“…According to Arthur, Hartzer, Throne, and Flinn (2017), separate protocols should be developed for each stored product insect species, if low‐temperature treatment at –18 °C is used as a disinfestation technique. Cold hardiness can be developed in insects when they are exposed to low temperatures, which can hinder the technique of pest control (Andreadis & Athanassiou, 2017). The design of extreme temperature treatments depends on several biotic and abiotic conditions, which makes it a difficult task to use for pest management in grains and grain products (Athanassiou et al., 2018; El‐Syrafi et al., 2010).…”

Management of stored product insects is a major concern and widely researched topic in the food and grain processing and storage industry. In the scenario of estimated utilization of produces exceeding the production, postharvest losses should be properly controlled to feed the growing population. The prevailing disinfestation techniques are forced to meet regulatory standards and market demands. The resistance developed by insects, environmental concerns, and occupational hazards lead to the vanishing of many chemicals used in insect and pest management programs. Some of the major disinfestation techniques such as the use of chemical fumigants, ozone, irradiation, dielectric heating, extreme temperature treatments, and bio rational approaches are discussed, particularly on the storage of cereal grains and its products, as they contribute to a significant proportion of food consumed worldwide. Newer techniques such as nonthermal plasma and metabolic stress disinfestation and decontamination for stored pest control are developed and evaluated in different parts of the world. The knowledge about the mode of action of these disinfestation techniques is important to avoid the cross-resistance and multiple resistance developed by insects with frequently used techniques. Various alternatives to conventional fumigants are discussed in this review as there is a growing demand for toxic-free, environment-friendly, and, at the same time, efficient techniques.

“…The application of low temperatures for control of stored-product insects has been extensively evaluated over the past three decades for many species of the orders Coleoptera, Lepidoptera and Psocoptera [1][2][3][4][5][6][7][8]. These studies show that stored-product insects vary remarkably in their susceptibility to low temperatures.…”

“…The majority of existing studies focus on the effect of temperatures below 0 • C. This is partially due to the fact that many major stored-product insect species can survive for several days, or even weeks, when exposed to 0 • C [1,4,7,9]. Exposure to temperatures lower than 0 • C may shorten the time required for mortality, but these lower temperatures may require more energy and thus may not be economically feasible in some instances.…”

“…Acclimation is considered to be a key element in cold tolerance of insects but has not been examined in detail in the case of stored-product insects, despite the fact that these insects are good candidates for the exploitation of "real world" cold treatments. A recent review by Andreadis and Athanassiou [4] underlines the lack of paradigms of cold tolerance of stored-product insects as compared with field crop pests. In addition, most of the data available for stored-product insects'cold tolerance are largely focused on non-acclimated individuals [1,3,5,7,9].…”

“…Thus, acclimation may not necessarily lead to cold hardiness but may instead accelerate death. In this context, some stored-product insect species may be opportunistic in terms of cold tolerance [4,8].…”

Insect survival after exposure to 0 °C for 7 days was examined in laboratory bioassays for control of adults of six major stored-product beetle species, Oryzaephilus surinamensis (L.), the sawtoothed grain beetle, Cryptolestes ferrugineus, (Stephens), the rusty grain beetle, Dermestes maculatus DeGeer, the hide beetle, Sitophilus oryzae (L.), the rice weevil, Tribolium castaneum (Herbst), the red flour beetle, and T. confusum Jacquelin DuVal, the confused flour beetle In this test there were four different acclimation treatments, insects that had been subjected to a pre-acclimation period to 0 °C, a post-acclimation period, both a pre and post-acclimation period, and adults that were not acclimated. Insect survival for all species except S. oryzae was not affected by the exposure to 0 °C, regardless of the acclimation scenario. In contrast, exposure to 0 °C drastically reduced survival of S. oryzae. Moreover, adults that were exposed to the post-acclimation only and un-acclimated adults had lower survival rates than those that had either exposure to pre-acclimation, or to both pre- and post-acclimation. Results of this experiment show that acclimation played a limited role in adult survival of five of the six tested species, and that exposure of adults to 0 °C for 7 d had no effect in survival of these species as well.

The red imported fire ant (RIFA), Solenopsis invicta Buren is native to South America and known as a global problematic invasive species. At low temperatures, several investigations have demonstrated an increase in glycerol as a primary rapid cold hardening (RCH) component and an increase in the supercooling point. Two genes, glycerol-3-phosphate dehydrogenase (GPDH) and glycerol kinase (GK), have been identified as being involved in the glycerol production process. In this study, one GPDH and two GK sequences were extracted from RIFA transcriptome analysis (Si-GPDH, Si-GK1, and Si-GK2). All three genes were expressed in different body parts and different tissues of S. invicta that Si-GK2 showed a higher expression level than the others. According to gene expression levels by qRT-PCR analysis, the highest expression levels of three genes were observed in fat body tissues. After 1 h of exposure to low temperatures (5°C or lower), the mRNA levels of these genes significantly increased, according to expression analyses. RNA interference (RNAi) of Si-GPDH or Si-GK1 and Si-GK2 exhibited a significant downregulation at the mRNA level. The mortality rate of treated RIFA by double-stranded RNA (dsRNA) specific to GPDH and GK2 significantly increased at low temperatures. This study indicates that GPDH and GK2 as glycerol biosynthesis genes in RIFA have a high expression
