Abstract

Western spruce budworm were reared on three host foliages and artificial medium. Trace element analyses showed large differences in elemental concentrations between food sources and only minor differences between insect life stages. Discriminant analyses were carried out to test the distinctiveness of adult chemoprints from each rearing regime. Fe, Cu, and Zn were distributed differentially between egg mass and other parts of the female moths. Females reared on artificial medium weighed more than foliage-fed females.
