Abstract
Egg bands of the forest tent caterpillar, Malacosoma disstria Hübner, were sampled across a wide area of the Canadian prairie provinces during a large-scale outbreak in 1989 and 1990 to examine the incidence and distribution of egg parasitoids (Hymenoptera). Data on the parasitoid species found and the incidence and frequency of parasitism in three habitat types is presented. Three species of egg parasitoids were recovered, Telenomus clisiocampae Riley (Scelionidae), Ooencyrtus clisiocampae (Ashmead) (Encyrtidae), and Baryscapus malacosomae (Girault) (Eulophidae). Differences in the number of species occurring per egg band and the percent of parasitism were found among habitat types. These differences are correlated to the amount of spumaline cover on egg bands, which also varied among habitat types.
期刊介绍：
French translation follows/le français suit Published since 1868, this peer-reviewed bimonthly publication is the official journal of the Entomological Society of Canada. Available via the internet and with hardcopy distribution to 55 countries, its research papers and notes are relevant to entomologists and other biologists around the world. In addition to being a venue for topical reviews and forum discussion, The Canadian Entomologist publishes current research in all facets of entomology, including systematics and morphology, molecular and developmental biology, ecology and behaviour, biodiversity and evolution, insect management, entomological techniques, and other relevant subject areas. Contributions are published in English or French. Authors will not pay page charges, and will experience fast, high quality reviews of their papers.Publiée depuis 1868, cette publication bimestrielle avec comité de lecture est la revue officielle de la Société d’entomologie du Canada. Disponible sur Internet et distribuée en format papier dans 55 pays, ses articles de recherche et ses notes sont pertinents pour les entomologistes et autres biologistes de par le monde. En plus d’être une plate-forme pour des revues thématiques et un forum de discussion, The Canadian Entomologist publie la recherche actuelle sur toutes les facettes de l’entomologie, incluant la systématique et la morphologie, la biologie moléculaire et développementale, l’écologie et le comportement, la biodiversité et l’évolution, la gestion des insectes, les techniques entomologiques et d’autres domaines pertinents. Les contributions sont publiées en français ou en anglais. Les auteurs ne paient aucun frais de publication, et recevront une révision rapide et de grande qualité de leurs articles.
