Abstract

Eucosma rescissoriana Heinrich is highly destructive to cones and seed of western white pine, Pinus monticola Douglas, and is distributed throughout the geographic range of this host species in northern Idaho. One generation is passed per year with emergence in late May. Egg and larval stages arc generally found in June and July; the pupal stage overwinters. Stand density and elevation were used as variables in ecological studies of population sine. All stages of E. rescissoriana were correlated to phenological data in 1962.
