Department Focus Area

Ecological Applications

Research Interests

Insect ecology and management in agroecosystems

Extension

Integrated pest management in vegetables.

Research Activities & Interests

I am interested in the structure, dynamics, and management of insect populations. Resulting sampling plans have been adopted in alfalfa, hardwood forests, and leafy greens in the Caribbean; regional monitoring programs have been developed for diversified vegetable farms. Students have mapped insect density in alfalfa, potatoes, tomatoes, vineyards, and within protected structures. Research also develops management options based on an understanding of biological and ecological processes. Priority is placed on economically feasible technologies that improve farm-worker and environmental safety. Current work is looking at biological controls, transgenic crops, and regional monitoring networks.

Extension Activities & Interests

My Extension assignment is in vegetable pest management. The Extension education program works with county-based staff at sites accessible to clientele. Yearly, I contribute to the Commercial Vegetable Production Recommendations guide for Pennsylvania, and to a regional multi-state web-GIS presentation of pests of sweet corn.
