Downloadable ContentDownload PDF
An infestation of a defoliating weevil, Magdalis gentilis LeConte, was reported in July by Hank Manning, Judith Ranger District forester, Lewis and Clark National Forest. The infestation occurs in precommercially thinned stands of lodgepole pine, Pinus contorta var./atifblia Engelm. in the Moose Creek drainage. Although damages caused by M. gentilis are relatively uncommon in Region 1 forests, the current problem has existed since 1965 (Fellin 1973). An evaluation of the infestation was made August 14, 1974.
