Education

  1. B.S., Mount St. Mary's College, 1972
  2. Ph.D., Penn State University, 1977

Graduate Students:

Eric Bohnenblust
Neelendra Joshi

Department Focus Areas:

Ecological Applications

Research Interests :

Biology and management of arthropod pests and natural enemies on deciduous tree fruit crops; pesticide resistance management; pheromone mating disruption; evaluation of insecticides/acaricides/biologicals.

Extension:

Implementation of integrated pest management programs for deciduous tree fruit programs; control strategies and tactics for deciduous tree fruit pests.

Research Activities & Interests:

Research programs include understanding, monitoring, and managing resistance in various pests of apples; evaluating alternative non-pesticidal management tactics for fruit pests including ground cover management and pheromone mating disruption; evaluating natural enemies as biological control agents; studying the influence of insect/mite damage on fruit tree productivity; developing sampling schemes for monitoring both pest and natural enemy populations; and evaluating experimental and registered insecticides and acaricides for inclusion in fruit integrated pest management programs.

Extension Activities & Interests:

Extension programs include developing expert systems for grower use; implementing integrated pest management programs for deciduous tree fruits; and providing information and recommendations for the control of deciduous tree fruit pests.
