Abstract

The beech leaf-mining weevil, Orchestes fagiL. (Coleoptera: Curculionidae) is a common pest of European beech, Fagus sylvatica L. (Fagales: Fagaceae), in its native European range which has recently (2012) become established in Nova Scotia, Canada where it similarly damages American beech, F. grandifolia Ehrh. The objective these studies are to develop effective strategies to monitor and control of this new invasive species. Chapters focus on the life history and phenology of both O. fagi and its novel host, F. grandifolia. Evidence is presented to support the existence of a male-produced repellent pheromone and for males to have trichromatic vision. Female O. fagi had larger electroantennal responses to host volatile organic compounds. GC-FID analyses of F. grandifolialeaf development indicated fluctuating volatile profiles throughout the growing season. The studies in this thesis provide phenological and biochemical context for future studies on O. fagi host location tactics and the development of integrated pest management strategies.
