What's eating my mexican pinyon?

Mexican Pinyon shares the same key threats as other pinyon pines: Ips bark beetles kill stressed trees, while pinyon jays and squirrels consume most of the seed crop. Pinyon pitch nodule moth damages shoots. In cultivation, watch for pine needle scale on foliage. Drought stress dramatically worsens beetle susceptibility.

Pitch tubes, boring dust, and reddish frass on bark; galleries under bark kill cambium; rapid whole-tree death Avoid drought stress; remove infested wood quickly; preventive bark sprays (permethrin) in high-pressure areas; do not store fresh-cut pine logs near trees

Resin nodules (pitch masses) at growing shoot tips; stunted or killed new shoots Prune and destroy infested shoot tips in late winter before adult emergence; no chemical control typically needed

Cones cut from branches and cached; significant loss of seed crop before harvest Hardware cloth tree guards on young trunks; harvest cones as soon as seeds are mature and firm
