Cory Straub earned his Ph.D. from Washington State University and conducted his postdoctoral research at the University of Wisconsin-Madison.
The Straub lab studies the ecology of insects in agricultural systems, with the goal of identifying management strategies that reduce the need for insecticides that threaten environmental and human health. Currently, the lab is investigating how two pest management strategies – host plant resistance and intercropping - affect populations of the potato leafhopper, Empoasca fabae, the key pest of alfalfa in Northeast USA. The lab is also testing the hypothesis that host plant resistance and intercropping increase the movement of the leafhoppers within agricultural fields, and in doing so increase their vulnerability to naturally occurring insect predators. This “movement-risk” hypothesis has considerable support from natural ecosystems, but its importance for pest management in agroecosystems remains unclear.
