AbstractNine species of parasites and one hyperparasite were reared from a complex of the brace spanworm, Operophtera bruceata (Hulst), and the European winter moth, O. brumata (L.), collected in the Victoria area of Vancouver Island, British Columbia, in 1976 and 1977. Parasitism of the host complex was about 1.5%, mainly due to an unnamed species of Phobocampe (Ichneumonidae). All species of parasites taken in British Columbia on the two hosts have congeneric counterparts on O. brumata in Europe as listed by Wylie (1961); thus the release of exotic species in addition to the two already released in British Columbia may not enhance the biological control of O. brumata. Descriptions and illustrations of cephalic structures of final-instar larvae of the parasites and a key for their separation are given.

An expanding outbreak of hardwood-defoliating geometrid larvae (Lepidoptera: Geometridae) has existed on southern Vancouver Island, B.C., since at least 1972. By 1977 the outbreak had become severe over an estimated 120 km2 in the Victoria and Saanich land districts and a light infestation was present on the Saanich Peninsula.

AbstractThree native species of parasites and 3 hyperparasites were reared from pupae of the European winter moth, Operophtera brumata (L.), and the Bruce spanworm, O. bruceata (Hulst), collected in the Victoria area of Vancouver Island, British Columbia, in 1981. Two of the pupal parasites also attacked other species of Geometridae. Two species of hyperparasites attacked Cyzenis sp., and the third parasitized ichneumonid primary parasites of Operophtera spp. The hyperparasites may have a negative impact on the biological-control agents, Cyzenis albicans (Fall.) and Agrypon flaveolatum (Grav.). Total parasitism by pupal parasites of the Operophtera host complex was about 4%. Descriptions and illustrations of cephalic structures of final-instar larvae of the parasites and a key for their separation are given.

Thirty-one species of eutardigrades were collected on five mountains on Vancouver Island, British Columbia, during July 1986 and July 1987. Three of the species found were new to science, including 1 species, Platicrista cheleusis n.sp., described herein and 2 species described elsewhere, and 21 others are new to British Columbia; 13 of these are also new to Canada.
