Shipments of fresh fruit from the Maritimes to Newfoundland and British Columbia are prohibited. Shipments to all other noninfested areas in Canada must be inspected and certified to be maggot-free. The adults emerge from late June to late August. Their numbers peak during the second and third weeks of July. Egg laying begins 7-10 days after emergence with peak numbers occurring during the third and fourth week of July.
Most pupae develop and emerge into adults in the following year.
However, a few remain and do not develop into adults until the second or third year. The adults prefer areas with a plentiful supply of berries that are sheltered from prevailing winds by woods, weeds, hollows, rocky outcrops, or rock walls. As a result, their distribution and that of infested fruit is often uneven, unless populations are at extremely high levels. Yellow, rectangular, sticky traps are very attractive to the adults and when displayed in the preferred sites will detect the adults at very low population levels. Their use monitors adult activity to determine the need and timing for control treatments.
