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. |
