THE AMOUNT OF FOLIAGE CONSUMED OR DESTROYED BY LABORATORY-REARED LARVAE OF THE BLACK-HEADED BUDWORM, ACLERIS VARIANA
Published online by Cambridge University Press: 31 May 2012
Abstract
Sitka spruce produces twice as many needles per linear inch of twig as western hemlock. Defoliation by the black-headed budworm, Acleris variana (Fern.), is more severe on hemlock than spruce because of differences in the phenological development of the hosts and in the feeding behavior of first- and second-instar larvae on each of the hosts.
