Eastern Pine Seedworm, \u3ci\u3eCydia Toreuta\u3c/i\u3e (Lepidoptera: Tortricidae) in Red Pine Cones in Wisconsin [PDF]

open access: yes, 2017
Cydia toreuta population densities, prolonged diapause behavior, parasitism and adult emergence patterns were examined over four years at two red pine locations in Wisconsin. Last-instar densities ranged from 0.54 to 3.18 per cone.

Temperature-Dependent Development of the Post-Diapause Periods of the Apricot Seed Wasp Eurytoma maslovskii (Hymenoptera: Eurytomidae): An Implication for Spring Emergence Prediction Models

open access: yesInsects, 2022
The present study investigates the influence of temperature on the development of Eurytoma maslovskii after a diapause break up until adulthood. The insect development rate was fitted to both linear and nonlinear models to estimate thermal bioparameters,

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.

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.

Photoperiodic control of the intensity of diapause and diapause development in the bean bug, Riptortus clavatus (Heteroptera: Alydidae)

open access: yesEuropean Journal of Entomology, 2000
Adult diapause in Riptortus clavatus (Thunberg) was induced by short-day photoperiods, and the critical daylength for its induction was 13.5 h. When insects were reared from eggs under diapause-inducing photoperiods near the critical daylength, the ...

Synchronisation of egg hatching of brown hairstreak (Thecla betulae) and budburst of blackthorn (Prunus spinosa) in a warmer future [PDF]

open access: yes, 2010
Synchronisation of the phenology of insect herbivores and their larval food plant is essential for the herbivores’ fitness. The monophagous brown hairstreak (Thecla betulae) lays its eggs during summer, hibernates as an egg, and hatches in April or May ...

Relationship between the natural duration of diapause and post-diapause reproduction in the cabbage beetle, Colaphellus bowringi (Coleoptera: Chrysomelidae)

open access: yesEuropean Journal of Entomology, 2010
The cabbage beetle, Colaphellus bowringi Baly undergoes an imaginal summer and winter diapause in the soil; adult emergence is spread over several months to more than 2 years, with prolonged diapause occurring in certain adults under natural conditions ...

Life history patterns of Procladius choreus, Tanypus punctipennis and Chironomus balatonicus in Lake Balaton [PDF]

open access: yes, 2008
Life history patterns of the three most abundant chironomids were analysed in Lake Balaton by monitoring the population dynamics of larvae and the presence of pupal exuviae.

Ecophysiological consequences of variability in diapause intensity

open access: yesEuropean Journal of Entomology, 2002
Diapause intensity (DI) is a physiological trait represented by the duration of diapause under given conditions of environment. In many species, it is highly variable, probably being controlled by multiple genes and tends to form a cline in response to ...

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.
