Atlas of aphids trapped in agricultural crops / by Lola L. Gualtieri and D. G. R. McLeod, Research Centre, London, Ontario. Issued by the Research Branch. Ottawa : Agriculture and Agri-Food Canada. 1994. vi, 66p. : figs. ; 28 cm. "This atlas is not meant to be a definitive work on aphids in Canada, but rather a tool to be used by crop protection specialists to help them identify and separate pest species from other species not harmful to agricultural crops, or at least only incidentally present. Species are identified by visually comparing captured aphid specimens with pictures of the whole aphid and with pictures of organs or appendages that are important for identification. It should be noted that only the alate female form was used for this atlas. A total of 60 aphid species are included in the atlas. Most aphids were trapped near London, Ontario, over a period of 7 years."--Preface. Bibliography. Identify 60 of the most common destructive aphids quickly and easily by comparing captured aphid specimens with more than 250 photographs. Includes brief descriptions, alphabetical listing of species, common names and a comprehensive glossary. Softcover 94-18 1994-05-06 Crops gcpds Insects gcpds McLeod, D. G. R.
