“…Most authors currently choose cooling rates that compromise between ecological relevance and time investment; generally 0.1 to 0.5 °C/min (e.g. Boardman et al, 2012;Crosthwaite et al, 2011;Renault et al, 2004;Sformo et al, 2011). It is clear that the rate of temperature change does affect the response of the insect (this has also been vigorously discussed in the context of high temperature tolerances, e.g.…”

“…For example, prepupae of the emerald ash borer, Agrilus planipennis can survive prolonged exposures to subzero temperatures, provided they do not freeze, and in the winter have SCPs below -25 °C (Crosthwaite et al, 2011). Cryoprotective dehydration is a special case of freeze avoidance, whereby ice formation is prevented via removal of freezable water to environmental ice through a permeable cuticle.…”

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.

“…To study the full scope of the invasion and to avoid introducing any bias in parameter estimates, we take the interval range of r to be (30, 200) and the point estimate to be the observed mean value r = 70. Crosthwaite et al (2011) recently published a detailed study of the overwintering physiology of the EAB. Their study focused on determining how sensitive larval survival is to cold temperatures and the supercooling point, the point at which larvae freeze to death.…”

In this dissertation, we study integrodifference equations in patchy landscapes. Specifically, we provide a framework for linking individual dispersal behavior with populationlevel dynamics in patchy landscapes by integrating recent advances in modeling dispersal into an integrodifference equation.First, we formulate a random-walk model in a patchy landscape with patchdependent diffusion, settling, and mortality rates. We incorporate mechanisms for individual behavior at an interface which, in general, results in the probability-density function of the random walker being discontinuous at an interface. We show that the dispersal kernel can be characterized as the Green's function of a second-order differential operator and illustrate the kind of (discontinuous) dispersal kernels that arise from our approach. We examine the dependence of obtained kernels on model parameters.Secondly, we analyze integrodifference equations in patchy landscapes equipped with discontinuous kernels. We obtain explicit formulae for the critical-domain-size problem, as well as explicit formulae for the analogous critical size of good patches on an infinite, periodic, patchy landscape. We examine the dependence of obtained formulae on individual behavior at an interface. Through numerical simulations, we observe that, if the population can persist on an infinite, periodic, patchy landscape, its spatial profile can evolve into a discontinuous traveling periodic wave. We derive a dispersion relation for the speed of the wave and illustrate how interface behavior ii

Gomphocerus sibiricus L., the dominant insect species in the alpine and subalpine grassland, overwinters with diapause at egg stage. In this study, cold tolerance and related cryoprotectants of G. sibiricus eggs were investigated. In particular, the supercooling point (SCP), water content, carbohydrates (trehalose, glucose, fructose, glycogen), polyols (glycerol, inositol, sorbitol), fat, and amino acids contents were evaluated at different developmental stages of G. sibiricus eggs collected under natural conditions. The SCPs of eggs were very low (−32.83 to −22.61°C) at middiapause. Water content gradually increased during development. The fructose, glycerol, and sorbitol contents were significantly higher in diapausing eggs than in early embryogenesis stage and post-diapause development stage.Glycogen content was high throughout the whole developmental period. The trehalose, glucose, and inositol contents were low during diapause compared to that in early embryogenesis stage and post-diapause development stage. There were no significant differences in the fat content of eggs among all development stages. The total amino acid contents in eggs in the early embryogenesis and at the start of diapause were higher than that in
