Codling moth larva and feeding damage |
Life Cycle: Overwinter on trees as mature larvae in cocoons. First brood adults appear early May/June; first brood larvae June/early July; second brood adults mid-July/early August; second brood larvae Augst; third generation possible late August/early September.
Monitoring: Use phermone traps to set biofix and start degree-day accumulation to time first spray. Use the traps to monitor presence and abundance of male moths througout the season. Examine fruit for larval entries (stings) into fruit.
Hosts: Apple, crabapple, pear, soft fruits, walnut, quince.
Comments: The copper spot on the forewings distinguishes male codling moths from other small moths found in pheromone traps. Mature larvae are dirty white or pinkish with a mottled brown head while young larvae have black heads. Codler larvae closely resemble oriental fruit moth larvae which have not yet been found in B.C.
Body length: Adult - 9.0mm; Mature larva - 15.0mm
