Abstract

Emergence patterns of terminal weevils (Coleoptera: Curculionidae) and their parasitoids from lodgepole pine in the Interior of British Columbia, Canada.

Abstract

Pissodes terminalis, Magdalis gentilis and Cylindrocopturus sp. emerged from dead leaders collected from lodgepole pine (Pinus contorta) between 7 and 11 May 1987 at 2 sites in British Columbia. M. gentilis began to emerge at the beginning of May, while Pissodes terminalis and Cylindrocopturus sp. emerged a month later. Parasitoids reared from infested terminals belonged to 9 species in 6 families. The most important species was the pteromalid Rhopalichus pulchripennis, followed by 2 species of the genus Eurytoma. The emergence of the majority of parasitoids preceded that of P. terminalis and Cylindrocopturus sp.
