Spruce budworm

White spruce stands that have experienced spruce budworm defoliations during the past eight to ten years in Region 1 did not have larval defoliations in 2002 except for two sites:

  1. a site in Sec. 21-141-36, Osage Twp. in Becker County. Surveys were taken after larval stages were completed but pupae, along with pupal cases were observed along with an average of 15% defoliation of new shoots, and
  2. a site in Itasca State Park along Wilderness Drive in Sec. 16-143-36 experienced moderate to heavy defoliation this spring.

This is the fourth year of defoliation on this site.
