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.

An obligatory characteristic of univoltine species is a long diapause period during certain development phases.
Storage of insects can be achieved by holding them either in diapause or non diapause conditions under low temperatures (Nordlund and Morrison,
Oriental fruit moth, Grapholita molesta (Lepidoptera: Tortricidae), is a major pest of tree fruits worldwide, overwinters in mature larva diapause. However, little is known about the physiological explanation for diapause development in this pest.
This arrested development is followed by diapause, in which development is arrested, metabolic activity is greatly reduced, and the resistance to severe physiological stress is high (Drinkwater and Crowe, 1987; Liang and Macrae, 1999).
We did this to ensure that flies in deep diapauses or with two-year life cycles had adequate time to eclose.
In the cold months, the pupal stage may last several months, causing the pupa to go into diapauses. The adults appear from the pupae close to the surface of the tree whilst the exterior weather causes them to break diapauses.
Annual fish are unique in the fact that they develop their eggs very slowly and can go up through to three diapauses, depending on genetic and environmental factors (Myers 1952; Wourms 1972).
filipjevi did not show any diapauses as the juveniles hatched immediately at the beginning of the winter wheat growing period.
