EDUCATION

PROFESSIONAL AREAS OF EMPHASIS

EXTENSION ACTIVITY
I serve as the entomology resource person for 47 counties in the Rolling Plains and Blacklands regions of Texas. My program focuses on transferring technology to producers in the Southern Rolling Plains.  More specifically the program focuses on Integrated Pest Management-tactics in different cropping systems.  Translational research has emphasized the use of Bacillus thuringiensis (Bt) cotton in the low input cropping systems of the Southern Rolling Plains.  The work has shown that although the insecticide technology is of low value to producers, the varieties now being used are better agronomically and producers should take advantage of the technology.  The other aspect of the translational research has been the incorporation of new seed treatments into cropping systems.  The early work showed that the seed treatments can benefit producers by protecting their crops and yet not have an impact on natural enemies in grain sorghum systems.  More recent work has concentrated on the use of seed treatments in wheat to manage greenbugs and Hessian fly.

Collaborative research with the Entomology Department has been measuring predator movement and developing strategies of using the movement to manage insect pests.  The next step will be to study the movement of a key pest, cotton fleahoppers, in different regions in Texas and develop management strategies for this cotton pest.

I also have direct administrative duties for 14 Extension Entomologists and 5 Extension Program Specialists.
