Insect Pests of Ornamentals and Turfgrass (BSci 497) - Course covers the recognition, biology, and management of insects and mites injurious to ornamental trees, shrubs, greenhouse crops, and turf. Emphasis is on Integrated Pest Management (IPM) and ecologically based management strategies. An insect and plant damage collection is required. (Lecture and lab, 4 credits)

Biology of Insects (BSci 337) - Course provides an overview of the biology, and evolution and diversity of insects and their relatives. Insect morphology, physiology, behavior and ecology, and the impacts of insects on humanity and the management of pest populations are discussed. An insect collection is required. (Lecture and lab, 4 credits)

My program develops and implements research-based integrated pest management (IPM) programs for a variety of clientele involved with the production and maintenance of ornamental plants and turf, i.e., nursery, greenhouse, turfgrass, and school grounds professionals, IPM practitioners, extension personnel and master gardeners, and government agencies. My program encompasses and integrates research and outreach activities.  These activities include: basic and applied ecological studies of plant - herbivore - natural enemy interactions to elucidate innovative pest management options; development of management practices that reduce reliance on chemical pesticides and integrate biological control and other non-chemical options; implementation of demonstration programs to further the adoption of IPM; training personnel in ornamental and turfgrass industries; development of educational materials to facilitate training; and providing service to the green industries. The overall goals of my program are to develop sustainable ornamental and turfgrass systems that prevent pest outbreaks; to provide unique opportunities for undergraduate and graduate education in the discipline of IPM, and landscape and community ecology; and to increase the adoption of IPM practices by providing exceptional educational outreach programs.
