Diapause induction and termination in the small brown planthopper, Laodelphax striatellus (Hemiptera: Delphacidae). [PDF]

open access: yesPLoS ONE, 2014
The small brown planthopper, Laodelphax striatellus (Fallén) enters the photoperiodic induction of diapause as 3rd or 4th instar nymphs. The photoperiodic response curves in this planthopper showed a typical long-day response type with a critical ...

Time measurement in insect photoperiodism: The role of photophase duration and light intensity

open access: yesEuropean Journal of Entomology, 2022
The initial stages of diapause induction - as summer gives way to autumn - involve a process of time measurement in which the duration of daylength (or nightlength) is determined by a photoperiodic 'clock' based upon the circadian system. In many insects

Ocean deoxygenation and copepods: coping with oxygen minimum zone variability [PDF]

open access: yesBiogeosciences, 2020
Increasing deoxygenation (loss of oxygen) of the ocean, including expansion of oxygen minimum zones (OMZs), is a potentially important consequence of global warming.

Some Effects of Photoperiod and Cold Storage on Oviposition of the Cereal Leaf Beetle Oulema Melanopus (Coleptera: Chrysomelidae) [PDF]

open access: yes, 2017
An expanded program of research on the cereal leaf beetle, Oulema melanopus (L.), in various north-central states has made it necessary to develop methods of rearing all stages of the beetle for laboratory use. Because the insect survives diapause in the

Pulse of inflammatory proteins in the pregnant uterus of European polecats (Mustela putorius) leading to the time of implantation [PDF]

open access: yes, 2017
Uterine secretory proteins protect the uterus and conceptuses against infection, facilitate implantation, control cellular damage resulting from implantation, and supply pre-implantation embryos with nutrients.

Crowd-sourced observations of a polyphagous moth reveal evidence of allochronic speciation varying along a latitudinal gradient.

open access: yesPLoS ONE, 2023
Allochronic speciation, where reproductive isolation between populations of a species is facilitated by a difference in reproductive timing, depends on abiotic factors such as seasonality and biotic factors such as diapause intensity.

The chloride channel cystic fibrosis transmembrane conductance regulator (CFTR) controls cellular quiescence by hyperpolarizing the cell membrane during diapause in the crustacean Artemia [PDF]

open access: yes, 2019
Cellular quiescence, a reversible state in which growth, proliferation, and other cellular activities are arrested, is important for self-renewal, differentiation, development, regeneration, and stress resistance.

Special Significance of Non-Drosophila Insects in Aging

open access: yesFrontiers in Cell and Developmental Biology, 2020
Aging is the leading risk factor of human chronic diseases. Understanding of aging process and mechanisms facilitates drug development and the prevention of aging-related diseases.

Role of water and moisture in diapause development (A review)

open access: yesEuropean Journal of Entomology, 2003
While observational studies led to the assumption that water or moisture (W/M) is a prerequisite for diapause development, the experimental research indicates rather the opposite: usually W/M is needed as late as for the post-diapause resumption of ...

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 ...
