A Synthetic Diet for the Spruce Budworm, Choristoneura fumiferana (Clem.) (Lepidoptera: Tortricidae)

Abstract

The spruce budworm, Choristoneura fumiferana (Clemens), was reared on a synthetic diet. Comparison of two successive laboratory generations reared on synthetic diet and on frozen balsam fir buds showed that diet-fed insects had a higher survival, developed faster, were heavier, mated more successfully, and were more fecund.
