“…In the present study, RCH was induced in diapausing C. suppressalis larvae after a short exposure (2–4 h) at 5 °C. In many other insects, RCH has been induced at temperatures ranging 0–5 °C [ 7 , 8 , 21 , 22 , 23 , 24 , 25 ], or even at 10 °C for the predatory mite Euseius (Amblyseius) finlandicus [ 21 ] and the fruit fly Bactrocera oleae [ 22 ] and −2 °C for a Karoo beetle Afrinus sp [ 26 ]. In non-diapausing C. suppressalis mature larvae, a previous report showed that RCH could be induced at 0 °C for 4 h and to a lesser extent, at 5 °C for 4 h [ 10 ].…”

The striped stem borer, Chilo suppressalis (Walker), overwinters as a diapausing larva. The diapausing larvae were tested for a rapid cold hardening (RCH) response and its role in the insect’s survival of sub-zero temperatures. When laboratory-reared diapausing larvae were transferred directly from the rearing temperature of 25 °C to −14 °C and maintained there for 2 h, 21% survived. Acclimation of diapausing larvae for 4 h at 5 °C before their exposure for 2 h to −14 °C increased survival to approximately 41%, indicating an RCH response. Durability of RCH effects on low temperature survival was less than 1 h. Although transient in the test, the increased survival acquired through rapid cold hardening may play a role in preparing the diapausing larvae for abrupt temperature drops in the field that would otherwise be lethal.

“…The RCH-related physiological adjustments are often small [ 12 ]. RCH only elicited few changes in the abundance of detectable proteins in D. melanogaster [ 13 ]; and in Locusta migratoria , heat shock proteins were generally down-regulated [ 24 ]. According to Teets, N.M. and Denlinger, D.L.…”

“…Therefore it remains reasonable to consider a diverse array of mechanisms underlying physiological responses to gas stress on low temperature survival (reviewed in Boardman et al, 2011). Exposure to anoxia affects low temperature responses in unpredictable ways (Coulson and Bale, 1991;Yocum and Denlinger, 1994;Nilson et al, 2006;Cui et al, 2014) possibly through a generalised stress response, alterations to metabolic rate or the additional effects of desiccation imposed by anoxia (e.g. Levis et al, 2012).…”

“…In insects without diapause, RCH is especially important for overcoming lethal cold shock by rapidly increasing cold tolerance 20 . RCH has been induced in a variety of insects at temperatures ranging from 0 to 5 °C 30 , 43 – 47 . Glycerol production is divided into two distinct pathways, depending on the insect.…”

The fall armyworm (FAW), Spodoptera frugiperda, is native to the tropical and subtropical areas of the American continent and is one of the world's most destructive insect pests and invaded Africa and spread to most of Asia in two years. Glycerol is generally used as a cryoprotectant for overwintering insects in cold areas. In many studies, the increase in glycerol as a main rapid cold hardening (RCH) factor and enhancing the supercooling point was revealed at low temperatures. There are two genes, including glycerol-3-phosphate dehydrogenase (GPDH) and glycerol kinase (GK), that were identified as being associated with the glycerol synthesis pathway. In this study, one GPDH and two GK sequences (GK1 and GK2) were extracted from FAW transcriptome analysis. RNA interference (RNAi) specific to GPDH or GK1 and GK2 exhibited a significant down-regulation at the mRNA level as well as a reduction in survival rate when the RNAi-treated of FAW larvae post a RCH treatment. Following a cold period, an increase in glycerol accumulation was detected utilizing high-pressure liquid chromatography and colorimetric analysis of glycerol quantity in RCH treated hemolymph of FAW larvae. This research suggests that GPDH and GK isozymes are linked to the production of a high quantity of glycerol as an RCH factor, and glycerol as main cryoprotectant plays an important role in survival throughout the cold period in this quarantine pest studied.
