Approaches in the US corn belt for the management of maize insects with resistant cultivars.

Peters D.C. | Turpin T.
Pest management is an approach to dealing with pests that emphasizes selection of control tactics that will prevent economic loss while maximizing the stability of the tactics and minimizing adverse environmental effects. Implementation of economic injury levels for maize insects in the Corn Belt is difficult to demonstrate. Avoidance of highly susceptible hybrids appears to have contributed to maize yield gains as illustrated by root lodging reduction and second-generation European corn borer tolerance. The possible impacts of high levels of simply inherited resistance on biotype formation and the allocation of plant energy to producing defense chemicals are discussed, but cannot be illustrated with examples of maize insects in the Corn Belt. The impact private seed companies and closed pedigrees have had on documenting gains in insect pest management is discussed.
