Abstract

The drought tolerance of engorged I. persulcatus larvae was compared between the diapausing and non-diapausing groups. The survival rate abruptly decreased at74% RH and25°C in both engorged diapausing and engorged non-diapausing larvae. The mean longevity of the engorged diapausing larvae was significantly shorter than that of the engorged non-diapausing larvae when kept at74% RH and 25°C. The survival rate gradually decreased at 74% RH and 4°C in both larvae. There was not a significant difference in the mean longevity between the engorged diapausing and non-diapausing larvae when kept at 74% RH and4°C. These results suggest that engorged I. persulcatus larvae do not enhance the drought tolerance by the diapause.
