THE GREAT MOSQUITO HUNT

Abstract

Among those refusing to give up is Tovi Lehmann, a research entomologist at the US National Institute of Health's Laboratory of Malaria and Vector Research in Rockville, Maryland, who, along with dozens of team members in both the United States and Africa, has spent six years and about US$700,000 trying to find the elusive insects with every method he can think of, including dogs such as Dana. Studies in the 1940s, for instance, tried to replicate natural conditions in the lab but failed to get female mosquitoes to go dormant, according to Douglas Norris, a medical entomologist at the Johns Hopkins Bloomberg School of Public Health in Baltimore, Maryland.
