dichlorodiphenyltrichloroethane (DDT)Type: Term
1. An insecticide that came into prominence during and after World War II. For a time it proved effective, but insect populations rapidly developed tolerance for it, hence much of its original effectiveness has been lost; general usage is now widely discouraged because of the toxicity that results from the environmental persistence of this agent.
