Nyrop, Jan Peter

Professor

I joined the Geneva Entomology department at Cornell in 1985 as an assistant professor, was promoted to associate professor in 1992, and full professor in 1999. I served as chair of the Ithaca entomology department for two and half years and am now a Senior Associate Dean in CALS. My research has three programmatic themes; biological control, pest control decision making, and quantitative population ecology. I have a strong commitment to teaching, extension and outreach. Currently I help lead lectures in a course entitled “Natural Enemies and Invasive Species,” in collaboration with Dr. Ann Hajek on the Ithaca campus. My extension efforts focus on biological control and developing pest management guidelines that promote sustainability.

research

research and scholarship focus

The goal of my research is to develop the tools required for biologically-based management of arthropods in horticultural crops. I work towards this goal along three programmatic thrusts; biological control, pest control decision making, and quantitative population ecology. My biological control research focuses on improving the effectiveness of natural enemies in selected cropping systems. Pest control decision making is one of the foundations of pest management and this research addresses tools for measuring pest abundance, understanding pest impact on crops, and risk assessment for non-indigenous species.

teaching

teaching focus

I jointly teach a three credit course on invasive species and biological control. The purpose of the course is for students to learn the conceptual aspects of biological control and invasion ecology and to appreciate the practical application of these concepts. These subjects fit well together because one of the first lines of defense against invasive species is use of biological control agents and biological control agents can become invasive. I enjoy teaching the course because it integrates fundamental biology, applications of biological understanding, and social and economic issues. This breadth lends itself to a variety of teaching styles and active, participatory learning.

service

outreach focus

I assist the producers and users of mass-produced biological control agents in understanding the issues surrounding quality control and in developing methods for assessing the quality of products. This is a world-wide group of constituents.|I make presentations on and help to develop recommendations based on my research in various horticultural cropping systems. Constituents are primarily in New York and the northeast.|I help to coordinate and staff entomological displays that strive to convey the importance and excitement of entomology to a wide constituency. Examples include Empire Farm Days, Fun on the Farm, and Insectapalooza, the annual entomology open house.
