Available in PDF, EPUB and Kindle. Book excerpt: An integrated pest management model is developed for the northern corn rootworm, Diabrotica longicornis, and the western corn rootworm, Diabrotica virgifera, insect pest of corn. Uncertainty and risk aversion are incorporated into an economic threshold model. Two control actions, soil insecticide and crop rotation, are included. The effect of crop insurance and improved scouting accuracy on insecticide use is evaluated. The rootworms population is considered to be a common property resource with an exhaustible stoock of susceptibility to insecticide. A second objective of the study is to evaluation the potential benefits of a regional approach to corn rootworms control, internalizing the externalities of insecticide resistance and pest movement among farms. A genetic model is used as the basis for predicting the influence of insecticides use rate on resistance buildup. The regional approach is compared with an individual farm approach in an intertemporal aoptimization model solved by nonlinear programming. The empirial results indicate that increased risk aversion reduces the economic threshold for insecticide application, Increased risk aversion also reduces the economic threshold for crop rotation when corn has a large comparative advantage over soybeans. The effects of risk aversion on insecticide use is uncertain. Increased risk aversion may increase "insurance" insecticide application on lightly infested fields, but my also lead to diversification to another crop on heavily (...).
