Suitability of Acer saccharum and Acer pensylvanicum (Aceraceae) for rearing Anoplophora glabripennis (Coleoptera: Cerambycidae)

摘要

Striped maple (Acer pensylvanicum L.) was compared with sugar maple (Acer saccharum Marsh.) for use in rearing Asian longhorned beetles (Anoplophora glabripennis (Motschulsky)). Adult females lived longer when caged with twigs and small bolts harvested from A. pensylvanicum during late spring through early fall than with material from A. saccharum collected at the same time. Females had a shorter life-span when fed plant material from either tree species harvested from late fall through winter than with plant material from A. pensylvanicum harvested from late spring through early fall. Female A. glabripennis laid more viable eggs when provided with A. pensylvanicum rather than A. saccharum. Regardless of which of these two tree species females had experienced previously, they always chose to lay more eggs in A. pensylvanicum than in A. saccharum. Rearing A. glabripennis on A. pensylvanicum is therefore more efficient, especially when twigs and wood collected from late spring through early fall areused.
