Comparison of the Reproductive Potential of Anoplophora Glabripennis (motsch.) among Host Tree Species

Potential spread of the Asian longhorned beetle (Anoplophora glabripennis Motschulsky) (Coleoptera: Cerambycidae: Lamiinae: Lamiini) (ALB) in the United States is dependent upon its rates of reproduction and dispersal, particularly among host tree species that it encounters within suitable climatic regions. Therefore, the goal of this study was to measure the reproductive potential of ALB on three host tree species. More specifically, investigations of the age-specific fecundity and survivorship, and the intrinsic rate of increase of ALB were undertaken. This study of the individual performance of adult female ALB, which is under optimal conditions of the abiotic and biotic environment, represents the first of the three basic steps in the research approach in nutritional ecology outlined by Price (1997). The species of host-tree colonized obviously plays an important role in the reproductive success and population dynamics of ALB. Therefore, from among the tree species thus far reported attacked by ALB in the U.S., Norway maple (Acer platanoides L.), red maple (Acer rubrum L.) and black willow (Salix nigra Marsh.) were used. Norway maple is widely planted as an ornamental in urban landscapes, while red maple is prevalent among maple species in many northeastern U.S. forests. Willow is planted as an ornamental and is among the three most commonly attacked tree genera in China.
