Caption: DDT insecticide research. Footage of research being carried out in the 1940s in a laboratory on the insecticide DDT (dichlorodiphenyltrichloroethane), which is being used for malaria control. First evaluated by the US Department of Agriculture in November 1942, DDT was found to be effective in small quantities when mixed as a concentrate with another powder, or mixed with fuel oil and spread over a large area. DDT affects the nervous systems and motor coordination of insects such as mosquitoes. Mosquitoes are the vector for malaria transmission. Preventing mosquitoes from breeding is one of the ways used to control the spread of malaria. One of the insecticides commonly used, until it was banned, was DDT. This footage is from a military training film produced in 1944 by the US Navy.
