Abstract

Insects cause considerable seed loss in cones of grand fir, <i>Abies grandis</i> (Doug.) Lindl. on Vancouver Island. Three species of midge, a scale feeder, a gall former, and a seed-feeding midge; two species of seed chalcid, <i>Megastigmus pinus</i> Parf. and <i>M. rafni</i> Hoff.; and a cone maggot, <i>Earomyia abietum</i> McAlpine, were responsible for most of the damage. Coneworms were not important.
