Extract

The woolly pine needle aphid, Schizolachnus pini-radiatae, was described in 1909 by Davidson as Lachnus pini-radiatae from specimens collected near Stanford University, California. In revising the subtribe Cinarina, Gillette and Palmer (1931) placed this species in the genus Schizolachnus. Detailed descriptions of the species were given by Davidson (1909), Gillette and Palmer (1931), and Palmer (1952), but none of the earlier workers studied the life history of this aphid. The present study was carried out during 1960 in a seven-year-oId red pine stand in kirkwood Township, about 50 miles east of Sault Ste. Marie, Ontario.
