Temperature directly affects survival, development and reproduction in insects and thereby it is a key environmental driver for geographic distribution and population dynamics. This study aims at testing the survival of Drosophila melanogaster under constant low temperatures (CLTs) (2, 3, 4, and 5°C) vs. fluctuating thermal regimes (FTRs). In the latter, the cold stress period was interrupted daily by 2 h pulses at 20°C. Since acclimation enhances cold tolerance, we tested whether benefits of…

Effects of fluctuating thermal regimes on cold survival and life history traits of the spotted wing Drosophila (Drosophila suzukii)

Detailed information is provided on the application and optimization of an FTR‐based protocol for cold storage of D. suzukii that could be useful for the biocontrol of this pest.

Warm periods in repeated cold stresses protect Drosophila against ionoregulatory collapse, chilling injury, and reproductive deficits

It was found that warm periods in general improved survival outcomes, and individuals that recovered for more time in between cold periods had significantly lower rates of injury, faster recovery from chill coma, and produced greater, rather than fewer, offspring.

Mechanisms underpinning the beneficial effects of fluctuating thermal regimes in insect cold tolerance

FTR definitively enhances survival at low temperature in insects, but before it can be widely used, it is suggested that the possible fitness and energy costs of FTR must be explored more thoroughly.

Transgenerational and within‐generation plasticity shape thermal performance curves

It is found that both, environmental thermal variability and high temperature experienced during early ontogeny shaped the fruit fly TPC sensitivity, and since TPC parameters are not fixed, cautiousness is suggested when using TPCs to predict the impact of climate change on natural populations.

Effects of Acclimation, Population, and Sex on Behavioral Thermoregulation, CTMax, Symptoms of Heat Stress, and Gene Expression of Melanoplus differentialis, a Generalist Grasshopper—Does Temporal Thermal Heterogeneity Prepare Populations for a Warming World?

It is concluded that thermal heterogeneity may play a selective role in some, but not all, of the measured thermoregulatory traits and their plasticity.

Rapid Adjustments in Thermal Tolerance and the Metabolome to Daily Environmental Changes – A Field Study on the Arctic Seed Bug Nysius groenlandicus

Laboratory investigations on terrestrial model-species, typically of temperate origin, have demonstrated that terrestrial ectotherms can cope with daily temperature variations through rapid hardening

Mortality from desiccation contributes to a genotype–temperature interaction for cold survival in Drosophila melanogaster

Results support the conclusion that in D. melanogaster there are multiple physiological mechanisms of cold-induced mortality across relatively small differences in temperature, and that desiccation contributes to mortality for exposures near 6°C but not for subzero temperatures.

Effect of Prolonged Coldness on Survival and Fertility of Drosophila melanogaster

Results show that the 2-week maintenance interval of stocks of D. melanogaster can be extended 3–7 fold, at least for 1 generation, by storing adult flies at 11°C.

Comparing phenotypic effects and molecular correlates of developmental, gradual and rapid cold acclimation responses in Drosophila melanogaster

A comprehensive assessment of how the different forms of acclimation based on simulated field temperatures affect cold tolerance in Drosophila melanogaster under different levels of cold stress concludes that combined acclimated treatments may strongly impact field stress resistance.

Costs and benefits of cold acclimation in field-released Drosophila

Although physiological acclimation may dramatically improve fitness over a narrow set of thermal conditions, it may have the opposite effect once conditions extend outside this range, an increasingly likely scenario as temperature variability increases under global climate change.

A nonlethal technique for rapidly quantifying the cold tolerance of large numbers of Drosophila and other small insects is modified and applied and potentially can be used in selection experiments.

It is suggested that the transfer to 20 °C allows a re‐activation of the normal metabolism, leading to repair and recovery of any injuries caused by prolonged chilling, underlines the importance of cyclic temperature changes on insect survival.
