A method for weekly production in excess of 100,000 second-instar larvae of the spruce budworm, Choristoneura fumiferana (Clem.), is described. It depends on adherence to specific regimes of physical conditions and manipulation for the different immature stages. Standard, easily obtained utensils and materials are used in the rearing technique.
