Abstract

The biology and life history of the lodgepole terminal weevil, Pissodes terminalis was studied in the interior of British Columbia, Canada. Average longevity of females of P. terminalis was 112.8 days at 20°C. Mean lifetime fecundity was 115 eggs per female. The egg stage lasted 8 days, and pupation took 15 days. In the field, egg laying started at the beginning of June and all larvae reached the final instar by early September. Pupation began in mid-September and at the end of the month the first adult was ready to emerge.
