(dī'ă-pawz),
A period of biologic quiescence or dormancy with decreased metabolism; an interval in which development is arrested or greatly slowed.
[dia- + G. pausis, pause]

diapause

/di·a·pause/ (-pawz) a state of inactivity and arrested development accompanied by greatly decreased metabolism, as in many eggs, insect pupae, and plant seeds; it is a mechanism for surviving adverse winter conditions.

diapause

(dī′ə-pôz′)
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.

diapause

a period of arrested growth and development in insects which is under the control of the endocrine system. Diapause is an adaptation to avoid adverse conditions, but does not automatically end with the termination of the adverse conditions as it is genetically determined. However, diapause can be ‘broken’ by an appropriate environmental change, or artificially by temperature shocks or chemical stimulation.
