Ecological and physiological aspects of aestivation-diapause in the larvae of two Pyralid stalk borers of maize in Kenya [PDF]
, 1978 Stalk borers are highly destructive to a large number of important graminaceous crops all over the world. Some examples of economically important stalk borers and a general description of their life-cycle are mentioned in chapter 1.

Juvenile Hormone III but Not 20-Hydroxyecdysone Regulates the Embryonic Diapause of Aedes albopictus
Frontiers in Physiology, 2019 Diapause is an alternative developmental trajectory allowing insects to enter dormancy and persist through predictable periods of seasonally unfavorable conditions.

American Journal of Botany, EarlyView.Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Ecophysiological studies on invertebrate diapause [PDF]
, 1997 Diapause performs two main functions in the life-cycle of an insect. In addition to protecting the organism from adverse seasonal conditions it synchronises active stages of development with optimal conditions for growth.

PLoS ONE, 2015 The northernmost Harbin strain (N strain) of the Asian corn borer, Ostrinia furnacalis enters facultative diapause as fully grown larvae in response to short daylengths; whereas the southernmost Ledong strain (S strain) exhibits almost no diapause under ...

Future warming enhances rates of population increase of arthropod crop pests globally
Ecography, EarlyView.Arthropod herbivores cause severe crop yield losses worldwide. Global warming is expected to shift their ranges, phenologies and performances, highlighting the need for improved forecasts of their potential expansion and impacts on food security. After decades of experimental research on thermal biology of arthropod crop pests, available data and tools

Calanus finmarchicus seasonal cycle and diapause in relation to gene expression, physiology, and endogenous clocks [PDF]
, 2018 The copepod Calanus finmarchicus plays a crucial role in the north Atlantic food web. Its seasonal life cycle involves reproduction and development in surface waters before overwintering in diapause at depth. Although diapause has been studied for more

Ecography, EarlyView.As extreme climatic events are becoming more frequent, we need to understand what mechanisms could buffer populations to ensure their persistence. Fragmented populations may be especially vulnerable, as exemplified by species with metapopulation dynamics whose persistence is determined by a precarious balance between frequent local extinctions and ...

eLifeThe effects of environmental stress on animal life are gaining importance with climate change. Diapause is a dormancy program that occurs in response to an adverse environment, followed by resumption of development and reproduction upon the return of ...

European Journal of Entomology, 2008 Effect of pre-diapause temperature on summer and winter diapause intensity was examined under both laboratory and field conditions. Under short photoperiods of 8L : 16D and 10L : 14D, all pupae entered diapause at 15, 18 and 20°C and the incidence of ...
