ABSTRACT

This chapter analyzes the most studied seasonal development patterns of the Pentatomoidea living in the temperate climate, attempts to reveal the eco-physiological mechanisms participating in the formation of a certain type of seasonal cycle, and estimate the similarities and differences in the seasonal development patterns of species of different taxa within this superfamily of true bugs. Insects provide extensive material for studying the evolution and diversity of seasonal adaptations and annual cycles based on these adaptations. Every insect species, and in many cases every population, possesses its own specific annual cycle that differs from those of other populations or species, including those that are taxonomically close or sympatric. The chapter proposes a system of seasonal adaptations involved in the formation of various annual cycles of insects. In the univoltine seasonal cycle, only one generation develops during a vegetative season or year. Univoltinism is subdivided into endogenous univoltinism and exogenous univoltinism.
