Abstract
Studies of the life history of Bradysia impatiens (Johannsen), reared on ground soybeans, were conducted in the laboratory. The egg, 4 larval instars, pupa, and adult are described and measurements are given. Preoviposition period was less than 24 hr when males were present. Fecundity ranged from 12 to 156 eggs, and averaged about 75 eggs per female at 75°F. The mean periods of incubation, development, and longevity were: egg, 4.0; larva I, 3.3; larva II, 3.1; larva III, 1.8 larva IV, 5.9; pupa, 3.5; and adult, 5.9 days. The anatomy of the larval head capsule and male terminalia is given, and the male terminalia are figured. Various aspects of adult and larval behavior are described.Keywords
