“…The effects of TE stress become especially apparent if exposure occurs in the later stages of larval development (Knapp & Nedvěd, 2013; Zhang et al., 2015). Depending on the insect species, exposure to TE during the pupal stage may lead to increased or decreased longevity of the adults, reduced fecundity, or increased mortality (Chen et al., 2018; Zheng et al., 2017). Although insect pupae, like eggs, are immobile, late‐instar larvae will often find secluded space to pupate (e.g., hiding or burrowing into the soil).…”

There is increasing evidence that a mass extinction event is in its early stages across much of the biosphere (Ceballos et al., 2017; Dirzo et al., 2014; Pievani, 2014). Well-studied species (vascular plants, vertebrates) have lost as much as 60% of genetic diversity over the past 50 years alone (Ripple et al., 2017). Recent studies are reporting that terrestrial insect biomass and/or diversity are also declining in some re

“…In contrast, hormesis after mild stress can have beneficial effects on cells and organisms and ultimately can improve life-history traits by stimulating maintenance and repair pathways (Costantini, 2010;Rattan & Clark, 2005;Sarup et al, 2014). In some cases, thermal stress at the pupal stage has lasting, unidirectional effects on the growth rate (Kingsolver & Huey, 2008) or a trade-off between increased lifespan and heat resistance for a loss in overall fecundity (Zheng et al, 2017). In contrast, the hormetic effects of mild heat stress during pupal stage have enhanced adult fitness but not heat tolerance in this study.…”

“…Zhang et al, 2013). For example, a thermal stress of 30°C experienced at larval or pupal stages alters reproductive traits of adult diamondback moths (W. Zhang, Rudolf, et al, 2015) and mild pupal heat stress affects life-history traits in adult oriental fruit moth (Zheng et al, 2017). Nevertheless, the life cycle modularity hypothesis, and empirical data suggest that the modular life cycle (metamorphosis) of insects somewhat isolates different stages from injuries at earlier developmental stages (Potter et al, 2011;Xing et al, 2014).…”

In the last decade, unexpected high temperatures have been frequent in spring and early summer. Numerous studies have shown that such thermal stress has substantial effects on lifehistory traits that influence fitness of insects, but few have examined expression dynamics of heat shock proteins (Hsps) across developmental stages, especially as regards potential carry-over effects at the transcriptional level across metamorphosis. We exposed pupae of the oriental fruit moth ("OFM," Grapholita molesta Busck) to mild heat stress (38°C, 6 h) and then quantified expression patterns of six Hsps (Hsp90, 70, 60, 40, 21, and 11) from pupal through adult stages. Almost all Hsps showed a higher expression immediately after pupae were heat-stressed, but later dropped to normal levels after metamorphosis. Although upregulation of Hsps is transient and the effects carry over longer to early adult stage, upregulation will nonetheless have positive effects on adult fitness. The fitness of some insects may benefit from higher expression of chaperon genes after mild stress, in the form of higher fecundity and longer lifespan, as a carry-over effect. These results suggest that mild thermal stress can change genetic expression that later boosts adult fitness through a cascade effect.

“…Thermal stress in one life stage can affect fitness in later stages in ectotherms with complex life cycles (Zhang et al, 2015; Zheng et al, 2017; Chen et al, 2018c). To our knowledge, many studies have focused on the effects of extreme events on the treated life stage but seldom involve carry-over effects on subsequent stages.…”

Physiological Metabolic Responses of Ophraella communa to High Temperature Stress

Considering the predicted rising temperatures under current climate change and heat wave scenarios, organisms are expected to suffer more intense and frequent thermal stress. Induced heat is accumulated by organisms and can cause a variety of physiological stress responses. Ophraella communa is an effective biological control agent of common ragweed, Ambrosia artemisiifolia , but the responses of this biocontrol agent to heat stress have not been fully elucidated and, therefore, its potential responses to climate change are uncertain. We investigated the physiological metabolism of subsequent O. communa adults after: (1) different developmental stages (egg, larval, pupal, and adult) were exposed to thermal stress for 3 h each day for 3, 5, 5, and 5 days, respectively (by stage); and (2) individuals were exposed to thermal stress throughout the egg-to-adult period for 3 h each day. The high temperatures of 40, 42, and 44°C were used to induce thermal stress. A control group was reared at 28 ± 2°C. The results showed that short- or long-term exposure to daily phasic high temperatures significantly decreased water and lipid contents and significantly increased glycogen and glycerol contents in all adults (i.e., after exposure of different stages or throughout the egg-to-adult period). However, the total sugar content significantly increased in adults after the eggs and larvae were exposed to brief short-term thermal stress. Compared to the control, the total sugar content was also significantly higher in the adults and pupae exposed to 44°C. Total sugar content in females increased significantly in response to long-term phasic thermal stress at 40°C. However, sugar content of males exposed to 44°C decreased significantly. After long-term phasic thermal stress, water and glycogen contents in males were significantly higher than in females; however, females had higher total sugar and lipid contents. Therefore, our study provides a basic understanding of the metabolic responses of O. communa to thermal stress and offers insights into its potential as a natural biocontrol agent against A. artemisiifolia during the summer season and under predicted climate change scenarios.
