Abstract
The white pine sawfly, Neodiprion pirletunl. is monophagous on eastern white pine, Pinus strobus, throughout its range in eastern North America. Localized outbreaks occur frequently, and small areas of white pine may be killed. The high population upsurge in Crawford County. Wisconsin, in 1978 was mitigated by the eulophid egg parasite, Closterocerus cinctipennis, when a mean 90.1 t 4.870 parasitization occurred. Larval parasitization in the Grant County infestation averaged 45.05%. and involved the ichneumonid, Olesicampe lophyri, the perilampid Perilamplts l~yalirllcs, and the tachinid Spathimeigenia erecta.
