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...

Old mosquitoes are normally a catalyst in the spread of disease, so scientists from Australia have found a way to kill mosquitoes naturally by breeding them to carry an insect parasite that causes earlier death. Until now, scientists had been searching for a way to genetically engineer mosquitoes to become resistant to illnesses like dengue fever and malaria. When mosquitoes contract a disease like malaria or dengue, it takes two weeks of incubation before the insect can spread the illness...

Research conducted at The University of Queensland could contribute to the development of a vaccine and cure for West Nile virus and Dengue fever. Led by Associate Professor Alexander Khromykh, a team of researchers from UQ's School of Molecular and Microbial Sciences identified a novel characteristic of the virus family to which these diseases belong. The team found all flaviviruses produced a small molecule which, among other functions, controlled the host's response to viral infection....

In a global world, significant factors affect the spread of infectious diseases, including international trade, air travel and globalized food production. "Airport malaria" is a term coined by researchers to explain the more recent spread of malaria to areas such as the United States and Europe, which some scientists credit to warmer climate changes. Airport malaria is transmitted when a mosquito infected with the disease bites a human within the vicinity (usually one mile or less) of an...

Air travel, international trade and globalized food production are helping "airport malaria" and other diseases spread to the United States, researchers say. Dr. James H. Diaz of Louisiana State University said airport malaria is transmitted when a mosquito infected with the disease bites a human within the vicinity of an international airport. Climate changes in some U.S. cities with a large presence of international air traffic, such as New York and Los Angeles, seem to have created a...

U.S. entomologists say they've determined smaller mosquitoes are more likely to be infected with viruses causing human diseases than are larger mosquitoes. The researchers said they fed mosquitoes blood contaminated with the dengue virus and later tested them for infection at the Florida Medical Entomology Laboratory, taking into account the size of each mosquito by measuring the length of their wings. They discovered smaller-sized mosquitoes had higher infection rates and greater...

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...

By Anand Bodh Mohali: It seems that the government woke up only after a relative of a minister was down with dengue. A day after health minister Laxmi Kanta Chawla's relative in Mohali was admitted to PGI, Chandigarh, as a suspected dengue case, chief minister Parkash Singh Badal on Saturday announced free treatment for all such patients in government hospitals and dispensaries. He also directed chief secretary Ramesh Inder Singh to ask the health and medical services to gear up for any...

West Nile virus (WNV) is a virus of the family Flaviviridae. It is part of the Japanese encephalitis antigenic complex of viruses and is found in both tropical and temperate regions. It primarily infects birds but can infect humans, horses, dogs, cats, bats, and other mammals. Humans are generally infected through the bites of mosquitoes and about 90% of West Nile Virus infections are without symptoms. The virion is 45-60 nm and covered with a relatively smooth protein surface. It is...

Dengue fever and dengue hemorrhagic fever (DHF), caused by the dengue virus, is among the spectrum of acute febrile tropical disease and is transmitted by mosquitoes. Occurring mainly in the tropics it can be life threatening and is caused by four closely related virus stereotypes of the genus Flavivirus. It was identified and named in 1779. It has a nickname of "breakbone fever" due to it causing sever generalized bodyache. It tends to be more prevalent in the urban districts of its range...

Flavivirus is a genus of the family Flaviviridae. This genus includes the West Nile Virus, Dengue Virus, Tick-borne Encephalitis virus, yellow fever virus, and quite a few others. Flaviviruses get their name from the yellow fever virus. Flavus means yellow in Latin. Yellow fever was named because if caused yellow jaundice in victims. Mosquitoes and ticks transmit these viruses by biting people. Human infections are usually incidental since humans are unable to replicate the virus. Yellow...

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...
