Abstract
Incidental to some toxicological studies reported elsewhere (Middlekauff & Hansberry, 1941) there was an excellent opportunity to make interesting notes on the biology of the adults of the apple maggot, Rhagoletis pomonella (Walsh), and the cherry fruitflies, Rhagoletis fausta (O. S.), and Rhagoletis cingulata (Loew).
