Six orchards in the Okanagan and Similkameen Valleys of British Columbia, were monitored with traps baited with Codlemone ® , a sex attractant of Laspeyresia pomonella (L.). Sprays were applied only if (1) traps within the orchard captured two or more moths per trap per week and if entires were found in the fruit; or (2) border traps captured more than two moths per trap per week and infested apples were found. Using these criteria, one spray was sufficient in one orchard and two were sufficient in three orchards, instead of the three sprays usually applied. A normal spray program was followed in the remaining two orchards.
