Areas of Interest
My research interests are varied but center around insect systematics and entomological diversity as broad fields of exploration – I often refer to this as “ecosystematics.” I am interested in the interactions of insects with their environments, especially as those environments are harsh, unusual, or vanishing. This often includes areas that are managed such as parks, reserves and reservations and even agricultural lands. For many years, some of my students and I conducted intensive survey work and concurrent ecological studies of the Hanford Nuclear Site located in south central Washington State. We currently have biodiversity survey studies of several native Palouse Prairie sites that are located in eastern Washington.
My systematic interests also are varied with primary groups of interest including the dipterous family Ephydridae (shore flies), moths, and aquatic Coleoptera and Hemiptera in general. Current investigations include general studies of the insect fauna of Guam (and Micronesia), especially shore flies, and the moths of the Washington. We also have cooperative studies in Guatemala.
I am also involved in applied studies, especially as they exam or build-upon general principles of entomology. Recent projects are in corn (especially corn earworm) management and field crops. I am looking at the distributions and management of noctuid moths. I am also pursuing studies that examine at the chemical ecology of non-pheromone insect attractants for moths and pestiferous wasps. Much of this research is conducted in collaboration with Dr. Peter Landolt at the USDA ARS lab in Wapato, WA.
I am interested in how insects and people interact at all levels including those often termed cultural entomology. Most of my activities are at the undergraduate level where I teach a courses titled “Insects and People” and “Entomology and Human Health” to non-science majors. I enjoy teaching and the opportunity to interact with students at all educational levels. My graduate students are often involved in my teaching, as are gifted undergraduates.
