Abstract

Anoplophora glabripennis Motschulsky (Coleoptera: Cerambycidae) is an invasive wood-boring beetle that primarily infests Acer rubrum L. (Sapindales: Sapindaceae) in North America. The first signs of infestation in a host tree are oviposition pits indicating female beetles have attempted to place eggs in the phloem; however, the presence of oviposition pits does not always guarantee the presence and survival of eggs or larvae, and little is known about the relative success of beetle oviposition. To better understand A. glabripennis oviposition and early larval survival, we infested A. rubrum in a common garden environment. We conducted daily observations and destructively harvested these trees to analyze oviposition pit occupation, egg viability, and early larval survival, and compared patterns of oviposition success and survival with field-collected material from naturally infested host trees in the surrounding environment. Oviposition pits on field-collected material were also examined to explore potential links between host tree characteristics and A. glabripennis oviposition success. Our results support previous findings that fecundity is highly variable among individuals, that A. glabripennis oviposition pits were most commonly observed on host material with intermediate sized diameters (6 to 15 cm) and textured bark, and oviposition pits were often chewed without depositing an egg. Oviposition pit occupation, egg viability, and early larval survival were significantly lower on host trees in the common garden environment relative to naturally infested field material. Understanding oviposition and early survival and how host tree characteristics can impact fecundity can help improve detection and more efficiently utilize resources dedicated to invasive species management.
