Insects in agroecosystems contend with many stressors–eg, chemicals, heat, nutrient
deprivation–that are often encountered at low levels. Exposure to mild stress is now well …

Hormesis in aging is represented by mild stress-induced stimulation of protective
mechanisms in cells and organisms resulting in biologically beneficial effects. Single or …

Epidemiologic studies have consistently shown that sleeping> 8 h per night is associated
with increased mortality. Indeed, the most recent American Cancer Society data of 1.1 …

Ecology Letters (2010) 13: 1435–1447 Abstract There is increasing evidence that some non‐
essential substances or environmental stressors can have stimulatory or beneficial effects at …

The fruit fly Drosophila melanogaster is one of the principal model organisms used for
studying the biology of aging. Flies are well suited for such studies for a number of reasons …

Heat shock proteins (Hsp) are involved in protein folding, transport and stress resistance.
Studies reporting an increased mRNA level of hsp genes in aged Drosophila suggest that …

The biphasic hormetic response to stress, defined by low-dose stimulation and high-dose
inhibition is frequently observed in insects. Various molecular and biochemical responses …

We assessed the impact of repeated episodes of a mild heat stress on lifespan, fecundity,
heat stress resistance and Hsp70 expression in Drosophila melanogaster. There was a …

Since their discovery in Drosophila, the heat shock proteins (Hsps) have been shown to
regulate both stress resistance and life-span. Aging is characterized by increased oxidative …

The term hormesis was coined to describe a phenomenon where exposure to high levels of
stressors is inhibitory whereas low (mild, sublethal, and subtoxic) doses are stimulatory. The …
