Latest Culicidae Stories
In a drama played out across the southeastern U.S. in containers as small as a coffee cup, native and invasive mosquito larvae compete for resources and try to avoid getting eaten. One of the invasive mosquitoes, the Asian tiger mosquito (Aedes albopictus), can carry dengue fever, a viral disease that sickens 50 to 100 million people a year in the tropics, so this seemingly inconsequential struggle has implications for human health.
Australian scientists are blaming humans for their nation's dengue risks and say installing large water tanks in urban regions might make the problem worse. The researchers, led by Nigel Beebe from the University of Queensland, said such domestic water tanks would enable the dengue mosquito (Aedes aegypti) to regain its foothold across the country and expand its range of possible infections. Beebe and colleagues from the Commonwealth Scientific and Industrial Research Organization, the...
'Drought-proofing' Australia's urban regions by installing large domestic water tanks may enable the dengue mosquito Aedes aegypti to regain its foothold across the country and expand its range of possible infections.
For the first time ever, scientists are using DNA â€œbarcodesâ€ to help prevent the spread of a elephantiasis, an often disfiguring disease that affects roughly one billion people in 80 nations throughout the world.
University of Adelaide researchers have shown they can predict the biggest population peaks of disease-carrying mosquitoes up to two months ahead.
Isolongifolenone, a natural compound found in the Tauroniro tree (Humiria balsamifera) of South America, has been found to effectively deter biting of mosquitoes and to repel ticks, both of which are known spreaders of diseases such as malaria, West Nile virus, and Lyme disease.
Australian scientists say hoarding water as climate change intensifies might aid the dengue fever-carrying mosquito Aedes aegypti in extending its range. The lead author of the study, Michael Kearney of the University of Melbourne, said climate change and evolutionary change could act together to accelerate and expand the mosquito's range.
Ecologists have developed a new model to predict the impact of climate change on the dengue fever-carrying mosquito Aedes aegypti in Australia â€“ information that could help limit its spread.
New research from Cornell University finds that Aedes aegypti mosquitoes, the kind that spread diseases such as dengue and yellow fever, change their wing vibrations as a mating symbol.
An entomologist at the Illinois Natural History Survey, a division of the new UI Institute for Natural Resource Sustainability, says smaller mosquitoes are more likely to be infected with viruses that cause diseases in humans.
Aedes is a genus of mosquito found in tropical and subtropical zones. The name comes from the Greek aÄ“dÄ“s, meaning unpleasant, so called because of the diseases this mosquito transmits, which include dengue and yellow fever. There are presently some controversial moves afoot to abolish Aedes as a generic name and to replace it with Stegomyia. Currently, the Aedes aegypti genome is being sequenced by TIGR, The Institute for Genomic Research.
Aedes albopictus (Family Culicidae), the Asian Tiger Mosquito or Forest Day Mosquito, is characterized by its black and white striped legs and small, black and white body. It was native to south-east Asia, and occupied a habitat that spread from Madagascar eastward to New Guinea, and north to the latitude of Korea. The typical member of the Aedes albopictus has a length of about 5 mm. As with other members of the mosquito family, the female is outfitted with an elongated proboscis that she...
The mosquito is a member of the family Culicidae. These insects have a pair of scaled wings, a pair of halteres, a slender body, and long legs. Only the females of most mosquito species suck blood from other animals. Size varies but is rarely greater than 0.6 inch (15 mm). Mosquitoes weigh only about 0.03 to 0.04 grain (2 to 2.5 mg). They can fly at about 0.9 to 1.6 mph (1.5 to 2.5 km/h) and most species are nocturnal. Mosquitoes are believed to have evolved 170 million years ago during...
