Cold tolerance of first-instar nymphs of the Australian plague locust, Chortoicetes terminifera

Woodman, James

Description

The cold tolerance of first-instar nymphs of the Australian plague locust, Chortoicetes terminifera, was examined using measures of total body water content, supercooling point and mortality for a range of sub-zero temperature exposure regimes. The supercooling points for starved and fed nymphs were -13.1 ± 0.9 and -12.6 ± 1.6 °C, and freezing caused complete mortality. Above these temperatures, nymphs were cold tolerant to different degrees based on whether they were starved or given access to...[Show more]
