When larvae of Tribolium castaneum were reared on diets deficient in thiamine, pyridoxine or riboflavin mortality was high and the rate of development was slow. The few surviving larvae did attain the same final stage as larvae developing on an all-vitamin control. On diets deficient in nicotinic acid, calcium pantothenate or choline chloride all aspects of development were impaired and no pupation occurred. The negative effects of folic acid deficiency were more pronounced in the pupal stage than in the larval instars. The dietary deficiency of folic acid, choline chloride or thiamine, had no apparent effect on adult fecundity, and a dietary deficiency of any one of the seven vitamins assayed did not adversely affect egg fertility.
