Extract

No research has previously been conducted on gall aphids on poplar in Alberta. Strickland (1953) published records of some of these aphids in his list of Hemiptera of Alberta. Manson (1931) mentioned that noctuids fed in galls of Pemphigus populitransversus Riley.

In the United States, several workers have reported on these aphids. Palmcr (1952, pp. 358-372) published a key to and some bioiogical notes on several species of the genus Pemphigus and related genera. Maxson and Knowlton (1929) gave considerable information on the life-history and classification of the tribe Pemphigini. Maxson (1923) and Hottes and Frison (1931) published keys to the same tribe. Essig (1926, pp. 259-261), Gillette (1913). Gillette and Bragg (1915), Jackson (1908), Oestlund and Hottes (1926), Patch (1913), Swaine (1919), and Williams (1910) also reported on some of the gall aphids on poplar.
