Latest Anopheles Stories
Scientists have developed a method of genetically manipulating large populations of mosquitoes, which could one day be used to significantly reduce the spread of the deadly malaria parasite to humans.
Scientists at Imperial College London and the University of Washington, Seattle, have taken an important step towards developing control measures for mosquitoes that transmit malaria.
Spraying malaria-transmitting mosquitoes with a genetically modified fungus can kill the malaria parasite without harming the mosquito, potentially reducing malaria transmission to humans.
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.
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.
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 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.
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.
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.
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...
