Culex'' mosquito may measure from . The adult morphology is typical of flies in the suborder Nematocera with the head, thorax, and abdomen clearly defined and the two forewings held horizontally over the abdomen when at rest. As in all Diptera capable of flight, the second pair of wings is reduced and modified into tiny, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Encephalitis Virus
''California encephalitis orthobunyavirus'' type strain California encephalitis virus was discovered in Kern County, California, and causes encephalitis in humans. Encephalitis is an acute inflammation of the brain that can cause minor symptoms, such as headaches, to more severe symptoms such as seizures. Mosquitoes serve as its carrier and for this reason this virus is known as an arbovirus (arthropod-borne virus). ''California encephalitis orthobunyavirus'' belongs to the '' Bunyavirales'' order of viruses. The La Crosse Virus from the same genus is also a common cause of encephalitis in the United States. Other viruses with similar disease symptoms but genetically unrelated include: Saint Louis encephalitis and West Nile virus. Signs and symptoms The incubation period of California encephalitis is usually 3–7 days. An early symptoms phase of 1–4 days commonly precedes the onset of encephalitis, manifesting as fever, chills, nausea, vomiting, headache, lethargy and abdom ...

Keystone Virus
Keystone virus (''Keystone orthobunyavirus'') is a mosquito-borne virus which can infect mammals. It was first discovered in animals in the Florida area, where it is spread in part by local species of ''Aedes'' mosquitoes. In 1964, a case of human infection, producing minor symptoms of a rash and fever, was circumstantially diagnosed. Conclusive laboratory demonstration of the virus in humans was first obtained and reported in 2018.Ashley May: "Keystone virus makes first jump from mosquitoes to humans with confirmed case in Florida teen, study says," https://www.usatoday.com/story/news/nation-now/2018/06/22/first-report-human-keystone-virus-found-florida-teen/725460002/, updated 1:20 p.m. ET June 25, 2018; "Authors said this was the first case of the virus in humans, but the Florida Department of Health told USA TODAY that a young child from Sarasota had the virus in 1964."

West Nile Virus
West Nile virus (WNV) is a single-stranded RNA virus that causes West Nile fever. It is a member of the family ''Flaviviridae'', from the genus ''Flavivirus'', which also contains the Zika virus, dengue virus, and yellow fever virus. The virus is primarily transmitted by mosquitoes, mostly species of '' Culex''. The primary hosts of WNV are birds, so that the virus remains within a "bird–mosquito–bird" transmission cycle. The virus is genetically related to the Japanese encephalitis family of viruses. Humans and horses both exhibit disease symptoms from the virus, and symptoms rarely occur in other animals. Identification of the human disease was first made in 1937 in Uganda and in the latter half of the 20th century spread to many other parts of the world. Structure Like most other flaviviruses, WNV is an enveloped virus with icosahedral symmetry. Electron microscope studies reveal a 45–50 nm virion covered with a relatively smooth protein shell; this structur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
