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...

Researchers have developed the first animal model of the infection caused by chikungunya virus (CHIKV), an emerging arbovirus associated with large-scale epidemics that hit the Indian Ocean (especially the French Island of La R©union) in 2005, later spreading to India, and Italy in 2007. Using this mouse model, scientists of the Institut Pasteur and INSERM determined which tissues and cells are infected by the virus in both the mild and severe forms of the disease it causes. They detail...

Few things sting like a mosquito's bite -- especially if that bite carries a disease such as malaria, yellow fever, Dengue fever or West Nile virus. But if researchers from The University of Arizona in Tucson have their way, one day mosquito bites may prove deadly to the mosquitoes as well. "Our goal is to turn the female mosquito's blood meal into the last meal she ever eats," said project leader Roger L. Miesfeld, a professor of biochemistry and molecular biophysics in UA's College of...

Without mosquitoes, epidemics of dengue fever and malaria could not plague this planet. The skin-piercing insects infect one person after another while dining on a favorite meal: human blood. Eliminating the pests appears impossible. But scientists are attempting to re-engineer them so they cannot carry disease. If they manage that, they must create enough mutants to mate with wild insects and one day to outnumber them. Researchers chasing this dream, including an N.C. State University...

RIO DE JANEIRO, Brazil (Reuters) - An outbreak of dengue fever in Brazil's tourist mecca of Rio de Janeiro has prompted the authorities to step up prevention measures, fearing a repeat of a 2002 epidemic that killed more than 100 people, officials said on Wednesday. "We have flare-ups in two districts. It needs to be blocked urgently, because without such control we have a risk of having an epidemic again in Rio," Aloisio Ribeiro, head of Rio state government's Epidemiology Vigilance...

SINGAPORE (Reuters) - Singapore, fighting its worst dengue epidemic, is optimistic that the number of cases had peaked and will dip in the coming months, a panel of health experts said on Saturday. Twelve Singaporeans have died from the mosquito-borne disease this year and 10,951 cases of dengue fever were reported by September 24 -- 16 percent more than the total number recorded last year when dengue infections rocketed to a 10-year high. "Looking at the trend, it looks like it...

SINGAPORE (Reuters) - Seven people have died of dengue fever in Singapore this year and the number of new cases in the city-state hit a new high last week despite government efforts to clear out mosquito breeding grounds. The weekly bulletin on infectious disease by Singapore's Health Ministry showed 493 new dengue cases reported in the week ending August 28, up nearly a fifth from the previous week's record high of 414, the government said on Thursday. The government has launched a...
