Current Research

My current research is focused on detection and control of invasive forest insect pests, particularly the emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae). EAB is a phloem-feeding beetle native to Asia that was discovered in Detroit, MI, and Windsor, Ontario in July 2002. It has caused widespread decline and mortality of ash (Fraxinus sp.).

Initially, very little was known about EAB, and the only means to detect and control infestations was to locate infested trees based on visual symptoms and then destroy the trees by cutting them down, chipping them, and burning the chips.

My research objectives are to investigate several aspects of EAB biology, including its seasonal development, semiochemical ecology, dispersal capabilities, within-tree distribution, and host finding and mating behavior. I am also investigating control methods, such as the use of systemic insecticides and biological control with natural enemies.

Research Interests

I plan to continue conducting research that addresses four strategies for managing invasive species:
  • predicting and preventing establishment of invasive pests,
  • detecting and eradicating invasive pests,
  • managing and controlling invasives, and
  • restoring landscapes affected by invasives.
  • Preventing establishment offers the most promise for protecting forested landscapes from environmental and economic losses due to invasive species. I plan to evaluate species traits that increase chances for successful invasion and to participate in research to develop risk assessments and predictive models that will allow natural resource managers to identify high-risk areas for pest surveys and detect newly invading species with a high degree of confidence. I plan to develop new methods and technologies to quickly detect and delimit the extent of new infestations and enable eradication. Eradication of newly invading species has proven most effective when new populations are at low densities and still spatially confined. I also plan to continue evaluating strategies for controlling invasive pests.

    Past Research

    I have conducted research on other invasive forest pests including the pine shoot beetle and the Asian longhorned beetle.  I investigated the chemical ecology of the pine shoot beetle including development of improved attractive lures, and inhibition of attraction using non-host volatiles.  I also studied dispersal of pine shoot beetle and its phenology across a north/south gradient.  Research on the Asian longhorned beetle included field and laboratory evaluation of the toxicity of systemic insecticides and development of an acoustic detection system  to locate infested trees.

    Why This Research is Important

    Exotic forest insects such as EAB threaten North American forests and natural resources. Native trees lack co-evolved defense mechanisms and exotic pests often invade without their associated natural enemies. Interactions of invasive pests with native ecosystems are unknown. Information on the biology, detection and management of invasive species is critical for protecting native forests and natural resources
