Extract

On October 16, 1956, during a routine monthly check of the Nurses Residence, Selkirk Mental Hospital, Selkirk, Manitoba, a professional exterminator noticed “thousands” of very small insects in a basement office. A number were submitted to the writer for identification and found to be aphids, which were later very kindly identified by W. R. Richards, Insect Systematics and Biological Control Unit, Ottawa, as Sipha agropyrella (H.R.L.). Richards stated (in litt.): “This is the first record of this species west of Ontario.” MacGillivray (1956) records the finding of this species in 1950 in New Brunswick as a new record for North America.
