Extract

During 1950 and 1951 the writer collaborated with officers of the Commonwealth Institute of Biological Control in studies of the predators of Adelges (Dreyfusia) piceae (Ratz.) and Adelges (Dreyfusia) nüsslini (Börner) in Europe. These studies preceded the importation of the more important predacious species into Canada and their release against A. piceae. Observations on one of these predators, Aphidecta obliterata (L.) (Coleoptera: Coccinellidae), are given in this paper.
