The European pine sawfly, Neodiprion sertifer (Geoffroy), is a perennial problem in young pine plantations in Eastern North America. Scotch pine, Pinus sylvestris L., and red pine, P. resinom Ait., are its principal hosts. During recent behavioral studies of this sawfly in Michigan, spatial distribution patterns were determined in order to rapidly survey population levels in young pine plantations (Wilson and Gerrard, 1971). Earlier, Lyons (1964b) presented some distributional data on N. sertifer in regard to population sampling. Wright et al. (1967) and Hattemer et al. (1969) discussed N. sertifer distributions in Scotch pine and mixed pine species provenancz plantings.
