Physiological Entomology, EarlyView.Larval diapause intensity of Monochamus alternatus follows a declining curve, beginning with an initial refractory phase and reaching termination after approximately 110 days of chilling at 9°C. Residual inhibitory state strongly influenced post‐chilling development; additional chilling shortened the diapause period more at 18°C than at warmer ...

Physiological Entomology, EarlyView.Experimental rearing of Orthosia gothica and Orthosia cerasi larvae under four controlled climate‐chamber treatments (15°C vs. 20°C; 24h darkness vs.12h light/12h dark) to isolate temperature and light effects on development. Repeated measurements of larval body size, biomass and pupation timing to quantify how growth rates and developmental duration ...

Embryonic diapause: a unique stage of development
Clinical TheriogenologyEmbryonic diapause is a unique stage of development that occurs in some mammalian species. Diapause serves as an evolutionary reproductive strategy to maximize the survivability of dam and offspring. Although individual mechanisms of control vary among species, the overarching physiology of diapause extends the length of pregnancy to delay parturition ...

The Biological Bulletin, 1953 The endocrine control of the pupal diapause of the Cecropia silkworm has been the principal theme of the preceding papers of this series. A considerable body of evidence is now at hand pointing to the prothoracic glands as the source of a hormone which reacts with the tissues to terminate the pupal diapause.

Physiological Entomology, EarlyView.We investigated maternal effects in Schizotetranychus brevisetosus (Tetranychidae), where females oviposit summer and winter eggs in response to photoperiod on evergreen hosts. Developmental rates of immature individuals increased linearly from 15°C to 35°C, but winter and summer eggs developed faster at low and high temperatures, respectively ...

Austral Entomology, Volume 65, Issue 2, May 2026.Abstract Croitana Waterhouse, 1932 (Trapezitinae) is a small genus of skippers endemic to Australia, with most species restricted to semi‐arid and arid biomes where the larvae specialise on grasses (Poaceae) in the genera Neurachne R.Br., Enteropogon Nees and Austrostipa S.W.L. Jacobs & J.Everett.

Biological Reviews, Volume 101, Issue 2, Page 911-925, April 2026.ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...
