Biofuels and ecosystem services

Sustainability of the nation’s bioenergy feedstock production relies on selection and placement of energy crops that efficiently generate biomass without compromising existing agricultural systems. Pest and beneficial arthropods (e.g., pollinators, predators) will occur in these feedstock crops, but the effect of habitat utilization is unknown, as there is little experience with expansive monocultures of biofuel crops. This research will advance knowledge of risks or benefits from placing large biofuel crop monocultures into established agricultural landscapes.

Mobile technologies and natural enemies

This project, "Using Mobile Technologies to Forecast and Track Natural Enemy Effectiveness on Cereal Aphids in Changing Landscapes" was funded by the Environmental Protection Agency (EPA). The overarching goal of this project was to expand the accessibility of existing pest management tools by using smartphone technologies and other sophisticated yet accessible devices to develop a wide-area monitoring and management system to account for changes in land use and bioenergy demands.

Managing H. zea in late-season sorghum

Several lepidopteran species infest developing panicles. Larval identification is challenging and time intensive, so current recommendations are often simplified by treating all larvae equally across species. Consequently, the yield-loss model developed for corn earworm (Helicoverpa zea) by Buckley and Burkhardt (1962) has been the foundation for management recommendations in modern sorghum Integrated Pest Management (IPM) programs for the last 49 years.
