Abstract
Maintaining an appropriate seasonality is perhaps the most basic ecological requisite for insects living in temperate environments. The basic ecological importance of seasonality is enough to justify expending considerable effort to accurately model the processes involved. For insects of significant economic consequence, seasonality assumes additional importance because management decisions are often based on seasonal timing. In gypsy moth management, timing of BT applications and determining an efficient sampling interval for placement of pheromone traps are two such applications. We are, therefore, in the process of developing models required for representation of gypsy moth seasonality. Model representations currently under consideration are those for egg diapause and embryogenesis, and larval phenology.
