An experimental research carried out in Sant Cugat del Valls and Rubí, coordinated by researchers from UAB, assessed the efficacy of a combination of strategies to reduce the population of tiger mosquitos (Aedes albopictus). The research began in February 2008. The research focused on monitoring eggs found in small experimental traps. Researchers observed that for the first time, the number of eggs diminished after applying the measures. The strategies began with a visit to...

Researchers probing genetics of chikungunya virus identify tiny changes separating epidemic African strain and tamer Asian variety What causes a virus to suddenly begin infecting large numbers of people? Scientists have long known that the process they call "viral emergence" involves a wide variety of factors. Some are changes in the environment, either generated by natural causes or human activity. Others are internal, arising from accidental changes "” mutations "”in the virus'...

There is a new player in the fight against dengue fever in Malaysia, 6,000 of them actually. Malaysia released about 6,000 genetically modified mosquitoes into a forest in the first experiment of its kind in Asia aimed at curbing dengue fever, officials said Wednesday to AP. The field test is meant to pave the way for the use of genetically engineered Aedes aegypti male mosquitoes to mate with females and produce no offspring or ones with shorter lives, hopefully curtailing the mosquito...

An official said on Tuesday that Malaysia has delayed a landmark field trial to release genetically modified mosquitoes designed to combat dengue fever. The 4,000 to 6,000 male Aedes aegypti mosquitoes were originally scheduled to be released last month in an attempt to fight dengue, which killed at least 134 people last year in Malaysia alone. The insects have been engineered so that their offspring quickly die, curbing the growth of the population in a technique researchers hope could...

Alexander Raikhel's lab identifies a microRNA molecule that controls blood feeding and egg development in Aedes aegypti femalesEach year, dengue fever infects as many as 100 million people while yellow fever is responsible for about 30,000 deaths worldwide. Both diseases are spread by infected female Aedes aegypti mosquitoes, which require vertebrate blood to produce eggs. The blood feeding and the egg development are tightly linked to how the mosquito transmits the disease-causing virus.Now...

British scientists have created genetically modified sterile mosquitoes in an experiment to kill off others in their species, and researchers are hopeful that early field trials could help to stave off the rapid spread of dengue fever. This is the first time genetically altered mosquitoes have been set loose in the wild, after years of lab experiments and calculations. But while scientists believe the trial could lead to a breakthrough in halting the disease, critics argue that mutant...

Scientists announced on Thursday that they had successfully sequenced the genome of the Southern house mosquito--the species of insect most responsible for the transmission of diseases such as West Nile virus, encephalitis, and elephantiasis. Writing in two separate papers published by the journal Science, a team of researchers from 39 universities in the United States and Europe reported that they had completely mapped the DNA of the Southern house mosquito, or Culex pipiens...

Dengue fever -- caused by a virus transmitted by mosquitoes -- threatens 2.5 billion people each year and there is no vaccine or treatment. New research by Michigan State University entomologists has found that a bacterium can stop dengue viruses from replicating in the mosquitoes. "In nature, about 28 percent of mosquito species harbor Wolbachia bacteria, but the mosquitoes that are the primary transmitters of dengue, Aedes aegypti, have no Wolbachia in them," said Zhiyong Xi, MSU assistant...

The potentially deadly yellow-fever-transmitting Aedes aegypti mosquito detects the specific chemical structure of a compound called octenol as one way to find a mammalian host for a blood meal, Agricultural Research Service (ARS) scientists report. Scientists have long known that mosquitoes can detect octenol, but this most recent finding by ARS entomologists Joseph Dickens and Jonathan Bohbot explains in greater detail how Ae. aegypti--and possibly other mosquito species--accomplish this....

ITHACA, N.Y. -- Cornell researchers have found a protein that may lead to a new way to control mosquitoes that spread dengue fever, yellow fever and other diseases when they feed on humans: Prevent them from urinating as they feed on blood. The work may lead to the development of new insecticides to disrupt the mosquito's renal system, which contributes to a mosquito's survival after feeding on blood. Aedes aegypti mosquitoes transmit the virus that causes dengue fever, putting 40...

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...
