Extract

Except for occasional references in the Annual Reports of the Forest Insect and Disease Survey of infestations of an aphid on caragana (Caragana arborescens Lam.) in Western Canada and a note on chemical control (Bradley, 1952), there is no published record known to the authors of the occurrence of the caragana aphid, Acyrthosiphon caraganae (Cholod.), in North America. MacNay (1953) summarized reports that severe infesrations of aphids, “probably mainly the caragana aphid”, occurred on caragana in 1952 in the East Kootenays of British Columbia, and at several places in Alberta and Saskatchewan. At some localities 100 per cent defoliation was reported.
