DIFFERENCES IN THE LIFE HISTORY OF CODLING MOTH, CARPOCAPSA POMONELLA (L.), ATTACKING PEAR AND APPLE

Abstract

For several years experiments on codling moth control have been carried on in a large old pear orchard near Beamsville in the Niagara Peninsula, Ontario. This orchard comprises about nine acres of several varieties but predominantly Bartlett, and has been established for about 80 years. It is more or less isolated from other large pear or apple orchards.
