Pests such as Hessian fly occasionally infest wheat in experiments designed to examine disease management practices; in such cases our team also quantifies damage by the insect pests. Collaborators include multi-disciplinary teams of scientists in Washington, Idaho and Oregon. Representative papers include the following.

  • Smiley, R.W., J.A. Gourlie, R.G. Whittaker, S.A. Easley, and K.K. Kidwell. 2004. Economic impact of Hessian fly (Diptera: Cecidomyiidae) on spring wheat in Oregon and additive yield losses with Fusarium crown rot and lesion nematode. Journal of Economic Entomology 97:397-408.
