Pitch moth response to high dose phermone lures in Western Montana

Description:

Sequoi pitch moth, Synanthedon sequioiae, (SPM) and Douglas-fir pitch moth, Synanthedon novaroensis, (DFPM), both attack the boles and large branches of pine trees, especially those growing in tree improvement areas (TIA) and other trees growing off-site or that are stressed. They feed in the cambium of host trees causing large masses of pitch to form on the tree bole and can eventually cause branch and stem breakage.
