Abstract The jumping worm Amynthas tokioensis is invasive in North America, and it has been expanding its range northward recent years. Because low temperatures typically restrict the geographic distribution of organisms, our goal was to characterize cold tolerance physiology adult worms from a site New Brunswick, Canada (c. 45°N), with intent better understanding their limits. Most experiments supported conclusion that these are chill-susceptible: they die during or after exposure relatively mild temperatures. When gradually cooled, lost neuromuscular coordination at approximately 0 °C froze mean temperature −4.5 °C. They did not survive freezing showed poor survival following 1 h exposures subzero At higher (5 °C), could short (up 6 h) but long (e.g., 48 chilling durations. We attempted induce improved via five-week gradual acclimation fall-like temperatures, fall-acclimated this acclimation. Acclimation also accumulation glucose, typical cryoprotectant earthworms. suggest A. can likely persist wherever growing season sufficiently warm enough for adults mature, reproduce, lay cocoons prior associated early fall. Future work examining overwintering will be important fully northern limits worms.

Abstract Heat shock proteins (HSPs) are well known to prevent and repair protein damage caused by various abiotic stressors, but their role in low temperature freezing stress is not well-characterized compared other thermal challenges. Ice formation around cells hypothesized cause damage, yet many species of insects can survive freezing, suggesting HSPs may be an important mechanism freeze tolerance. Here, we studied HSP70 a freeze-tolerant cricket Gryllus veletis better understand the this phenomenon. We measured expression one heat-inducible isoform at mRNA level (using RT-qPCR), as relative abundance total semi-quantitative Western blotting), five tissues from crickets exposed survivable heat treatment (2 h 40°C), 6-week fall-like acclimation that induces tolerance, (1.5 -8°C). While was upregulated or all (fat body, Malphigian tubules, midgut, femur muscle, nervous system ganglia), no tissue exhibited upregulation within 2 – 24 following stress. During mild temperatures, only saw moderate RNA fat body tissue. Although for responding wide range our work suggests chaperone less critical preparation for, response to, Highlights 70 (HSP70) contribute substantially tolerance spring field Acclimation prior correlated with slight after insect Further needed determine whether causes Graphical abstract
