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...

Research carried out in Mali, West Africa, has demonstrated that a new, safe and uncomplicated insect control method, developed at the Hebrew University of Jerusalem, can bring about a serious decline in malaria-bearing mosquitoes in afflicted regions in the world. The research in Africa was based on work carried out earlier in Israel by researchers at the Kuvin Center for the Study of Tropical and Infectious Diseases at the Hebrew University of Jerusalem that showed how attractants of plant...

The development and first use of a high-density SNP array for the malaria vector mosquito have established 400,000 genetic markers capable of revealing new insights into how the insect adapts to outsmart insecticides and other preventive measures, according to findings published in the current edition of the journal Science. The SNP array's snapshot of the Anopheles gambiae genome can be used by scientists worldwide to advance public health efforts to contain and eliminate the deadly disease,...

WHAT: Researchers funded by the National Institutes of Health have found that the major malaria-transmitting mosquito species, Anopheles gambiae, is evolving into two separate species with different traits, a development that could both complicate malaria control efforts and potentially require new disease prevention methods. Their findings were published in back-to-back articles in the October 22 issue of the journal Science. A. gambiae is the most common vector of human malaria in...

Two strains of the type of mosquito responsible for the majority of malaria transmission in Africa have evolved such substantial genetic differences that they are becoming different species, according to researchers behind two new studies published today in the journal Science. Over 200 million people globally are infected with malaria, according to the World Health Organisation, and the majority of these people are in Africa. Malaria kills one child every 30 seconds. Today's international...

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...

A new technique pioneered at Liverpool School of Tropical Medicine (LSTM) is improving the detection and monitoring of insecticide resistance in field populations of an important malaria-carrying mosquito. Researchers at LSTM, led by Dr Charles Wondji have developed a new technique which encourages the female Anopheles funestus mosquitoes to lay eggs which are then reared into adult mosquitoes to provide sufficient numbers to determine levels of insecticide resistance and to characterize the...

By David F. Salisbury Origin of DEET's repellent effect confirmed It now appears that the malaria mosquito needs more than one family of odor sensors to sniff out its human prey. That is the implication of new research into the mosquito's sense of smell published in the Aug. 31 issue of the online, open-access journal Public Library of Science Biology. The experiments described in the paper provide striking new evidence that Anopheles gambiae "“ the species of mosquito that spreads...

Scientists at the University of Oregon have determined the fine-scale genetic structure of the first animal to show an evolutionary response to rapid climate change. They used a high-throughput sequencing technique called Restriction-site Associated DNA (RAD) tagging to make the discovery. Their results, which focus on the pitcher plant mosquito, Wyeomyia smithii, are published this week in the journal Proceedings of the National Academy of Sciences (PNAS). RAD tagging is an effective and...

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...
