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...

Every homeowner needs to help in the fight against mosquitoes. Controlling the mosquito population is a collective effort. The key to removing mosquitoes is removing standing water, their breeding habitat. Mosquitoes don't need much water to breed. Even the water collected in old bottles and cans is enough. And mosquitoes don't need much time to develop -- only a week from egg to adulthood. With this combination of little water and little time, a small mosquito problem can quickly...

A new study by a team of University of Notre Dame researchers offers a wealth of information about the rhythmic nature of gene expression in Anopheles gambiae, the mosquito species that transmits the malaria parasite from person to person. Each year, roughly 250 million people suffer from malaria and that results in one million deaths, mostly pregnant women and children under five years of age. Mosquitoes, like all animals, show daily rhythms in behavior and physiology. The rhythmic behaviors...

Dengue virus circulating between monkeys and mosquitoes could emerge to cause human outbreaks More than a thousand years ago, somewhere in Southeast Asia, a fateful meeting occurred between a mosquito-borne virus that infected mainly monkeys and a large, susceptible group of humans. The result: the world's first outbreak of dengue fever. Today, dengue virus "” which can produce high fever, excruciating joint pain and even death "” has spread throughout tropical Asia, Africa and...

In a dramatic breakthrough in the battle against malaria, researchers have identified a low-cost chemical that interferes with a mosquito's ability to detect humans, scientists said on Wednesday. Experts hope the findings could help develop the next generation of mosquito traps and repellents, which could confuse, deter or trap the insects. The chemicals consist of odor molecules that disrupt carbon-dioxide sensors that alert mosquitoes to exhaled human breath, which signals the presence of a...

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'...

Scientists have discovered a new type of mosquito that is unlike any that have been documented before and could complicate the fight against malaria even further. Scientists from France collected mosquitoes from ponds near villages in Burkina Faso over a four-year period and said they identified some as a subtype of Anopheles gambiae -- which is responsible for most malaria transmissions in Africa. The new subtype is highly susceptible to infection with the malaria parasite and, because it...

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...

In notable back-to-back papers appearing in the prestigioous journal Science in October, teams of researchers, one led by Nora Besansky, a professor of biological sciences and a member of the Eck Institute for Global Health at the University of Notre Dame, provided evidence that Anopheles gambiae, which is one of the major mosquito carriers of the malaria parasite in Sub-Saharan Africa, is evolving into two separate species with different traits. Another significant study appearing in this...

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...
