Effectiveness of Integrating Insecticides with Nosema pyrausta for Suppressing Populations of the European Corn Borer123

Abstract
Insecticides and Nosema pyrausta Paillot acted independently in 3 of 4 tests, and their effects were additive in terms of reducing larval populations of Ostrinia nubilalis (Hübner) and stalk cavities caused by this insect. If N. pyrausta could be established in a population as a result of its application, it is evident that this effect in combination with insecticides could provide a very effective pest-management strategy for suppressing populations of the European corn borer.
