Description
Summary:A simulation model was used to examine the idea thea diapause development in the egg of the gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae), is a dynamic process in which the response to temperature gradually changes over the course of development. No clear demarcation of diapause and post-diapause development was presumed. Rather, an initial developmental response having low thresholds and optimal temperatures was assumed to give way gradually to a response having higher thresholds and optima. With one set of parameter values, the model produced results comparable to those from experiments conducted with Russian and Japanese Populations of the gypsy moth, and consistent with one set of data from North America. However, these results were inconsistent with data from other, more detailed experiments conducted with North American eggs. Changes to the model that improved the fit to the North American data were then determined. The model served to identify areas of disagreement among the published data, and to suggest experiments that will help resolve unanswered questions about diapause development in the gypsy moth.
