A U.S.-led study suggests insecticides that would kill just older mosquitoes would be a better way of controlling malaria. Pennsylvania State University Professor Andrew Read said such an approach would be a more sustainable way of controlling the disease and might lead to evolution-proof insecticides that never become obsolete. Each year malaria kills about a million people, but many of the chemicals used to kill the insects become ineffective, the scientists said, since repeated exposure to...

Killing just the older mosquitoes would be a more sustainable way of controlling malaria, according to entomologists who add that the approach may lead to evolution-proof insecticides that never become obsolete.Each year malaria -- spread through mosquito bites -- kills about a million people, but many of the chemicals used to kill the insects become ineffective. Repeated exposure to an insecticide breeds a new generation of mosquitoes that are resistant to that particular...

Targeting mosquito larval populations may be an effective intervention to help control malaria in urban situations, a study published yesterday suggests. The research, conducted in Dar es Salaam, the largest city in Tanzania, has re-opened the debate on whether malaria can be controlled with larvicides, insecticides which kill mosquitoes in their water-borne larval stages of development. Malaria is one of the world's deadliest diseases, killing over one million people each year, mainly young...

Researchers at the Johns Hopkins Bloomberg School of Public Health have for the first time identified a molecular pathway that triggers an immune response in multiple mosquito species capable of stopping the development of Plasmodium falciparum"”the parasite that causes malaria in humans. By silencing the gene, caspar, the researchers were able to block the development of the malaria-causing parasite in Anopheles gambiae, A. stephensi and A. albimanus mosquitoes"”three mosquito...

Temperature is an important factor in the spread of malaria and other mosquito-borne diseases, but researchers who look at average monthly or annual temperatures are not seeing the whole picture. Global climate change will affect daily temperature variations, which can have a more pronounced effect on parasite development, according to a Penn State entomologist. "We need higher resolution environmental and biological data to understand how climate change will affect the spread of the malaria...

Isolongifolenone found as effective as DEET against mosquitoes and ticksIsolongifolenone, a natural compound found in the Tauroniro tree (Humiria balsamifera) of South America, has been found to effectively deter biting of mosquitoes and to repel ticks, both of which are known spreaders of diseases such as malaria, West Nile virus, and Lyme disease.  Derivatives of isolongifolenone have been widely and safely used as fragrances in cosmetics, perfumes, deodorants, and paper products, and...

Hundreds of millions of anti-malaria kits and mosquito nets will be distributed by 2010 as part of a campaign to stop one million annual malaria deaths, officials organizing the initiative said Saturday. They called on donors not to abandon the program because of the global economic crisis, and emphasized that there was significant possibility the malaria epidemic could be wiped out in the coming years. "The resources to attack this problem -- to eliminate malaria deaths -- is there. We can...

Researchers have identified a gene in mosquitoes that helps the insects to fight off infection by the Plasmodium parasite, which causes malaria in humans. Anopheles mosquitoes transmit the malaria parasite to nearly 550 million people worldwide each year with these cases resulting in more than 2 million deaths annually. The protective gene was identified in a study conducted by a team of investigators from the Johns Hopkins Bloomberg School of Public Health\'s Malaria Research Institute, the...

Malaria remains a devastating problem in Africa and understanding the factors affecting its transmission remains a crucial part of the effort to combat the disease. A new study published in the premier open access journal PLoS Biology conducted in Western Kenya by Jacob Koella and colleagues now reveals that mosquitoes are more attracted to children with the infectious stages of malaria than to those infected with non-transmissible forms of the disease or to uninfected people. The question...

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...
