Related to diapause: aestivation


n. Zoology
A period during which growth or development is suspended and physiological activity is diminished, as in certain insects in response to adverse environmental conditions.

[Greek diapausis, pause, from diapauein, to pause : dia-, between; see dia- + pauein, to stop.]


(Zoology) a period of suspended development and growth accompanied by decreased metabolism in insects and some other animals. It is correlated with seasonal changes
[C19: from Greek diapausis pause, from diapauein to pause, bring to an end, from dia- + pauein to stop]


(ˈdaɪ əˌpɔz)

n., v. -paused, -paus•ing. n.
1. a period of hormonally controlled quiescence characterized by cessation of growth and reduction of metabolic activity.
2. to undergo diapause.
[1890–95; < Greek diápausis; see dia-, pause]
