“…In contrast, other studies, including this one, have not found a correlation between feeding/starvation and nucleation (2). Most insects empty their gut within 1-2 days after food is removed.…”

“…The supercooling point (SCP) is defined as the temperature at which body water spontaneously freezes, For freeze-intolerant insects it represents the absolute limit of low temperature tolerance, although some insects experience cold shock injury and death at temperatures above the SCP (2,12,13). Frequently, insects exhibit a seasonal pattern in their capacity to supercool: SCPs decrease through the autumn reaching their lowest values in winter followed by a reduction in their supercooling capacity in the spring (19).…”

“…Our previous work with flesh flies demonstrated that only pupae in mid-diapause are capable of surviving temperatures near the supercooling point . Several other studies have recently cautioned against using the supercooling point as an indicator of cold tolerance (Bale 1987;Bennett and Lee 1989;Lee and Denlinger 1985).…”

“…Additionally, changes in the SCP with treatment (Coleman et al, 2014). Because the SCP does not necessarily equate to cold-hardiness, it must be interpreted with caution, and in many cases has limited ecological relevance (Bale, 1987;Baust and Rojas, 1985;Renault et al, 2002).…”

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.
