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]


a period of rest or quiescence between phases of growth or reproduction.

During the autumn and winter, they migrate to enormous depths where they enter a state of hibernation called diapause.
from sticks pleading that pink bollworm Larvae undergo 'Diapause' in these bolls as Pupae and come out of bolls in summer season to hit crops for survival.
apply Chisel plough so that pink bollworms undergoing diapause and their Pupae get killed.
Their survival technique usually involves "diapause," a period of dormancy where the metabolic activity of the insect slows down significantly, which decreases the amount of energy required.
The overwintering stage of cecidomyiids is usually the full-grown larva that uses a spatula structure on the prothorax to dig into soil before entering diapause (Gagne 1989).
If you decide to remove this old growth in middle or late spring, remember that many insects are in hibernation or "diapause" so the stems should be carefully bundled, tied and tossed loosely on the compost pile or placed upright against a tree or fence.
They are found in different parts of the world and are known to survive tough conditions by adapting or going into a state of dormancy called diapause.
Including over 3,500 references, this authoritative work serves as an access point to the primary literature on their life histories, higher systematics, diapause and seasonal cycles, pathogens, symbionts, semiochemistry, and pest management control strategies for pentatomoid bugs.
While monarchs are known to enter a period of reproductive diapause on their return to Mexico (Goehring & Oberhauser 2002), there are several documented cases of fall reproduction in Texas that complement these observations.
Additionally, photoperiod may be involved in the initiation and termination of diapause in copepods such as Calanus finmarchicus (Miller et al., 1991); however, many questions regarding the control of diapause remain, and alternative hypotheses have been proposed recently (e.g., the lipid accumulation window; Johnson et al., 2008).
Many insects enter diapause at a species-specific embryonic stage (Tauber et al.
