Ornamental Cherry: Shothole borer
revision date: 2022-11-26 09:49
Shothole borer larvae feed between the bark and the wood on the limbs and trunks of cherry trees. The white larvae (bark beetles) are about 1/8″ long and feed in galleries made beneath the bark parallel to the grain of the wood. The adults emerge from the trees, leaving numerous small holes about the diameter of a pencil lead in the bark. Adult beetles are black with cinnamon-colored antennae and legs. They are about 1/8″ long or less. Shothole borers may bore into the buds of healthy trees, but are primarily attracted to unhealthy trees. Sunscald damage to trunks during winter serves as a common entry point for these beetles.
Use Integrated Pest Management (IPM) for successful plant problem management.
Select non-chemical management options as your first choice!
- Provide proper plant culture to maintain health and increase resistance to shothole borer attack.
- Prune out all dead and dying branches.
- Burn, chip, or otherwise destroy all infested or suspicious prunings to prevent emergence of adults.
- Remove dead or dying trees from the landscape.
- Whitewashing trunks or applying commercial white trunk bands helps prevent sunscald and borer infestations.
