Because the development of any successful pest management program begins with a foundation of basic biological information, the major thrusts of Dr. Barrett’s research program have been to examine the biology and ecology of key tortricid moth pests in commercial apple orchards and of the chestnut weevil in agroforestry systems found in the Midwest. Specifically, he is investigating the sublethal effects of ecdysone-agonist insect growth regulators on codling moth and leafroller reproduction and orientation. In addition, Dr. Barrett is working with Dr. Terrell Stamps in determining the major volatile components of chestnut, and to evaluate the individual volatile components as preferred attractants by adult chestnut weevils.

His teaching duties include two undergraduate courses and one graduate-level course. The main objective for Barrett’s undergraduate courses, PS 3710 (Introductory Entomology) and 3715 (Insect Diversity) is to introduce students to the world of insects through their vast ecological and morphological diversity and to help them gain a better appreciation for the role insects play in the scheme of life. Barrett’s graduate course, PS 8720 (Insect Behavior), introduces students to the breadth of behaviors found in insects. Contemporary insect behavior is a multidisciplinary approach about how and why insects do the things they do, and the biological significance of their behavior in the context of nature.

Barrett’s extension responsibilities include the development and delivery of management tactics for arthropods affecting fruits, vegetables, turf and woody ornamentals.
