“…Glycerol is the major cryoprotectant in many arthropods, and the rapid loss of polyols associated with cold tolerance during deacclimation as demonstrated here has been reported in other species, including forest pests like the pine caterpillar Dendrolimus tabulaeformis (Zeng et al 2008). The majority of A. planipennis prepupae kept at 10 and 15°C showed visible signs of development at the end of the experiment (loss of prepupal j-shape, stout appearance, J.C. Crosthwaite & S. Sobek, unpublished observations).…”

“…While changes in SCP can be very rapid in some animals (e.g. Hawes et al 2007;Zeng et al 2008), SCPs are robust to external changes in others (e.g. Andreadis et al 2005;Bale et al 2000;Lombardero et al 2000).…”

“…Phenotypic plasticity is thought to facilitate the success of organisms in new environments (Ghalambor et al 2007), but may also have adverse effects, for example leading to a loss of cold hardiness due to deacclimation if conditions become too warm (Fields et al 1998;Zeng et al 2008). In particular, if plasticity is not reversible, deacclimation would alter the ability of the insect to survive subsequent cold exposures, but the reversibility of phenotypic plasticity has rarely been explored experimentally at short time scales (Angilletta 2009).…”

Could phenotypic plasticity limit an invasive species? Incomplete reversibility of mid-winter deacclimation in emerald ash borer

et al. 2011

The emerald ash borer (Agrilus planipennis, Coleoptera: Buprestidae) is a wood-boring invasive pest devastating North American ash (Fraxinus spp.). A. planipennis overwinters primarily as a freezeavoiding prepupa within the outer xylem or inner bark of the host tree. The range of this species is expanding outward from its presumed introduction point in southwestern Michigan. We hypothesized that loss of cold tolerance in response to mid-winter warm spells could limit survival and northern distribution of A. planipennis. We determined whether winter-acclimatised A. planipennis prepupae reduced their cold tolerance in response to mid-winter warm periods, and whether this plasticity was reversible with subsequent cold exposure. Prepupae subjected to mid-winter warm spells of 10 and 15°C had increased supercooling points (SCPs) and thus reduced cold tolerance. This increase in SCP was accompanied by a rapid loss of haemolymph cryoprotectants and the loss of cold tolerance was not reversed when the prepupae were returned to -10°C. Exposure to temperatures fluctuating from 0 to 4°C did not reduce cold hardiness. Only extreme warming events for several days followed by extreme cold snaps may have lethal effects on overwintering A. planipennis populations. Thus, distribution in North America is likely to be limited by the presence of host trees rather than climatic factors, but we conclude that range extensions of invasive species could be halted if local climatic extremes induce unidirectional plastic responses.

“…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. 2008).…”

Exploring the plastic response to cold acclimation through metabolomics

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.

“…But there are no studies on the photoperiodic response of individuals from univoltine populations and whether they have a "longer" CDL is unknown. Moreover, previous studies on this moth were mainly on photoperiodic induction (Li & Gia, 1991;Li et al, 1994Li et al, , 1995Huang et al, 2005) or coldhardiness of larvae in diapause (Han et al, , 2008Zeng et al, 2008), but not on the photoperiodic regulation of diapause development, including diapause intensity and post-diapause development. The present study analyzes the photoperiodic response of individuals from a univoltine population of D. punctatus in terms of the above diapause parameters.…”

Abstract. Larvae of Dendrolimus punctatus overwinter in diapause. In the Yangtze River Region, this species is multivoltine at altitudes below 400 m and univoltine above 700 m a.s.l. The photoperiodic response of the univoltine population, investigated at five day lengths (11.5, 12.5, 13.5, 14.5 and 15.5 h) at 27 + 1°C, indicates that D. punctatus is a long-day species. Diapause was induced in 95-100% of the individuals by three short photophases (11.5-13.5 h), while diapause incidence decreased steeply with increase in day length down to 10% at 15.5 h. The critical daylength (CDL = day length resulting in a 50% incidence of diapause) is 14.6 h. When induced by critical or longer photophases (14.5 and 15.5 h), diapause terminated spontaneously, without any change in photoperiod or temperature. Diapause induced at shorter photophases was more intense and not terminated without activation by diapause averting conditions. Larvae in diapause lived for up to 190 d when kept under a 11.5 h photophase during which they remained sensitive to the photoperiodic signal. In transfer experiments, diapause was terminated after an increase in photoperiod, even if it was within the range of diapause inducing photoperiods: from 11.5 h to 13.5 h. This study revealed that the univoltine hill dwelling population of D. punctatus undergoes a facultative diapause. Although potentially multivoltine they are univoltine because of the low temperatures at that altitude.
