Description of Research
Biosystematics of Therevidae and Phylogeny of the Asiloidea
I am elucidating the phylogenetic relationships of the Therevidae (stiletto flies) and other families of the Asiloidea (Diptera: Brachycera). Through the use of morphological, geographical, genetic, behavioral, and ecological characteristics, a large team of researchers and graduate students is describing and modeling the historical relationships among these taxa. We are employing web interfaces and powerful databases in our study. Our team has an NSF PEET (Partnerships for Enhancing Expertise in Taxonomy) and Schlinger Foundation grants for this project, which run through the fall, 2005.
Biodiversity, Bioindicators, and the Interchange of Biota between Agricultural and Wild Systems
The importance of understanding global aspects of biodiversity cannot be overstated. Our effots are now focused on Madagascar and New Caledonia, and we are attempting to become involved with biodiversity questions in the more xeric zones of Spain, Bolivia, and Cuba. Bioindicators are an important means of ascertaining environmental quality; we are pursuing hypotheses that could lead to breakthroughs in this area for xeric climates and agroecosystems. Biotic movement between natural and agricultural ecosystems is an important factor in maintaining the viability and sustainability of those systems. My interests lie in understanding how species and their genes flow between systems, and how an understanding of this can contribute to the knowledge base underpinning the issues of sustainability.
Plant Virus Epidemiology
Plant virus epidemiology is a complex study involving interactions of plants and viruses, viruses and vectors, and vectors and their environment. Work to date has stressed the behavioral ecology of vectors, primarily of soybean mosaic virus, bean common mosaic virus, and barley yellow dwarf virus. My goal has been to explore alternate control tactics, such as modifying vector flight or probing behavior, using live barriers as dampers to field spread, breeding for host plant resistance, and employing chemicals to disrupt the transmission process. These tactics have been incorporated into models of plant virus epidemics that can be used to develop appropriate control strategies.
Aphid Migration and Movement
Understanding the complex aspects of pest migration: source area, distribution in the atmosphere, distribution on an area-wide basis, and local movement and settling requires an intensive team approach. Results of this study are already beginning to provide a predictive capability to determine timing and abundance of aphid invasion into, and possible colonization of, crops.
International Crop Protection and Soybean Pest Management
Because my position was earlier supported by the International Soybean Program (INTSOY), I developed expertise and guidelines for managing insect pests of soybeans and insect vectors of soybean diseases, especially for developing countries. I sought generalized technologies for establishing pest management programs, including sampling plans, monitoring strategies, and establishing ecologically sound and environmentally compatible methods for controlling complexes of soybean pests. I also endeavored to developing countries desiring to undertake, or currently undertaking, soybean cultivation. This developed into a broad-based effort to assist developing countries in the development and execution of crop protection, across crops and across disciplines.
