Extract

Ocnerostoma piniariella Zell. is an unimportant pest of Scots pine, Pinus sylvestris L., in Europe. A variety, copiosella Frey, is found in the Swiss Alps attacking a white pine, Pinus cembra L., and sometimes occurs in sufficient numbers to reduce growth. Both European forms have a life-history similar to that described here for British Columbia.

In North America, specimens identified as O. piniariella were collected in 1882 at Ithaca, New York (Forbes, 1924). The first Canadian record was for 1922 at Abbotsford, British Columbia, from white pine (Felt, 1922). The species has since been found in British Columbia at Vancouver, Victoria, Langley, and Aldergrove. Dr. T. N. Freeman (in litt.), Entomology Division, Ottawa, has collected it at Constance Bay, South March, Ottawa, and Bells Corners, Ontario.
