    Effect of rapid cold-hardening (RCH) on the cold tolerance of pharate adult flesh flies. Cold-shocked flies were directly exposed to the indicated test temperature for 2 h, while flies in the RCH groups were exposed to 0°C for 2 h prior to being transferred to the test temperature. Flies that successfully eclosed as adults were considered alive. Chen C-P, Denlinger DL, Lee RE () Cold-shock injury and rapid cold hardening in the flesh flySarcophaga crassipalpis.

Rapid cold hardening (RCH) is an adaptation enabling insects to quickly respond to low temperature, but little is known about the molecular events that trigger this response. In this study of the flesh fly Sarcophaga crassipalpis, we explore a possible role for mitogen-activated protein kinases (MAPKs) in the low temperature signaling that elicits RCH. We report that p38 MAPK .

Entomol. 21, doi: /jtbxCited by: 1. Direct exposure to C, in the absence of tissue freezing, causes high mortality in Sarcophaga crassipalpis: this result suggests that injury is due to cold shock.

However, brief acclimation at 0 C enables larvae, pupae, and pharate adults of Sarcophaga crassipalpis to survive C. Chilling for as short a period as 10 min enabled 50% of the flies to survive a 2-h exposure to C Cited by:   A rapid cold-hardening process in insects.

Lee RE Jr, Chen CP, Denlinger DL. rapid cold-hardening response was observed in nonoverwintering stages that confers protection against injury due to cold shock at temperatures above the supercooling point. This response was observed in nondiapausing larvae and pharate adults of the flesh fly Cited by: Abstract Brief exposure to low (0 o C) or high (40 o C) temperature elicits a protective response that prevents injury when the flesh fly, Sarcophaga crassipalpis Macquart, is subjected to more severe cold (‐10 o C) or heat (45 o C).

Both the low and high temperature responses were found in all developmental stages of the fly, but were most pronounced in the pupal and pharate adult.

and Denlinger, D. () A comparison of the protection generated by cold shock and heat shock in the flesh fly, Sarcophaga. For example, when non-diapausing individuals of flesh fly, Sarcophaga crassipalpis, in their pharate adult stage are directly exposed to −10 °C for 2 h, nearly all individuals succumb to death due to non-freezing chilling injury; yet, if flies are chilled at 0 °C for as little as 30 min prior to the same low-temperature exposure, rates of.

Traditionally studies of cold tolerance in insects have focused on seasonal adaptations related to overwintering that are observed after weeks or months of exposure to low temperature. In contrast, an extremely rapid cold-hardening response was observed in nonoverwintering stages that confers protection against injury due to cold shock at temperatures above the.

The capacity to undergo rapid the cold-hardening response (RCH) has been documented in diverse groups of insects and functions to protect against non-freezing cold injury and to preserve physiological performance in response to environmental cooling.

The RCH response is remarkable for the rapidity of its induction; however the mechanism by which insects perceive cold. Heat shock (45°C), cold shock (−10°C), and indirect chilling injury (a prolonged exposure to 2°C) did not interfere with the continuation of pharate adult development in the flesh fly, Sarcophaga crassipalpis, but such flies failed to eclose properly when the exposure was of sufficient all three forms of injury, development following the temperature.
