“…Bale et al, 1989;Cloudsley-Thompson, 1973;Miller, 1978). In particular, directly plunging an insect into an extreme temperature can significantly decrease survivorship, compared to that achieved during a ramping regime (Nguyen et al, 2014).…”

“…Third, some species may switch strategy entirely. For example, overwintering larvae of the beetle Dendroides canadensis, (Coleoptera: Pyrochroidae) switched from freeze tolerant in the winter of 1978-1979to freeze avoidant in 1981-1982(Horwath and Duman, 1984. We will discuss approaches to elicit this plasticity in Section 6.…”

Insect performance is limited by the temperature of the environment, and in temperate, polar, and alpine regions, the majority of insects must face the challenge of exposure to low temperatures. The physiological response to cold exposure shapes the ability of insects to survive and thrive in these environments, and can be measured, without great technical difficulty, for both basic and applied research. For example, understanding insect cold tolerance allows us to predict the establishment and spread of insect pests and biological control agents. Additionally, the discipline provides the tools for drawing physiological comparisons among groups in wider studies that may not be focused primarily on the ability of insects to survive the cold. Thus, the study of insect cold tolerance is of a broad interest, and several reviews have addressed the theories and advances in the field. Here, however, we aim to clarify and provide rationale for common practices used to study cold tolerance, as a starter's guide for newcomers to the field, students, and those wishing to incorporate cold tolerance into a broader study. We cover the 'tried and true' measures of insect cold tolerance, the equipment necessary for these measurement, and summarize the ecological and biological significance of each. Additionally, we provide a suggested framework and workflow for measuring cold tolerance and low temperature performance in insects.

“…Conversely, other studies document that ramping assays are valid and ecologically relevant for assessing insect thermal tolerance (Terblanche et al, 2011;Overgaard et al, 2012). Positive relationships between cooling rate and mortality in larval and adult stages are documented for several insect species (Salt, 1966;Miller, 1978;Kelty & Lee, 2001;Overgaard et al, 2012).…”

Abstract. This study was carried out to investigate the effects of cold acclimation, cooling rate and heat stress on supercooling capacity and cold hardiness of the potato tuber moth (PTM), Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae). Supercooling points (SCP) of first and last instar larvae, prepupae and pupae were -21.8, -16.9, -18.9 and -18.0°C, respectively. Cold acclimation (1-week at 0 and 5°C) did not affect SCPs of acclimated last instar larvae, prepupae and pupae. LT 50 s (lower lethal temperature for 50% mortality) for first and last instar larvae, prepupae and pupae were -15.5, -12.4, -17.9 and -16.0°C, respectively. Cold acclimation resulted in a significant decrease in mortality of all developmental stages. In addition, the mortality rates of the different developmental stages decreased with decrease in cooling rate. In addition, heat hardening (kept at 40°C for 2 h) significantly reduced mortality of all developmental stages exposed to LT 50 conditions, suggesting that heat hardening also affects cold tolerance. Results indicate that none of the stages could tolerate subzero temperatures below their SCPs, indicating that this species might be a chill tolerant insect. These adaptive responses may allow PTM to enhance its cold tolerance and colonize cold regions.

“…For example, Gillyboeuf et al (1994) suggested that differences in the SCP between two populations of pink maize stalk borer, Sesamia nonagrioides Let, were due to the amounts of INAs in the two corn cultivars the borers fed on. Acclimation to low temperature has resulted in both increased (Tursman et al 1994, Gehrken and Southon 1996, Sinclair 1997) and decreased (Ramlov et al 1992, Worland et al 1998) SCPs while others found no effect (Miller 1978, Gillyboeuf et al 1994, Kim and Kim 1997. Davis and Kamble (1994) observed lower SCPs in R. flavipes workers acclimated at 10°C for 30 d and then exposed to 0°C for 30 d than in workers acclimated for shorter periods.…”

Supercooling points were determined for untreated field-collected and untreated laboratory-maintained Reticulitermes flavipes (Kollar) workers and soldiers. Workers treated with antibiotics or had their hindgut-protozoa removed by exposing them to oxygen under pressure to determine the effects of absence of the hindgut fauna on supercooling. Supercooling points were compared between live and freshly-killed workers to determine whether supercooling in this species might be simply due to the biochemical properties of body fluids. Laboratory-maintained workers were also subjected to desiccation, starvation, or atmospheric pressure to determine their effects on supercooling. Supercooling points were lowest for laboratory workers treated with antibiotics and those that fed on brown paper-toweling for 7 d. Untreated field-collected workers had significantly higher supercooling points than untreated laboratory-maintained workers (−6.06 ± 0.79°C vs −9.29 ± 2.38°C, P < 0.0001). Both untreated field-collected and laboratory soldiers had significantly lower supercooling points than their respective workers (−7.39 ± 2.01°C vs −6.06 ± 0.79°C, P < 0.0001; and −11.60 ± 2.53°C vs −9.29 ± 2.38°C, P< 0.0001, respectively). There was no significant association between termite body mass and supercooling points for both laboratory and field termites (P= 0.0523 and P = 0.6242) or water content of laboratory termites and supercooling points (P = 0.1425). Defaunated workers had significantly lower supercooling points (−10.34 ± 2.38°C) than normally faunated workers (−9.48 ± 1.85°C)(P= 0.0095) suggesting that the symbiotic fauna may have higher supercooling points and act as ice nucleators in the termite hindgut. Starved and desiccated workers had significantly lower supercooling points (−10.38 ± 2.70°C and −10.39 ± 2.38°C, respectively) than their corresponding control groups (−9.87 ± 2.11°C and −9.89 ± 1.94°C; P = 0.0454; P = 0.0234, respectively) and untreated workers (−9.29 ± 2.38°C; P= 0.0021; P= 0.0011) suggesting that some forms of physical stress might lower the supercooling point.
