Abstract: The oriental fruit moth, Grapholitha molesta (Busck), is an important pest of peach and other fruit crops in north China. Previous research found that this moth did the most serious harm to peach crops in Feicheng, Tai’an. In this paper, the supercooling ability and biochemical substances in diapausing and nondiapausing larvae of G. molesta were determined. The results show that, at a temperature of 26℃, the supercooling point (SCP) and freezing point (FP) of diapausing larvae were lower than those of nondiapausing larvae, but that this difference was not significant. The freewater, glycogen and protein content of diapausing larvae were significantly lower than in nondiapausing larvae, however totalfat, glycerin and trehalose in diapausing larvae were significantly higher than in nondiapausing larvae. These results indicate that diapausing larvae may adjust their biochemical processes to enhance resistance to colder temperatures.
