Culex Bitaeniorhynchus
''Culex (Oculeomyia) bitaeniorhynchus'' is a species of mosquito belonging to the genus ''Culex''. It is a cosmopolitan species which can be found in all continents, except America and Antarctica. Bionomics Larva can be found in pools with stagnant waters containing ''Spirogyra''. Females are blood feeders of birds and sometimes humans. Adults and larva can be naturally infected with ''Wuchereria bancrofti'' and Batai virus ''Batai orthobunyavirus'' (BATV) is a RNA virus belonging to order ''Bunyavirales'', genus ''Orthobunyavirus''. Introduction Batai virus (BATV) is an enveloped, single-stranded, negative sense RNA genome. It is a member of the genus Orthobunyavir ... in India, and '' Burgia malayi'' in Sri Lanka. It can also infect Murray Valley encephalitis in Australia.

Mosquito
Mosquitoes (or mosquitos) are members of a group of almost 3,600 species of small flies within the family Culicidae (from the Latin ''culex'' meaning " gnat"). The word "mosquito" (formed by ''mosca'' and diminutive ''-ito'') is Spanish for "little fly". Mosquitoes have a slender segmented body, one pair of wings, one pair of halteres, three pairs of long hair-like legs, and elongated mouthparts. The mosquito life cycle consists of egg, larva, pupa, and adult stages. Eggs are laid on the water surface; they hatch into motile larvae that feed on aquatic algae and organic material. These larvae are important food sources for many freshwater animals, such as dragonfly nymphs, many fish, and some birds such as ducks. The adult females of most species have tube-like mouthparts (called a proboscis) that can pierce the skin of a host and feed on blood, which contains protein and iron needed to produce eggs. Thousands of mosquito species feed on the blood of various hosts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Culex
''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, incon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spirogyra
''Spirogyra'' (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. ''Spirogyra'' species, of which there are more than 400, are commonly found in freshwater habitats. ''Spirogyra'' measures approximately 10 to 100 μm in width and may grow to several centimetres in length. It is often observed as green slimy patches on the ground near ponds and other water bodies having stagnant water. General characteristics ''Spirogyra'' is very common in relatively clear eutrophic water, developing slimy filamentous green masses. In spring ''Spirogyra'' grows under water, but when there is enough sunlight and warmth they produce large amounts of oxygen, adhering as bubbles between the tangled filaments. The filamentous masses come to the surface and become visible as slimy green mats. ''Spirogyr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wuchereria Bancrofti
''Wuchereria bancrofti'' is a filarial (arthropod-borne) nematode (roundworm) that is the major cause of lymphatic filariasis. It is one of the three parasitic worms, together with ''Brugia malayi'' and '' B. timori'', that infect the lymphatic system to cause lymphatic filariasis. These filarial worms are spread by a variety of mosquito vector species. ''W. bancrofti'' is the most prevalent of the three and affects over 120 million people, primarily in Central Africa and the Nile delta, South and Central America, the tropical regions of Asia including southern China, and the Pacific islands. If left untreated, the infection can develop into lymphatic filariasis. In rare conditions, it also causes tropical pulmonary eosinophilia. No vaccine is commercially available, but high rates of cure have been achieved with various antifilarial regimens and lymphatic filariasis is the target of the World Health Organization Global Program to Eliminate Lymphatic Filariasis with the aim to erad ...

Batai Virus
''Batai orthobunyavirus'' (BATV) is a RNA virus belonging to order ''Bunyavirales'', genus ''Orthobunyavirus''. Introduction Batai virus (BATV) is an enveloped, single-stranded, negative sense RNA genome. It is a member of the genus Orthobunyavirus and belongs to the order Bunyavirales; it was first isolated from Culex mosquitoes in Malaysia in 1955. Evidence from serological surveillance and virus isolation shows that this virus is widely distributed around the world. Similar to other orthobunyaviruses it contributes to both human and animal disease. In humans it has been noted in causing severe fever, and in bovines has been associated with premature birth, birth defects, and increased abortion rates. It is transmitted through mosquito bites, ticks, and biting midges, and occurs from cold to tropical regions of Africa, Asia, and Europe. Structure The structure of Batai virus (BATV) consists of an enveloped nucleocapsid that is composed of three RNA segments: small (S), medium ...
