Excerpt from Larch Sawfly Conditions in the Lake States in 1954: A Reconnaissance Survey The extent and severity of the infestation in the Lake States in 1954 was determined by reconnaissance surveys similar to those made in 1953. In the northern half of Minnesota, an aerial survey was made to determine the areas of partial and complete defoliation. An intensive ground reconnaissance was also conducted in observation points established in 1951; data were taken on the amount of defoliation of individual trees, and cocoons were collected for research purposes. Because of the limited time available, only restricted ground observations were made in Michigan and Wisconsin where infestations are relatively light.
