Zimmerman pine moth (Dioryctria zimmermani) is an insect pest. It was first detected in Missouri in 1984.

Zimmerman pine moth larvae mine inner barkand may also feed inside the terminal shoots. Mature larvae prepare their emergence sites by chewing away most of the bark from the inside. Damage ranges from branch dieback to death of major laterals or even the entire tree.
