TLDR
Glycerol concentrations were closely correlated with the changing supercooling points and haemolymph freezing points in both the naturally acclimatized and laboratory acclimated specimens and temperature preferences showed a positive correlation with changes in cold tolerance.About:

Principles of Insect Low Temperature Tolerance
TL;DR: Insects, more than any other eukaryotic taxon, have evolved not only to survive but to flourish in a wide variety of thermal environments.
Journal ArticleDOI
Meeting the energetic demands of insect diapause: nutrient storage and utilization.
TL;DR: It is provided evidence that interactions between nutrient storage and metabolism can influence the decision to enter diapause and determine how long to remain in diAPause, and several mechanisms that have the potential to contribute to Diapause-associated nutrient homeostasis are proposed.

10 – Hormonal Control of Diapause
TL;DR: This chapter briefly discusses hormonal control of diapause, an arrest in development accompanied by a major shutdown in metabolic activity that occurs at a specific stage for each species.

Principles of Insect Cold-Hardiness
TL;DR: The principles of insect cold-hardiness will be discussed under three main headings : (a) chilling and cold-acclimation, (b) avoidance of freezing by supercooling, and (c) freezing-tolerance.

The Biochemistry of Sugars and Polysaccharides in Insects
TL;DR: This chapter presents an investigation of the biochemistry of this animal group, which has in general lagged far behind that of micro-organisms on the one hand and vertebrate animals on the other.

Effects of glycerol on cold-hardiness in insects
TL;DR: Evidence gathered from various diapausing species showed that glycerol accumulated during the fall, and an increase in concentration was observed in eggs of one species at temperatures ranging from −5° to 20 °C.

Role of glycerol in the cold-hardening of bracon cephi (gahan)
TL;DR: Concentrations of glycerol as great as 5 molal are built up in larvae of Bracon cephi (Gahan) after hibernation begins in the fall, and are lost again in the spring, and is directly responsible for the cold-hardening of the larvae in two separate ways.
