Frequency distribution of adult eclosion in diapausing pupae of <i>H. cunea</i>.

<p>The diapausing pupae were transferred to LD 15∶9 at 25°C after exposure to 5°C and DD for different numbers of days. The hatched bar indicates the period of cold exposure. Values followed by different letters are significantly different by Tukey’s multiple comparisons (<i>P</i><0.05). Values in parentheses are survival rates after diapause and numbers of adults emerged from diapausing pupae.
