- Ph.D., Entomology, Texas A & M University, College Station, TX, 1984
Courses Taught
- ENTO 5123/5120L : Biological Control / Biological Control Laboratory
Graduate Student
- Carey Minteer - Graduate Student (Ph.D.)
Program Area
- Biological Control : Parasites and Predators
- Wheat Insects
Research Area
- Deployment of a unique treatment threshold in cotton which incorporates the action of beneficial insects (PDF)
- Evaluation of the impact of generalist predators in selected row-crop systems, particularly cotton and wheat.
- Evaluate the impact of newer cotton insecticides on beneficial insects and to develop strategies for their effective use while minimizing their disruption of natural enemy populations.
- Modification of treatment thresholds in wheat to minimize unnecessary inputs while maintaining yield potential. Thresholds have been modified for control the aphid vectors of barley yellow dwarf virus and armyworm.
- Implementation of a biological control program for spotted knapweed in Arkansas. Current project is an evaluation of Urophora quadrifasciata, an exotic natural enemy already present in Arkansas.
