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, according to a new study published May 5 in the open-access journal PLoS Neglected Tropical Diseases. Dr Nigel Beebe and colleagues from the University of Queensland, CSIRO Entomology, the Australian Army Malaria Institute, and the Communicable Diseases Branch of Queensland...

For the first time ever, scientists are using DNA "barcodes" to help prevent the spread of a elephantiasis, an often disfiguring disease that affects roughly one billion people in 80 nations throughout the world. The University of Ghana is pioneering use of the "barcodes", which will be used to map mosquito species in West Africa that spread the disease, also known as lymphatic filariasis (LF). The underlying technology allows scientists to quickly and accurately distinguish species based on...

University of Adelaide researchers have shown they can predict the biggest population peaks of disease-carrying mosquitoes up to two months ahead. This should help the fight against outbreaks of serious mosquito-borne disease like dengue and Ross River fever by allowing efficient and cost-effective mosquito control, says ecologist Associate Professor Corey Bradshaw. "The risk of disease transmission is highest when mosquitoes are at their most abundant," says Associate Professor Bradshaw, who...

Isolongifolenone found as effective as DEET against mosquitoes and ticksIsolongifolenone, 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.  Derivatives of isolongifolenone have been widely and safely used as fragrances in cosmetics, perfumes, deodorants, and paper products, and...

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. But human behavior in the form of storing water to cope with climate change is likely to have an even greater impact. The potential direct impact of...

Ecologists have developed a new model to predict the impact of climate change on the dengue fever-carrying mosquito Aedes aegypti in Australia "“ information that could help limit its spread. According to the study, published in the new issue of the British Ecological Society's journal Functional Ecology, climate change and evolutionary change could act together to accelerate and expand the mosquito's range. But human behaviour "“ in the form of storing water to cope with climate...

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.Ronald R. Hoy, who authored a report about the study, said the discovery could pave the way to better methods of controlling mosquitoes.  Indeed, one such way to control mosquitoes is by releasing sterile males to prevent reproduction.  By monitoring their mating signals, researchers would have a way...

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. These findings can be found in the November issue of the American Journal of Tropical Medicine and Hygiene. Barry Alto, Ph.D., Director of the Medical Entomology Program at the Illinois Natural History Survey, along with Assistant Professor Michael Reiskind of Oklahoma...

No more big stink: Scent lures mosquitoes, but humans can't smell it A University of California, Davis research team led by chemical ecologist Walter Leal has discovered a low-cost, easy-to-prepare attractant that lures blood-fed mosquitoes without making humans hold their noses. The synthetic mixture, containing compounds trimethylamine and nonanal in low doses, is just as enticing to Culex mosquitoes as the current attractants, Leal said, but this one is odorless to humans. The research,...

Aedes is a genus of mosquito found in tropical and subtropical zones. The name comes from the Greek aēdēs, 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...
