Abstract

The in vivo incubation period of Beauveria bassiana mycosis of the European corn borer, Ostrinia nubilalis, was found to vary in response to temperature of incubation, level of initial exposure (dose), and the age of the host larvae. Incubation temperature was found to be the dominant factor affecting disease development within each of the host instars examined, while dose produced significant effects only in the early instars. A nonlinear regression model was used to construct three-dimensional stimulus-response surfaces for each host instar. This model has provided reasonable predictions of the disease incubation period when used within the temperature regimes found throughout New York State.
