Cases of dengue were greatly reduced in areas of a city where Wolbachia-infected mosquitos were released, according to preliminary data from a field study.

Unable to travel to international or remote sites, some researchers are losing critical data.

Aedes aegypti infected with Wolbachia—which inhibit transmission of the dengue virus from insect to human—were deployed in Indonesia, Vietnam, Brazil, and Australia.

Researchers use two techniques—Wolbachia infection and irradiation—to suppress reproduction in populations of Asian tiger mosquitoes at two study sites in China.

Researchers can now track the expansion of a resistance mechanism that allows the malaria vector Anopholes funestus to detoxify a key insecticide used on bed nets.

The parasite that causes malaria has evolved to evade many of the drugs that researchers have developed to fight the tropical disease.
