A Method of Rearing Bark- and Cambium-Feeding Beetles with particular Reference to Hylobius warreni Wood (Coleoptera: Curculionidae)

Abstract

Hylobius warreni Wood is a recently described weevil that was originally confused with Hypomolyx piceus (DeGeer, 1957). The larvae attack the inner bark and cambium of the root system of jack pine, Pinus bankisiana Lamb., and other conifers (Warren, 1956). The life history of this insect is being studied to determine biological differences between it and a closely related species, Hylobius pinicola (Couper). This information is also essential in order to continue detailed studies on the effect of site and other factors on the abundance of H. warreni (Warren, 1956a). The first requirement for fulfilling these objectives is the development of a satisfactory rearing technique.
