Growth of Heliothis virescens (F.) when fed on sterile wheat germ diets was the same when ascorbic acid was added to diets before the diet was autoclaved or after the diet was autoclaved and cooled. Adults developed from both diets, but growth was poor in diet lacking ascorbic acid and no adults were obtained, thus proving that this insect has a dietary need for the vitamin. Analysis of the diets for ascorbic acid by the 2,6- dichloroindophenol method showed that no loss occurred in either heating method.
