Three generations of Grapholitha molesta (Busck) have been completed and a growing laboratory colony has been established on the following artificial larval diet as such or slightly modified: tap water 75, potassium sorbate 0.1, methyl p-hydroxybenzoate 0.15, agar 3, alfalfa leaf meal 5, carrot baby food 10, vitaminized apple juice 10, casein 0.5, roasted peanuts 2, soy hydrolyzate 0.5, brewer's yeast, 6, yeast extract 2, and salt mixture 0.5, with or without vitamin solution 0.5, and ascorbic acid 0.5 parts by weight. Data from 1 generation only suggest that several other simpler diets may also be suitable. The right kind of yeast, covering the surface of the diet with wax, and puncturing or scoring the surface were important for a satisfactory yield.
