Culex Erraticus
''Culex erraticus'', which translates in English to Erratic Mosquito, is a species of mosquito in the family Culicidae. It is widespread in Florida, but rare in the northeastern United States. The mosquito ranges in the north from Connecticut and Ontario, west to Nebraska, and south to Mexico, Central America, and South America. In addition, it is found in southernmost California. The females can be aggressive biters. They take blood meals from birds, mammals, amphibians, and reptiles. The mosquito is frequently infected with the virus EEEV, and may be a public health concern for its potential to transmit this arbovirus to people. ''Culex erraticus'' mosquitoes lay eggs in floating clusters called “egg rafts” on the surface of standing water, usually by laying them on the edges of aquatic plant leaves. These mosquitoes are known overwinter in gopher tortoise The gopher tortoise (''Gopherus polyphemus'') is a species of tortoise in the family Testudinidae. The species is ...

Mosquito
Mosquitoes, the Culicidae, are a Family (biology), family of small Diptera, flies consisting of 3,600 species. The word ''mosquito'' (formed by ''Musca (fly), mosca'' and diminutive ''-ito'') is Spanish and Portuguese for ''little fly''. Mosquitoes have a slender segmented body, one pair of wings, three pairs of long hair-like legs, and specialized, highly elongated, piercing-sucking mouthparts. All mosquitoes drink nectar from flowers; females of some species have in addition adapted to drink blood. The group diversified during the Cretaceous period. Evolutionary biology, Evolutionary biologists view mosquitoes as micropredators, small animals that Parasitism, parasitise larger ones by drinking their blood without immediately killing them. Parasitology, Medical parasitologists view mosquitoes instead as Disease vector, vectors of disease, carrying protozoan parasites or bacterial or virus, viral pathogens from one Host (biology), host to another. The mosquito life cycle cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EEEV
Eastern equine encephalitis (EEE), also called triple E and sleeping sickness, is a viral disease caused mainly by the Eastern equine encephalitis virus (EEEV). Most infections in humans are asymptomatic, but about 5% of the time the infection progresses to severe neuroinvasive disease. Symptoms typically appear 3–10 days after being bitten by an infected mosquito and initially include fever, headache, nausea, vomiting, fatigue, muscle pain, and joint pain. Neurological symptoms usually appear a few days later and include altered mental state, encephalitis, photophobia, seizures, paralysis, and loss of consciousness and coma. The case fatality rate is 30–75% depending on age, with disease severity greatest in young children and the elderly. About 50 to 90% of survivors experience long-term neurological complications that range from minor to severe. EEE is most common in horses, in which the disease carries a 70–90% case fatality rate and permanent brain damage for survivors. ...

Arbovirus
Arbovirus is an informal name for any virus that is Transmission (medicine), transmitted by arthropod Vector (epidemiology), vectors. The term ''arbovirus'' is a portmanteau word (''ar''thropod-''bo''rne ''virus''). ''Tibovirus'' (''ti''ck-''bo''rne ''virus'') is sometimes used to more specifically describe viruses transmitted by ticks, a superorder within the arthropods. Arboviruses can affect both animals (including humans) and plants. In humans, symptoms of arbovirus infection generally occur 3–15 days after exposure to the virus and last three or four days. The most common clinical features of infection are fever, headache, and malaise, but encephalitis and viral hemorrhagic fever may also occur. Signs and symptoms The incubation period – the time between when infection occurs and when symptoms appear – varies from virus to virus, but is usually limited between 2 and 15 days for arboviruses. The majority of infections, however, are asymptomatic. Among cases in which sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overwinter
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not necessarily by cold but by dry conditions; passing through such periods could likewise be called overwintering. Hibernation and migration are the two major ways in which overwintering is accomplished. Animals may also go into a state of reduced physiological activity known as torpor. Overwintering occurs in several classes of lifeform. Insects In entomology, overwintering is how an insect passes the winter season. Many insects overwinter as adults, pupae, or eggs. This can be done inside buildings, under tree bark, or beneath fallen leaves or other plant matter on the ground, among other places. All such overwintering sites shield the insect ...

Gopher Tortoise
The gopher tortoise (''Gopherus polyphemus'') is a species of tortoise in the family Testudinidae. The species is native to the southeastern United States. The gopher tortoise is seen as a keystone species because it digs burrows that provide shelter for at least 360 other animal species. ''G. polyphemus'' is threatened by predation and habitat destruction. Habitat degradation is the primary reason that the gopher tortoise is listed as vulnerable on the IUCN Red List, but they are considered threatened in some states while they are endangered in others. The gopher tortoise is a representative of the genus ''Gopherus'', which contains the only tortoises native to North America. The gopher tortoise is the state reptile of Georgia and the state tortoise of Florida. Etymology Tortoises of the genus ''Gopherus'' are so named because of some species' habit of digging large, deep burrows like those of gophers. The specific name, ''polyphemus'', refers to the cave-dwelling giant, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Culex
''Culex'' or typical mosquitoes are 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 used 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 mod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
