Adults obtained from larvae of the yellow-fever mosquito, Aedes aegypti (L.), treated with dilute solutions of a tranquilizer, trifluoperazine dihydrochloride (2 to 75 ppm), indicate that the chemical has teratogenic effects on the insect. Some of the ensuing adults showed morphological abnormalities similar to those of recognized mutants which have been found in nature or produced as a result of thermal stress in the laboratory. In others, some of the head structures were either deformed or fused, and the normal functioning of the mouthparts became impossible. At the highest concentration tested (75 ppm) the eclosion of the imagoes was also affected. It is suggested that chemicals having similar properties, which are per se nontoxic, can be used effectively for the regulation of insect populations.
