Abstract
The spruce coneworm, Dioryctria reniculleloides (Mut. and Mun.), is often associated with the spruce budworm on spruce host trees and sometimes approaches or equals the spruce budworm, Choristoneura fumiferana (Clem.), in numbers (Spies and Dimond 1985). The coneworn is probably~responsiblefo r some of the damage on spruce attributed to the budworm, and with much balsam fir in eastern North America now dead from defoliation or harvested, there is increasing interest in spruce as the major resource to protect.Keywords
