Prepupal diapause reduces adult lifespan in the solitary alfalfa leafcutter bee [PDF]
Scientific ReportsDiapause is an adaptation that allows many insects to survive adverse environmental conditions. While diapause-associated trade-offs with reproduction are well-documented, its potential impact on lifespan and long-term adult physiology remains poorly ...

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 ...

Dosage-dependent regulation of embryonic diapause by sorbitol dehydrogenase in the silkworm, Bombyx mori. [PDF]
PLoS GeneticsInsects have evolved diapause to cope with harsh environmental conditions, during which their metabolism undergoes significant remodeling. The silkworm, Bombyx mori, enters diapause in the early embryonic stage, a process critically regulated by the ...

Hormonal Regulation of Diapause and Development in Nematodes, Insects, and Fishes
Frontiers in Ecology and Evolution, 2021 Diapause is a state of developmental arrest adopted in response to or in anticipation of environmental conditions that are unfavorable for growth. In many cases, diapause is facultative, such that animals may undergo either a diapause or a non-diapause ...

European Journal of Entomology, 2022 Maternal silkworms (Bombyx mori) of bivoltine strains are destined to produce either diapause or non-diapause eggs depending on environmental factors, such as, temperature and photoperiod experienced during the egg and larval stages.

Temperature-induced embryonic diapause in chickens is mediated by PKC-NF-κB-IRF1 signaling
BMC Biology, 2023 Background Embryonic diapause (dormancy) is a state of temporary arrest of embryonic development that is triggered by unfavorable conditions and serves as an evolutionary strategy to ensure reproductive survival.

Environmental impacts on diapause and survival of the alfalfa leafcutting bee, Megachile rotundata.
PLoS ONE, 2021 Megachile rotundata exhibits a facultative prepupal diapause but the cues regulating diapause initiation are not well understood. Possible cues include daylength and temperature. Megachile rotundata females experience changing daylengths over the nesting

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.
