Research Interests

I specialize in applied entomology and have extension, research, and teaching responsibilities in field crop entomology and arthropod pest management.  My research currently is focused on integrated pest management of wheat stem sawfly, Cephus cinctus, and other key pests of winter wheat with emphasis on the development of resistant cultivars and other sustainable management practices.  I am initiating a new project on alfalfa weevil management.  Much of my extension information is summarized in the High Plains Integrated Pest Management Guide as well as in fact sheets found on the Colorado State University Extension website.

Courses I Teach

Livestock Entomology (Spring)

Identification, biology, and management of insect, tick, and mite pests.


Understanding Pesticides (Spring Even Years)

Identification, properties, use, labeling, environmental interactions, and application of major classes of pesticides.


Integrated Pest Management (Spring Odd Years)

Concepts of integrated pest management and the strategies and tactics employed in the application of these concepts.


Advanced Integrated Pest Management (Spring Odd Years)

Concepts of integrated pest management and the strategies and tactics employed in the practical application of these concepts.
