Researchers have discovered a way of reducing the fertility of malaria-carrying mosquitoes, potentially providing a new tactic to combat the disease. Anopheles gambiae mosquitoes are the main transmitters of malaria, which affects around 200 million people every year. The females mate only once during their lives. They store the sperm from this single mating in an organ called the spermatheca, from which they repeatedly take sperm over the course of their lifetime to fertilise the eggs that they lay.

In a study published in Nature Chemistry, they show that blocking the activity of an enzyme called NMT in the most common malaria parasite prevents mice from showing symptoms and extends their lifespan. The team are working to design molecules that target NMT more potently, and hope to start clinical trials of potential treatments within four years.

Every time a mosquito is lured to the scent of your skin, you're at risk of contracting malaria, dengue fever, West Nile virus, or another deadly disease. A study published by Cell Press December 5th in the journal Cell has revealed an important class of neurons responsible for a mosquito's attraction to human skin odor, as well as odors that stimulate and inhibit the activity of these neurons. The findings could lead to a new generation of repellants and traps for effective mosquito control worldwide.

Using advanced methodologies that pit drug compounds against specific types of malaria parasite cells, an international team of scientists, including researchers at the University of California, San Diego School of Medicine and the Genomics Institute of the Novartis Research Foundation, have identified a potential new weapon and approach for attacking the parasites that cause malaria.

An Ohio State University researcher and his collaborators have discovered a chemical that causes “kidney” failure in mosquitoes, which may pave the way to the development of new insecticides to fight deadly mosquito-transmitted diseases such as malaria and dengue fever.

Researchers at the Johns Hopkins Bloomberg School of Public Health have determined a new mechanism by which the mosquitoes’ immune system can respond with specificity to infections with various pathogens, including the parasite that causes malaria in humans, using one single gene. Unlike humans and other animals, insects do not make antibodies to target specific infections.
