An inventory was taken of aphid species occurring on balsam fir, white spruce, larch, red pine, white pine, jack pine, and black spruce at two sites where the introduced red wood and, Formica lugubris Zett., had been released. Twenty-one aphid species were found, all in the gens Cinara Curtis. Nine of these species, and possibly a tenth, were new records for Quebec. Observations on colony size and distribution on host trees, in ant infested and control blocks, were recorded.
