Aspects of Hylotrupes bajulus (L.) biology in Virginia (Coleoptera: Cerambycidae)

The significant results of this research were: 1) A laboratory colony of H. bajulus was established and information on the N. A. biotype was collected. At this time it is too early to make any significant statements of comparison between European and N. A. biotypes. However, preliminary results indicate that the mean number of eggs per female, and the size and longevity of N. A. adults appear different than European beetles; 2) Outdoor survival studies of the larvae indicate that H. bajulus can live under natural conditions in Virginia's varied climatic regions. Over the course of two years 27 adults have been collected in such field conditions as fence posts, outhouses, screen windows, building exteriors, and free flying in open fields. This information, along with survival studies, strongly suggest the presence of natural populations; 3) The environment in which H bajulus larvae are located greatly affects its chances of survival. Larvae in attics can survive the fluctuating environmental condition, but growth and development are prolonged and potential structural damage minimal. Under these conditions H. bajulus larvae are more likely to undergo natural mortality over several years. In optimum (stable) conditions H. bajulus will increase their feeding and development. Under these conditions infestations that are left unchecked may lead to serious structural damage and reinfestations.
