Spruce Rust Mites remain active on Spruce in Westmoreland County

Hemlock Rust Mites have hatched and adults are active in Westmoreland and Allegheny Counties at this time.

Overwintering Cooley Spruce Gall Adelgids observed this week on Douglas-fir in Westmoreland County showed little change from the previous week. Control measures can still be applied at this time when the temperature permits.

Nurseries or landscapes with a previous history of White Pine Weevil problems should be scouting at this time for evidence of adult feeding on the terminals of Eastern White Pine, Norway Spruce, Oriental Spruce, and Colorado Blue Spruce.

The next scouting report will be on Friday, March 29.
