Abstract:

Southern pine beetle, Dendrotonus frontalis Zimm., infestations were endemic on 480,000 of national forest in central Louisiana for 3 years from July 1977 through June 1980. Study of 137 spots that varied in size from 3 to 57 trees showed that spots of less than 10 trees were in large-diameter stands, that large sawtimber comprised 80% of the infested volume per acre, and that the cumulative losses of large sawtimber were almost 9 times the losses in 30- to 57-tree spots. Based on these results, small spots in sawtimber stands should receive as high, or higher, control priority as large spots in small diameter stands during endemic periods.ยน
