Research Activities & Interests:
My laboratory has 4 major thrust areas:
1) Impacts of induced plant defenses on the efficacy of baculovirus in lepidopoteran hosts.
2) The Asian longhorned beetle (Anoplophora glabripennis), an introduced insect from China, harbors a rich diversity of gut microbes, which include both bacteria and fungi. We are broadly interested in the hypothesis that microbial symbionts in cerambycids drive host range. Currently we are investigating mechanisms of resistance against this beetle to determine if plant secondary metabolites act directly against the gut symbionts or indirectly through negative impacts on the beetle itself.
3) Semiochemical communication in the Asian longhorned beetle, including a long-range male-produced pheromone and a sex specific, female produced trail pheromone.
4) To prevent invasive, exotic species (insects, nematodes, and fungi) from moving around the world in wood packing materials and wood products, international regulations require these materials to be properly treated before they can be shipped out of the country of origin. As a member of the International Forestry Quarantine Research Group, an advisory body to the technical panels of the International Plant Protection Convention (IPPC) of the United Nations, I collaborate on research with industrial engineers and wood products scientists to drive adoption of dielectric heating technology as an alternative phytosanitary treatment to methyl bromide fumigation. This method was recently approved as a new treatment under ISPM-15. We are also involved in providing input to the technical panels on development of appropriate treatment schedules and guidance manuals.
