“…The same is true of a continuous freezing exposure; larvae frozen at -5°C for 60h had noticeably higher expression of hsp70 compared with those supercooled at -5°C. Although Rinehart et al (Rinehart et al, 2006) and Lopez-Martinez et al (Lopez-Martinez et al, 2008) did not observe an increase in hsp70 mRNA in response to freezing, their samples were only taken after a brief (i.e. 0-2h) recovery period.…”

There was an error published in J. Exp. Biol. 214,[806][807][808][809][810][811][812][813][814] In calculating the metabolite levels (i.e. lipid, glycogen, trehalose, glucose and glycerol) and energy content values (Figs2 and 3), an incorrect correction factor was applied in the last step of the calculation. The correct metabolite and energy content values can be obtained by multiplying the values that appear in the manuscript by a factor of 2.

“…Although low levels of ROS are beneficial for cell signaling and induction of defense genes in insects (Kamata and Hirata 1999;Wang et al 2001), high levels of ROS under stressful conditions can lead to oxidative stress (Lopez-Martinez et al 2008), protein carbonylation, DNA/RNA oxidation and lipid peroxidation (LPO) (Matés 2000;Yang et al 2010), and then loss of cell function (Stadtman and Levine 2003) or cell death (Imlay 2003;Krishnan and Kodrík 2011). Insects, therefore, should have the ability to eliminate surplus ROS from cells and extracellular fluids (Krishnan et al 2007).…”

“…To maintain homeostasis and counteract LPO damage, organisms have an antioxidant defense system including many enzymatic and nonenzymatic scavengers. The enzymatic scavengers include superoxide dismutase (SOD), peroxiredoxin, glutathione reductase (GR), and catalase (CAT), and the nonenzymatic scavengers are glutathione (GSH), ascorbic acid, alphatocopherol (vitamin E), beta-carotene, and uric acid (Livingstone 2001;Wang et al 2001;Lopez-Martinez et al 2008;Yang et al 2010;Imlay 2003;Rajarapu et al 2011). When oxidative stress occurs in insects, these ROS scavengers play an important role in protecting cells, decreasing LPO, and repairing protein or DNA and RNA damage (Felton and Summers 1995;Jia et al 2011).…”

High temperature often induces oxidative stress and antioxidant response in insects. This phenomenon has been well documented under controlled laboratory conditions, but whether it happens under fluctuating field conditions is largely unknown. In this study, we used an invasive lace bug (Corythucha ciliata) as a model species to compare the effects of controlled thermal treatments (2 h at 33-43°C with 2°C intervals in the laboratory) and naturally fluctuating thermal conditions (08:00-14:00 at 2-h intervals (29.7-37.2°C) on a hot summer day in a field in Shanghai, China) on lipid peroxidation (malondialdehyde (MDA) was the marker) and anaerobic respiration (lactate dehydrogenase (LDH) was the marker), as well as superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), and glutathione reductase (GR). The results show that MDA concentration increased significantly in response to heat stresses with similar trend in the laboratory and field. LDH activities did not significantly vary across temperatures in the laboratory-exposed individuals, but they significantly increased by rising temperature in the field. The activities or concentrations of SOD, CAT, GSH, and GR all significantly increased with increasing temperature in the two populations. These findings indicate that high temperature induces oxidative stress, resulting in high anaerobic respiration and antioxidant defenses in C. ciliata under both the laboratory and field conditions, which likely provide a defense mechanism against oxidative damage due to the accumulation of ROS.

“…Many stressors generate oxidative stress in animals including: low and/or high temperature (Storey and Storey, 2010;An and Choi, 2010), freezing (Joanisse and Storey, 1998;Hermes-Lima and Storey, 1993;Hermes-Lima et al, 1998), dehydration (Franca et al, 2007;Clark et al, 2009;López-Martínez et al, 2009;Benoit, 2010;Rizzo et al, 2010), ultraviolet (López-Martínez et al, 2008;Meng et al, 2010) and gamma irradiation (Peng et al, 1986;Datkhile et al, 2009), anoxia-reperfusion (Hermes-Lima andStorey, 1996;Hermes-Lima et al, 1998;HermesLima et al, 2001) and hypoxia-reperfusion (Jamieson et al, 1986;Hermes-Lima et al, 2001). Stress from the accumulation of reactive oxygen species (ROS) and the resulting oxidative damage can have long-lasting effects on organismal performance, and organisms experience multiple bouts of oxidative stress throughout their lifetime, with some of these bouts involving simultaneous combinations of multiple stressors (Metcalfe and Alonso-Alvarez, 2010; Benoit et al, 2010;Teets et al, 2011;Marshall and Sinclair, 2011).…”

SUMMARYMost organisms are repeatedly exposed to oxidative stress from multiple sources throughout their lifetimes, potentially affecting all aspects of organismal performance. Here we test whether exposure to a conditioning bout of anoxia early in adulthood induces a hormetic response that confers resistance to oxidative stress and enhances male sexual performance later in life in the Caribbean fruit fly, Anastrepha suspensa. Anoxic conditioning of adults prior to emergence led to an increase in antioxidant capacity driven by mitochondrial superoxide dismutase and glutathione peroxidase. When exposed to gamma irradiation, a strong oxidative stressor, males that received anoxic conditioning had lower lipid and protein oxidative damage at sexual maturity. Anoxia conditioning led to greater male sexual competitiveness compared with unconditioned males when both were irradiated, although there was no effect of anoxia conditioning on mating competitiveness in unirradiated males. Anoxia also led to higher adult emergence rates and greater flight ability in irradiation-stressed flies while preserving sterility. Thus, hormetic treatments that increased antioxidant enzyme activity also improved male performance after irradiation, suggesting that antioxidant enzymes play an important role in mediating the relationship between oxidative stress and sexual selection. Furthermore, our work has important applied implications for the sterile insect technique (SIT), an environmentally friendly method of insect pest control where males are sterilized by irradiation and deployed in the field to disrupt pest populations via mating. We suggest that hormetic treatments specifically designed to enhance antioxidant activity may produce more sexually competitive sterile males, thus improving the efficacy and economy of SIT programs.
