Survival, Development Time, and Pupal Weights of Larvae of Gypsy Moth Reared on Foliage of Common Trees of the Upper Great Lakes Region
Survival, development time, and pupal weights of larvae were determined for gypsy moth reared on foliage of red oak, sugar maple, white birch, trembling aspen, white spruce, black spruce, jack pine, and balsam fir. Mortality was >50% on sugar maple and balsam fir, 35% on jack pine, and ≤15% on the other species. Female larvae developed significantly faster on trembling aspen foliage (29 days at 21°C) than on that of other species. Larvae reared on foliage of trembling aspen, white birch, or a mixture of foliage of either species and that of other species produced larger pupae than did other foliage combinations. North. J. Appl. For. 8(3):126-128.
