Biography

Research Specialization - The long-term mission oriented objective of research conducted in my laboratory is to improve integrated pest management of insects affecting woody ornamental plants. The primary research focus is to develop a better understanding of the biology and ecology of the herbivorous insects through studies of their interactions with host plants, competitors, and natural enemies, and determine the influence of environmental stress on those interactions. Recommendations to modify management practices emerge from this research, resulting in more judicious insecticide use and increased reliance on biological and cultural control, while maintaining the aesthetic value of the plants.

Research Area

Fundamental research projects in the laboratory have included studies of the biology and ecology of introduced insects in urban environments. Plant communities in urban environments are often diverse combinations that are native or introduced in origin, rich in the number of species, and complex in structure and distribution. Insect communities change as new species are introduced. Interactions among the phytophagous insects are effected by the different growing conditions in these environments. At the boundaries of urban areas are native communities of plants and arthropods that suffer pressures from urbanization and anthropogenic pollution. We have examined the interactions of host suitability, host species susceptibility, and natural enemies on insect population biology. A recent focus of the biological control research has been to determine how natural enemies contribute to replacement of herbivore species in communities of introduced species. We have also conducted research on the pheromone communication systems of bark beetles and have examined the interactions among bark beetles, their associated fungi, and host conifers. As part of a interdisciplinary research focus on the impact of environmental stresses on interactions between plants and their herbivores, recent studies have been conducted on the effect of temperature, humidity and insolation on settling behavior and survival of a leaf-galling psyllid, the interactions between mycorrhizal fungus colonization of plants and the herbivore populations, and the influence of ozone and nitrogen deposition on arthropod communities associated with black oak, ponderosa pine, and bracken fern.
