“…On the other hand, in species having diapause ability, the SCPs were not significantly different between diapause and non-diapause individuals (Broufas and Koveos, 2001a;Morewood, 1992; Tables 2 and 3). In most mites and insects with tiny body sizes, the SCPs range from −15 to −30°C (Lee, 1991;Sømme, 1982) even in the species that have a diapause ability. The mean SCPs obtained from phytoseiid mites were similar to each other and were around −20°C with a slight variation (Table 3).…”

Mites of the genus Neoseiulus are predatory mites that feed on pest species such as the two-spotted spider mite (Tetranychus urticae) and therefore act as biocontrol agents. Since the 1990s, the population of N. californicus in central and southwestern Japan has increased sharply, replacing the native N. womersleyi in many orchards in this area. However, in orchards of northern Japan, N. californicus is much less abundant than N. womersleyi. Here we tested the hypothesis that the lower abundance of N. californicus in the north is due to a lack of cold hardiness. The mean supercooling points of adult females of two strains of N. californicus (an indigenous strain and a commercial strain, neither of which enters diapause) and diapause and non-diapause N. womersleyi were all in the range −21.9~−23.3°C and were not significantly different. However, more than 50% of diapause females of N. womersleyi survived for more than 7 days exposed to −5°C, while most females of the non-diapause N. womersleyi and the two N. californicus strains died after 3-5 days of exposure to −5°C. Exposure of adult females to −5°C for various periods did not significantly affect subsequent fecundity and egg viability. These results suggest that the lower cold hardiness of N. californicus might be one of the factors halting its northern advance, but it is probably not sufficient to be the only factor.

“…For example, springtails that have recently fed (introducing ice nucleators into the gut leading to a high group of SCPs; Sømme, 1982), and/or moulted (removing nucleators; Worland et al, 2006) have very different SCPs. Starved adult Alphitobius diaperinus beetles also had a bimodal SCP distribution, but this was due to s starvation × sex interaction such that the SCPs of males decreased with starvation, but the SCps of females did not (Salin et al, 2000).…”

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.
