Aedes Atlanticus
''Aedes atlanticus'' is a species of ''Aedes'' mosquito native to the southeastern United States of America. It is known for carrying a number of pathogens that can infect humans, most notably yellow fever. Description ''Ae. atlanticus'' is a medium-sized mosquito with prominent white stripes on its abdomen. The females of this species are pestiferous, like their aptly named close cousin ''Aedes tormentor''. In addition to being a vector of yellow fever, the mosquito can carry the Keystone virus, which is common in small animals in Florida, and may be common among humans with only minor symptoms, though only two cases have been verified, as of June 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 i ...

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] |

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are im ...

Aedes
''Aedes'' is a genus of mosquitoes originally found in tropical and subtropical zones, but now found on all continents except perhaps Antarctica. Some species have been spread by human activity: ''Aedes albopictus'', a particularly invasive species, was spread to the New World, including the United States, in the 1980s, by the used-tire trade. First described and named by German entomologist Johann Wilhelm Meigen in 1818, the generic name comes from the Ancient Greek ἀηδής, ''aēdēs'', meaning "unpleasant" or "odious". The type species for ''Aedes'' is '' Aedes cinereus''.. Systematics and phylogeny The genus was named by Johann Wilhelm Meigen in 1818. The generic name comes from the Ancient Greek ἀηδής, ''aēdēs'', meaning "unpleasant" or "odious". As historically defined, the genus contains over 700 species (see the list of ''Aedes'' species). The genus has been divided into several subgenera (''Aedes'', '' Diceromyia'', '' Finlaya'', ''Stegomyia'', etc.) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Of America
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations.

Yellow Fever
Yellow fever is a viral disease of typically short duration. In most cases, symptoms include fever, chills, loss of appetite, nausea, muscle pains – particularly in the back – and headaches. Symptoms typically improve within five days. In about 15% of people, within a day of improving the fever comes back, abdominal pain occurs, and liver damage begins causing yellow skin. If this occurs, the risk of bleeding and kidney problems is increased. The disease is caused by the yellow fever virus and is spread by the bite of an infected mosquito. It infects humans, other primates, and several types of mosquitoes. In cities, it is spread primarily by '' Aedes aegypti'', a type of mosquito found throughout the tropics and subtropics. The virus is an RNA virus of the genus ''Flavivirus''. The disease may be difficult to tell apart from other illnesses, especially in the early stages. To confirm a suspected case, blood-sample testing with polymerase chain reaction is required. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vector (epidemiology)
In epidemiology, a disease vector is any living agent that carries and transmits an infectious pathogen to another living organism; agents regarded as vectors are organisms, such as parasites or microbes. The first major discovery of a disease vector came from Ronald Ross in 1897, who discovered the malaria pathogen when he dissected a mosquito. Arthropods Arthropods form a major group of pathogen vectors with mosquitoes, flies, sand flies, lice, fleas, ticks, and mites transmitting a huge number of pathogens. Many such vectors are haematophagous, which feed on blood at some or all stages of their lives. When the insects feed on blood, the pathogen enters the blood stream of the host. This can happen in different ways. The '' Anopheles'' mosquito, a vector for malaria, filariasis, and various arthropod-borne-viruses (arboviruses), inserts its delicate mouthpart under the skin and feeds on its host's blood. The parasites the mosquito carries are usually located in its saliv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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."
