“…We found indeed that thermoperiodic cold acclimation was associated with a reduction of glycolytic (glycerate) and TCA cycle intermediates (citrate, fumarate and malate). A reduction of energy metabolism after cold acclimation is considered as an adaptive energy‐saving strategy (Lee 1980; Evans 1981). In Dendrolimus tabulaeformis , cold hardiness is promoted via an accumulation of sugars concomitant with a metabolic depression after cold acclimation (Zeng et al.…”

Summary 1. Adaptive responses to thermal stress typically involve a range of plastic acclimatory responses in ectothermic animals. The mechanisms underlying phenotypic plasticity in inducible cold tolerance are complex and not fully understood. 2. Here we investigated how thermoperiodic cold acclimation affected the cold tolerance and the metabolome of adult Drosophila melanogaster. We have used targeted GC/MS metabolomic profiling to address whether cold acclimation induced specific metabolic changes and affected the dynamics of the homeostatic response following different types of cold stress (acute and chronic). 3. Developmental combined with gradual adult acclimation strongly promoted cold tolerance. This phenotypic variation was associated with significant metabolic changes, among which some sugars, polyamines and metabolic intermediates are fingerprints of these changes. Cold acclimation allowed individuals to maintain metabolic homeostasis, whereas non‐acclimated counterparts suffered from deep and persistent homeostatic perturbations. 4. This study gives a fertile ground for future research in disentangling the role of several metabolites putatively involved in cold acclimation and cold stress response. It also provides insight into the mechanisms by which cold acclimation is achieved in D. melanogaster and gives a basis for elucidating the evolution of plastic responses to thermal variations.

“…5), although the main peak flight at Letellier did not occur until September. n = 4 , unpublished 1991 data from farms in southern Manitoba) were too cold to allow the movement of R. dominica for which the chill coma is 6.5"C (Evans 1981). Rhyzopertha dominica may originate from isolated grain stores that do not cool enough to prevent overwintering, such as inside feed mills, large unventilated grain bins, or grain that is heating due to mould or insect growth (Sinha and Wallace 1965;1966).…”

Rhyzopertha dominica (F.) (lesser grain borer, Coleoptera: Bostrichidae) is a major pest of stored grain in the United States, Australia, and most other warm regions of the world. It has rarely been detected in Canadian grain, until recently. To determine the distribution of/R. dominica in western Canada, Lindgren multiple-funnel traps baited with R. dominica aggregation pheromones were placed near grain elevators, feed mills, and farms. Rhyzopertha dominica was found flying outside grain-handling facilities in all Prairie Provinces in 1990 and 1991, with thousands collected in Manitoba, hundreds in Alberta, and less than 100 in Saskatchewan. A few R. dominica were caught in Vancouver and Thunder Bay. None were caught in the traps placed beside two grain elevators in southern Ontario. In Alberta and Saskatchewan, the locations with R. dominica were mainly in the south. In Manitoba, the total number of R. dominica caught at each location was higher in the south than in the north. Rhyzopertha dominica were caught as early as 15 May and as late as 18 September, with the peak numbers for a given location occurring between July and September. No difference in the total number of R. dominica caught per year was found among farms, feed mills, or grain elevators in 1990 or 1991. Sampling of stored grain on three farms showed that two of the eight bins sampled had R. dominica. The possible origins of the R. dominica (importation of infested grain, wind-borne migration from the United States, or an established Canadian population) are discussed.

“…In cold-acclimated C. ferrugineus, trehalose and amino acids including proline, asparagine, valine, lysine, leucine, isoleucine, alanine, phenyl alanine, glutamic acid, and aspartic acid, as well as phosphoethanolamine (a phospholipid precursor), were higher than in unacclimated C. ferrugineus [136]. Furthermore, the acclimation increased the mean fresh weights of C. ferrugineus [137]. The acclimation temperature was found to affect the behavior of C. ferrugineus more than the exposure time [138].…”

Cryptolestes ferrugineus, the rusty grain beetle, is a cosmopolitan pest that has adapted to cool and warm climates due to its unique biology, ecology, and behavior. The rusty grain beetle is a pest of high economic importance; hence, understanding their biology, ecology, and behavior could be useful in designing effective management strategies. An extensive literature survey was conducted using the databases Web of Science and Scopus. Information on country-wise publications from 1949 to 2023 on C. ferrugineus was provided, and a table illustrating the distribution of C. ferrugineus was also presented to demonstrate the global significance of C. ferrugineus. We overviewed their life stages, morphology, and factors influencing their biology, ecology, and behavior, such as refuge-seeking behavior, flight activity, mating behavior, interspecific interaction with other species, movement, and distribution. Mathematical models focusing on C. ferrugineus population dynamics and movement were also presented. In order to advance our knowledge on C. ferrugineus, the following possible avenues for future research were outlined: application of molecular markers and population genetic approaches to understand their evolutionary history; mechanisms responsible for adaptation and resistance to insecticide; interspecific interaction in storage facilities and wider landscapes; and identification of microbial roles in the ecology, behavior, and control of C. ferrugineus.
