A genome-wide association study implicates the olfactory system in Drosophila melanogaster diapause-associated lifespan extension and fecundity [PDF]
eLifeThe effects of environmental stress on animal life are gaining importance with climate change. Diapause is a dormancy program that occurs in response to an adverse environment, followed by resumption of development and reproduction upon the return of ...

Journal of Insect Physiology, 2009 Metabolic depression is a highly conserved feature of insect diapause, and an increase in metabolism is a reliable indicator of diapause termination and the initiation of post-diapause development. The trajectory of metabolic rate following diapause termination can guide the identification of important physiological and developmental landmarks during ...

Using diapause as a platform to understand the biology of dormancy [PDF]
Open BiologyDiapause is a fascinating form of biological dormancy that is employed by a broad array of animals as a survival strategy to endure adverse environmental conditions.

Role of water and moisture in diapause development (A review)
European Journal of Entomology, 2003 While observational studies led to the assumption that water or moisture (W/M) is a prerequisite for diapause development, the experimental research indicates rather the opposite: usually W/M is needed as late as for the post-diapause resumption of ...

Molecular signatures of diapause in the Asian longhorned beetle: Gene expression
Current Research in Insect Science, 2023 Most previous studies on gene expression during insect diapause do not address among-tissue variation in physiological processes. We measured transcriptomic changes during larval diapause in the Asian longhorned beetle, Anoplophora glabripennis ...

Circadian clock genes, ovarian development and diapause [PDF]
BMC Biology, 2010 Insects, like most organisms, have an internal circadian clock that oscillates with a daily rhythmicity, and a timing mechanism that mediates seasonal events, including diapause. In research published in BMC Biology, Ikeno et al. show that downregulation of the circadian clock genes period and cycle affects expression of ovarian diapause in the insect ...

Proceedings of the National Academy of Sciences of the United States of America, 2022 Significance Many insects have evolved a developmental arrest called diapause to overcome unfavorable seasonal changes. In pupal diapause species, the fat body is structurally intact in diapause pupae for months, whereas it undergoes cell dissociation ...

Endocrine Regulation of Lifespan in Insect Diapause
Frontiers in Physiology, 2022 Diapause is a physiological adaptation to conditions that are unfavorable for growth or reproduction. During diapause, animals become long-lived, stress-resistant, developmentally static, and non-reproductive, in the case of diapausing adults.

Two distinct aphid diapause strategies: slow development or development arrest
Journal of Insect Physiology, 2023 Aphids adapt to unfavourable environmental conditions, such as low temperatures in winter, by laying diapausing eggs that overwinter. Diapause is a stress-resistant and developmentally arrested stage that can be adopted in order to increase the chance of survival in adverse environmental conditions.

Drosophila americana Diapausing Females Show Features Typical of Young Flies. [PDF]
PLoS ONE, 2015 Diapause is a period of arrested development which is controlled physiologically, preprogrammed environmentally and characterized by metabolic depression that can occur during any stage of insect development.
