Abstract

The pitted ambrosia beetle, Corthylus punctatissimus (Zimm.), was studied during widespread infestations in sugar maple (Acer saccharum Marsh.) stands of southern Ontario and Quebec. A brief description of each stage of the insect is given, and its life history and habits, as well as the damage caused to the host plant are discussed.

Résumé

L’auteur a observé le Corthyle de l'érable (Corthylus punctatissimus (Zimm.)) qui infestait sur de grandes étendues les peuplements d'Érable à sucre (Acer saccharum Marsh.) situés dans les secteurs sud de l'Ontario et du Québec. Il décrit sommairement chacune des formes de l'insecte et traite de son cycle évolutif annuel, de ses habitudes et de l'étendue des dommages causés.
