Extract

During the course of genetic studies on the spruce and jack pine budworms, it was noted that there are distinct morphological characters on which the pupae and egg clusters may be separated. They are described here as a contribution towards the taxonomic separation of Choristoneura fumiferana (Clem.) and C. pinus Free.
