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.
