Study in Benin, Africa finds indoor spraying with the insecticide bendiocarb reduced infectious mosquito bites to near zero; and offers effective tool for malaria control strategy in areas rife with pyrethroid-resistance Indoor spraying with the insecticide bendiocarb has dramatically decreased malaria transmission in many parts of Benin, new evidence that insecticides remain a potent weapon for fighting malaria in Africa despite the rapid rise of resistance to an entire class of...

The incidence of malaria in many African countries south of the Sahara is falling rapidly. A Danish-Tanzanian research group has discovered that the mosquito carrying the malaria parasite has practically disappeared from villages without organized mosquito control, and the researchers do not know why. There are several hypotheses but without proper data they cannot say whether malaria is being eradicated or whether it is just resting up before returning with renewed vigour. "Many of our...

Memorandum of Understanding focused on USAID support of IDRI Collaboration with Walter Reed Army Institute of Research SEATTLE, Aug. 16, 2011/PRNewswire-USNewswire/ -- The Infectious Disease Research Institute (IDRI) today announced a new Memorandum of Understanding with the United States Agency for International Development (USAID), focused on support of a collaboration with the Walter Reed Army Institute of Research (WRAIR) for the development of a new vaccine against malaria. The...

Scientists have created spermless mosquitoes in an effort to curb the spread of malaria. Experts say this could be an important step to reducing the mosquito populations in the wild. Malaria kills about a million people around the world every year and accounts for 20 percent of all childhood deaths in Africa. Scientists injected 10,000 mosquito embryos with tiny fragments of RNA designed to turn off a gene known as zpg. The researchers created about 100 spermless mosquitoes that females...

ROCKVILLE, Md., June 29, 2011 /PRNewswire-USNewswire/ -- Sanaria's mission is to develop and commercialize whole-parasite malaria vaccines that confer high-level, long-lasting protection against malaria caused by Plasmodium falciparum and P. vivax. In the process of developing these vaccines, Sanaria has developed the capacity to manufacture and assay malaria parasites and mosquitoes in a highly regulated, cGMP compliant, industrial setting. These parasites, mosquitoes, and assay services...

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...

Wolbachia are bacteria that infect many insects, including mosquitoes. However, Wolbachia do not naturally infect Anopheles mosquitoes, which are the type that spreads malaria to humans. Researchers at the Johns Hopkins Bloomberg School of Public Health found that artificial infection with different Wolbachia strains can significantly reduce levels of the human malaria parasite, Plasmodium falciparum, in the mosquito, Anopheles gambiae. The investigators also determined that one of the...

Researchers at the Johns Hopkins Bloomberg School of Public Health have identified a bacterium in field-caught mosquitoes that, when present, stops the development of Plasmodium falciparum, the parasite that causes malaria in humans. According to the study, the Enterobacter bacterium is part of the naturally occurring microbial flora of the mosquito's gut and kills the parasite by producing reactive oxygen species (or free radical molecules). The study is published in the May 13 edition of...

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. The researchers found that after making specific genetic changes to a few mosquitoes, and then letting them breed, these genetic alterations could be spread through large mosquito populations in just a few generations. The system, known as a gene drive mechanism, was published online Wednesday...

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 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. In today's study, published in Nature, researchers have demonstrated how some genetic changes can be introduced into large...

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...
