Summary

The New Zealand alpine cockroach survives temperatures up to 5 deg C below its supercooling point of -5.4 deg C in summer-acclimated samples. The distribution of ice nucleating agents within the cockroach was investigated by measuring the supercooling point and ice nucleator activity of component parts of the body. Both the haemolymph and gut contain high numbers of nucleators active at -4 deg C.
