Induction. The induction phase occurs at a genetically predetermined stage of life, and occurs well in advance of the environmental stress. This sensitive stage may occur within the lifetime of the diapausing individual, or in preceding generations, particularly in egg diapause. See more In animal dormancy, diapause is the delay in development in response to regular and recurring periods of adverse environmental conditions. It is a physiological state with very specific initiating and … See more Diapause in insects is a dynamic process consisting of several distinct phases. While diapause varies considerably from one See more Diapause in the tropics is often initiated in response to biotic rather than abiotic components. For example, food in the form of See more Diapause in insects is regulated at several levels. Environmental stimuli interact with genetic pre-programming to affect neuronal signalling, endocrine pathways, and, eventually, metabolic and enzymatic changes.

WebHere, adults congregate en masse in reproductive diapause in the fir trees. The forest conditions and large number of individuals contribute to maintaining optimal temperatures for diapause. In March, the adults emerge from this state of repose and migrate to the gulf coast, identified as the spring range (gray-filled area), where they breed ...
