Effect of temperature on diapause termination and post-diapause development in Eotetranychus smithi (Acari: Tetranychidae)

Experimental and Applied Acarology, 2017
Previous studies on the spider mite Eotetranychus smithi Pritchard & Baker have shown that diapause in eggs is induced by low temperature alone and that females developed at ≤ 17.5 °C laid diapause eggs, regardless of the photoperiod. In this study, diapause eggs were kept at 5 °C and a photoperiod of 16L:8D for 0-120 days and then maintained at 25 °C ...

Diapause termination, post-diapause development and reproduction in the beet webworm, Loxostege sticticalis (Lepidoptera: Pyralidae)

Journal of Insect Physiology, 2010
Effects of photoperiod and cold exposure on diapause termination, post-diapause development and reproduction in Loxostege sticticalis were examined. Larvae were reared at diapause inducing condition (22 degrees C, L:D 12:12) consistently or transferred to long day photoperiod (L:D 16:8) and darkness (L:D 0:24) respectively, after entering into diapause.

Effects of putrescine on diapause induction and intensity, and post‐diapause development of Helicoverpa armigera

Entomologia Experimentalis et Applicata, 2010
AbstractEffects of putrescine on diapause induction and intensity, and post‐diapause development in Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) from Wuhan, Hubei, China were studied in the laboratory at different temperatures and photoperiod conditions. The results showed a generally higher incidence of diapause in putrescine‐feeding groups.

CYP314A1-dependent 20-hydroxyecdysone biosynthesis is involved in regulating the development of pupal diapause and energy metabolism in the Chinese citrus fruit fly, Bactrocera minax.

Pest Management Science, 2022
BACKGROUND Diapause is an environmentally preprogrammed period of arrested development, and characterized by metabolic depression that can occur during any development stage of insect.

Consequences of diapause on post‐diapause development, reproductive physiology and population growth of Chilo partellus (Swinhoe)

Physiological entomology (Print), 2018
We investigate the effects of diapause on post‐diapause development, reproductive physiology and population growth of Chilo partellus (Swinhoe) (Crambidae: Lepidoptera). Aestivating and hibernating larvae of C.

Debraining and diapause development in Manduca sexta pupae

Journal of Insect Physiology, 1974
Debraining experiments with wounded and normal controls were done at three different ages on diapausing Manduca sexta pupae of Kentucky and Illinois stocks. With early ages of both stocks debrained pupae escaped from diapause over an extended period of time, but wounded insects developed much earlier and at the same time as the normals. With later ages

The diapause-like colorectal cancer cells induced by SMC4 attenuation are characterized by low proliferation and chemotherapy insensitivity.

Cell Metabolism, 2023
In response to adverse environmental conditions, embryonic development may reversibly cease, a process termed diapause. Recent reports connect this phenomenon with the non-genetic responses of tumors to chemotherapy, but the mechanisms involved are ...

Seasonal diapause development and diapause termination in the European skipper, Thymelicus lineola (Ochs.)

Journal of Insect Physiology, 1985
Abstract Eggs of the European skipper, Thymelicus lineola , containing pharate first-instar larvae were brought into the laboratory at the beginning of each month from September to May and maintained at 20°C, 14L:10D. No emergence was observed within 40 days of collection before December.

Egg development patterns in diapausing and non‐diapausing species of Ruspolia

Entomologia Experimentalis et Applicata, 1988
AbstractThe egg development of the African bushcricket Ruspolia differens is shown to be direct, without any delay, and to be highly synchronised. It is also strongly temperature dependent and closely fits the thermal summation equation Days = (T°C‐14.8)/252, even if incubation temperatures (T) are changed during the course of development.

Acetylcholinesterase in Celerio euphorbiae during pupal development with diapause

Journal of Insect Physiology, 1971
Abstract Striking changes in AChE activity and Ach content occur in the tissues of the abdomen of Celerio pupae during development with diapause. These changes are sex-dependent and unrelated to the nervous system. The pattern of changes is similar in development with and without diapause, but its correlation with the morphological changes in the ...
