Two artificial media were used to determine some nutritional requirements for development of newly hatched larvae of Scolytus multistriatus (Marsham) into adults. Under the test conditions, the larvae required a sterol, inositol, and potassium to become adults. Cholesterol, cholesterol acetate, sitosterol, stigmasterol, and ergosterol were utilized; but cholestanol and not. Deletion from the media of choline and any of the B-vitamins, except riboflavin. greatly reduced adult emergence when the test larvae were obtained from eggs dissected from elm wood. When the test larvae hatched from eggs from artificial media, none survived on media lacking niacin amide, calcium pantothenate, riboflavin, pyridoxin, or folic acid. Deletion of biotin signiticantly reduced adult emergence. Larval survival on biotin-deficient media increased after 1 mg of biotin had been added to the oviposition medium of their parents.
