Description
Summary:Abstract The leaf tier or webworm, Cnephasia virgaureana Treit., was first reported in Newfoundland in 1916, but no further records were noted from that area until 1957 when it was found causing severe damage to certain crops. An infestation of this webworm was discovered in Prince Edward Island in 1955, and severe infestations were reported in areas of Bavaria and Boden, Germany, in 1954. It was assumed that importations of the pest must have been made into Canada about 1954 or 1955. The life history of the pest is discussed and the parasites found during the period of study are listed.
