Cherry Bark Tortrix
Enarmonia formosana (Scopoli)

Life Cycle: Overwinter as larvae under the bark on host trees. Older larvae pupate in spring. Moths are present from May to September. Eggs are laid mainly in bark crevices or under loose bark, especially near wounds, graft unions and pruning scars. Only one generation per year.

Monitoring: Pheromone lure is available to monitor male moths. Inspect trees for presence of gum-like resin mixed with excreta and silk on bark and pupation tubes protruding from feeding sites. Irregular tunnels under bark caused by larval feeding. Also look for cankers and conspicuous swellings on the trunk.

Hosts: Mature cherry, other stone fruits, apple, pear, quince, mountain ash.

Comments: Larvae resemble codling moth larvae in appearance and size.

Body length: Adult - 8.0mm; Mature larva - 11.0mm
