dc.description	The larch casebearer Coleophora laricella (Hbn.) is now established throughout all western larch stands in Region 1. Population levels have begun to fluctuate in some of the older infested stands; however, it is still on the increase in more recently invaded territory. During the past 2 years work was begun to develop a method to forecast defoliation and tg ollow trends of the larch casebearer (Ciesla and Bousfield 1971).111/ The purpose of these evaluations was to establish the relationship between the overwintering population and subsequent defoliation for prediction purposes.
