Dr. Michael Toews

Research Overview

Research programs in the Toews Lab are designed to develop and test ecologically based strategies for sustainable pest management in cotton, corn and soybean.  Many of our studies are conducted with phytophagous stink bugs (Nezara viridula, Euschistus servis, and Chinavia hilaris), but we also work with thrips, whiteflies, and kudzu bugs.  Current projects integrate elements of insect behavior, sampling, monitoring, population ecology, basic biology, and movement across agricultural landscapes. 

Extension Overview

In addition to extending research findings to support Georgia cotton pest management stakeholders, we are responsible for providing statewide leadership and support in the areas of stored grain pest management and insect management in processing facilities.

Teaching Overview

Dr. Toews is responsible for teaching Insect Ecology (ENTO 8500, co-taught with Dr. Kerry Oliver), and Concepts in IPM (ENTO 8820, co-taught with Drs. David Buntin, and Will Hudson).
