The physiology of insect diapause

WebbFunctional binding sites for miR‐2765‐3p in the 3′ untranslated region of FoxO in Galeruca daurica are discovered and indicate that the JH/miR‐ 2765‐ 3p/FoxO axis plays a vital role in the regulation of reproductive diapause in G. daurICA. The forkhead box O (FoxO), as a conserved transcription factor, plays an indispensable role in regulating insect diapause. Webb22 maj 2013 · Physiological and gene expression studies of insect diapause have uncovered processes commonly involved in the maintenance (reviewed in ) or termination [43,50] of diapause. These hallmarks include shifts in metabolic pathways [ 4 , 51 – 53 ], upregulation of stress response genes [ 45 , 54 ], changes in cell-cycle arrest [ 40 , 41 , 55 …

Webb10 dec. 2024 · Diapause is a period of suspended or arrested development during an insect's life cycle. Insect diapause is usually triggered by environmental cues, like changes in daylight, temperature, or food availability. Diapause may occur in any life cycle stage—embryonic, larval, pupal, or adult—depending on the insect species.
