Cold hardiness and some ecological observations of the European corn borer, Ostrinia nubilalis (Heubn.) in Manitoba
Cold-hardiness of diapausing corn borer larvae is correlated with the glycerol concentration. Larvae containing 5.7% glycerol are cold-hardy at -10, -22 and -35*C whereas those containing 5.0% glycerol are cold-hardy only at -10 and -22*C. The larvae containing 2.1% glycerol are not cold-hardy....
