Differences in the Development of Internal Reproductive Organs, Feeding Amount and Nutrient Storage between Pre-Diapause and Pre-Reproductive Harmonia axyridis Adults

open access: yesInsects, 2019
Diapause control is one of the successful methods for long-term cold storage of biological control organisms without decreasing their fitness. Sufficient preparation before diapause is essential for successful diapause initiation and maintenance ...

Temperature-induced embryonic diapause in chickens is mediated by PKC-NF-κB-IRF1 signaling

open access: yesBMC 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.

Seasonal and geographical adaptations in the parthenogenetic stick insect, Ramulus mikado (Phasmatodea: Phasmatidae)

open access: yesEuropean Journal of Entomology, 2022
Seasonal and geographical adaptations in terms of obligatory embryonic diapause in the parthenogenetic stick insect, Ramulus mikado, were studied. First and second instar nymphs were collected at locations at three latitudes in Japan and reared in the ...

Phenological shifts and increases in voltinism within a moth community over a century of anthropogenic change. [PDF]

open access: yesEcology
Abstract In temperate ecosystems, warming temperatures can advance spring phenology, extend autumn phenology, disrupt dormancy regulation, result in phenological mismatch across taxa, and even lead to increases in the number of generations per year (i.e., increases in voltinism).

Molecular Regulators of Embryonic Diapause and Cancer Diapause-like State

open access: yesCells, 2022
Embryonic diapause is an enigmatic state of dormancy that interrupts the normally tight connection between developmental stages and time. This reproductive strategy and state of suspended development occurs in mice, bears, roe deer, and over 130 other ...

Life History of \u3ci\u3eMesovelia Mulsanti\u3c/i\u3e (Hemiptera: Mesoveliidae) in Southern Illinois [PDF]

open access: yes, 2017
The life history of Mesovelia mulsanti was studied during 1983-1986. This species was apparently trivoltine with a partial 4th generation at the end of the year. It overwintered as eggs. First ins tars appeared in mid-April followed by marked overlapping

Steroid hormone ecdysone deficiency stimulates preparation for photoperiodic reproductive diapause.

open access: yesPLoS Genetics, 2021
Diapause, a programmed developmental arrest primarily induced by seasonal environmental changes, is very common in the animal kingdom, and found in vertebrates and invertebrates alike.

Predicting the potential geographical distribution of the harlequin ladybird, Harmonia axyridis, using the CLIMEX model - BioControl [PDF]

open access: yes, 2008
Harmonia axyridis (Pallas, 1773) (Coleoptera: Coccinellidae) is a ladybird beetle native to temperate and subtropical parts of Asia. Since 1916 populations of this species have been introduced throughout the world, either deliberately, or by accident ...

Cell cycle dynamics during diapause entry and exit in an annual killifish revealed by FUCCI technology

open access: yesEvoDevo, 2019
Background Annual killifishes are adapted to surviving and reproducing over alternating dry and wet seasons. During the dry season, all adults die and desiccation-resistant embryos remain encased in dry mud for months or years in a state of diapause ...

Life Cycles of \u3ci\u3eLeuctra Duplicata\u3c/i\u3e and \u3ci\u3eOstrocerca Prolongata\u3c/i\u3e in an Intermittent Streamlet in Quebec (Plecoptera: Leuctridae and Nemouridae) [PDF]

open access: yes, 2017
Large populations of Ostrocerca prolongata and Leuctra duplicata developed in a small intermittent stream in the foothills of the Laurentian Highlands of Quebec. Both species were univoltine in 1974-1975.
