    Ovariole development and termination of diapause in adult white-pine weevils, Pissodes strobi (Peck), of known age were studied by dissection and photographically recorded. Old-generation adults brought into the laboratory in early November produced viable eggs within 5 days. New-generation adults brought into the laboratory during this same period also produced viable eggs. Viable eggs were deposited by other new-generation adults after 10-15 clays at room temperature in winter. On each of the 3 collection dates studied, a new-generation adult produced viable eggs without copulating after collection from hibernation, indicating that copulation occurred in the fall. New-generation adults which were isolated as soon as they emerged in July and August and maintained at 75°±1O°F had poorly developed ovarioles by November 20 and did not produce eggs. These observations confirm reports that diapause is obligatory in the white-pine weevil, but indicate that the temperature requirement for breaking diapause is satisfied by early November.
