โœฆ Synopsis


Abstract

Acclimation of Meracantha contracta larvae collected in late summer to low temperatures, short photoperiods or low relative humidities induces production of a macromolecular antifreeze which functions to depress the freezing and supercooling points of the larvae. Overwintering larvae must be exposed to a combination of high temperature and long photoperiod before the antifreeze is lost.
