We used a combination of metabolomics and manipulative experiments in vivo and ex vivo to examine the function of multiple cryoprotectants in the spring fieldcricket Gryllus veletis. Cold-acclimated G. veletis are freeze-tolerant and accumulate myo-inositol, proline and trehalose in their haemolymph and fat body. Our study is the first to experimentally demonstrate the importance of non-colligative cryoprotectant function for insect freeze toleranceboth in vivo and ex vivo, with implications for choosing new molecules for
cryopreservation.
