THE OCCURRENCE OF TWO SPECIES OF CECIDOMYIDS ON MEADOW FOXTAIL (ALOPECURUS PRATENSIS L.) HITHERTO UNREPORTED IN CANADA

Abstract

For the purpose of determining whether foxtail midges occurred in Canada and if so their range, a survey of places where meadow foxtail grass, Alope curus pratensis L. was known to be grown was made in the spring of 1934. This survey followed a request for information upon the point by Dr. L. E. Kirk, Dominion Agrostologist, on behalf of Dr. R. O. Whyte, Chief Officer of the Imperial Bureau of Plant Genetics; Herbage Plants, Aberystwyth, Great Britain. Dr. Whyte is interested in discovering areas free from foxtail midges which might bme used for the production of meadow foxtail seed. The location of stands of the grass were secured through Dr. Kirk and co-operation in making observations was sought and readily obtained from various people living in the vicinity of these stands in Canada.
