Diapause is a seasonal adaptation strategy of insects and animals in which biological functions are put on hold, such as insect eggs that remain dormant until conditions are more favorable to hatch. This is not a passive response of dormancy to adverse situations but an actively induced state that takes place well in advance in anticipation of natural conditions. Although it has been hypothesized that the neuroendocrine systems are associated with seasonal reproductive plasticity, the morphological, physiological, behavioral, reproductive responses of diapause remain unclear.
