“…2 Insects, as a form of adaptability, have lower and upper thermal limits, from which survival does not occur outside this range (Garcia and Parra 2021;Pereira, Diniz, and Parra 2023). Through the parameters evaluated in our research, it was evident that for S. eridania the upper thermal limit is 35 ºC, the same was found by other authors (Park et al 2015;Maharjan et al 2017;Zhu et al 2017;Paes et al 2018;Lacerda et al 2019;Waghmare et al 2021). This fact may be related to the fact that at high temperatures the metabolic processes of insects increase, and thus their development time is reduced, however, at low temperatures these processes decrease, which prolongs the insect's development time (Martins et al 2016;Marchioro and Foerster 2011).…”

Objective: This work aimed to study the biological aspects of Spodoptera eridania, reared at different temperatures; and fed artificial and natural diets. Methods: In climatic chambers, the insects were subjected to six constant temperatures (15, 19, 23, 27, 31, and 35 °C). At all temperatures, both types of diet were offered to obtain data on cycle duration, viability, and total oviposition. Results and Conclusion: The different temperatures and diets influenced the insect development stages and the egg-adult cycle. The development of S. eridania is inversely proportional to the increase in temperature. Research Implications: The study confirmed differences in insect development in different diet sources and at different temperatures, and can be applied to S. eridania breeding techniques in research laboratories. Originality/Value: This research contributes by exploring the developmental biology of the pest organism, and can be used in research laboratory methodologies for pest breeding and commercialization for studies of more sustainable agricultural practices.

“…Metabolomic analysis provides good prospects in the search for new biomarkers of winter hardiness, that can enhance our understanding of energy balance, metabolic changes, and biological functions of endogenous metabolites [ 29 – 31 ]. A metabolomics approach has been used previously to analyze metabolic changes that support overwintering in several species including thirteen-lined ground squirrels ( Ictidomys tridecemlineatus ) [ 32 – 34 ], Syrian hamsters ( Mesocricetus auratus ) [ 35 ], common cutworms ( Spodoptera litura ) [ 30 ], and wolf spiders ( Schizocosa stridulans ) [ 31 ] but, to date, has not been applied to overwintering by amphibians or reptiles. The present study provides the first metabolomics analysis of a frog species, the Xizang plateau frog, Nanorana parkeri (Anura, Dicroglossidae), that lives in one of the most extreme environments on Earth, the Qinghai-Tibet Plateau.…”

Many animals lower their metabolic rate in response to low temperatures and scarcity of food in the winter in phenomena called hibernation or overwintering. Living at high altitude on the Tibetan Plateau where winters are very cold, the frog Nanorana parkeri, survives in one of the most hostile environments on Earth but, to date, relatively little is known about the biochemical and physiological adjustments for overwintering by this species. The present study profiled changes in plasma metabolites of N. parkeri between winter and summer using UHPLC-QE-MS non-target metabolomics in order to explore metabolic adaptations that support winter survival. The analysis showed that, in total, 11 metabolites accumulated and 95 were reduced in overwintering frogs compared with summer-active animals. Metabolites that increased included some that may have antioxidant functions (canthaxanthin, galactinol), act as a metabolic inhibitor (mono-ethylhexylphthalate), or accumulate as a product of anaerobic metabolism (lactate). Most other metabolites in plasma showed reduced levels in winter and were generally involved in energy metabolism including 11 amino acids (proline, isoleucine, leucine, valine, phenylalanine, tyrosine, arginine, tryptophan, methionine, threonine and histidine) and 4 carbohydrates (glucose, citrate, succinate, and malate). Pathway analysis indicated that aminoacyl-tRNA biosynthesis, phenylalanine, tyrosine and tryptophan biosynthesis, and nitrogen metabolism were potentially the most prominently altered pathways in overwintering frogs. Changes to these pathways are likely due to fasting and global metabolic depression in overwintering frogs. Concentrations of glucose and urea, commonly used as cryoprotectants by amphibians that winter on land, were significantly reduced during underwater hibernation in N. parkeri. In conclusion, winter survival of the high-altitude frog, N. parkeri was accompanied by substantial changes in metabolomic profiles and this study provides valuable information towards understanding the special adaptive mechanisms of N. parkeri to winter stresses.

“…Therefore, insects must regulate their metabolism against freezing (Tian et al, 2016;Colinet et al, 2017). Adaptation to cold stress in insects is normally based on the activation of the main metabolic pathways (Zhu et al, 2017), the accumulation of carbohydrates, polyols, and free amino acids in the hemolymph (Rozsypal et al, 2013), and the synthesis of various proteins. Cold hardy insects have been widely studied for their protective strategies of tolerance to low temperatures.…”

The Chinese white pine beetle, Dendroctonus armandi Tsai & Li (Coleoptera: Curculionidae, Scolytinae), is considered the most destructive forest pest in the Qinling and Bashan Mountains of China. In recent years, winter temperature has dropped in these regions, and extremely low temperatures are hard to survive for insects. Cold hardiness becomes a crucial strategy because temperature change often leads to fluctuations in insect abundance, and the metabolism rate is a key index of resistance to cold in overwintering insects. Therefore, we investigated the relationship between the change in respiratory rate and the activity of metabolism-related mitochondrial enzymes in D. armandi larvae under cold conditions. We found that the respiratory rate decreased, and it was matched with the activity of glutamate dehydrogenase, aconitase, and lipase during overwintering. Among the various test times under cold conditions, the respiratory rate also decreased with decreasing temperature and increased under very low temperatures. At all cold stress periods, glutamate dehydrogenase and lipase showed increased activity at higher temperatures and decreased activity under lower temperatures, but the activity of NAD-malic enzyme, NADP-malic enzyme, mitochondrial isocitrate dehydrogenase, and aconitase were contrary. Under all low temperatures, the activity of enzymesexcept for NADP-malic enzyme, glutamate dehydrogenase, and lipaseincreased in short-term cold stress and decreased in long-term cold stress at 4, 0, −4, −6, −8, and −10°C. However, at −2°C, the activity of enzymes showed a decreasing trend in short-term treatments and an increasing trend in long-term treatments, except for mitochondrial isocitrate dehydrogenase. The results not only improve our understanding of the metabolic mechanism of cold adaptation in D. armandi, but also provide an important experimental basis for further study and biological pest control.
