Evidence of prolonged diapause in prepupae of the variable oakleaf caterpillar heterocampa manteo


, : Evidence of prolonged diapause in prepupae of the variable oakleaf caterpillar heterocampa manteo. Environmental Entomology 7(2): 186-188

In Michigan [USA], 27-70% of the prepupae of H. manteo (Dbldy) remained in diapause longer than 1 yr and up to 31% diapaused for 2 yr. Diapause was facultative, but the factors of development were not determined. Prolonged prepupal diapause of H. manteo is believed to contribute to cyclical outbreaks and provides a means of avoiding population collapse due to starvation and parasitism. Application of insecticides over extensive areas could, by depressing univoltine parasites of H. manteo, reduce the parasitism rates of those H. manteo in prolonged diapause and emerging the year subsequent to insecticide applications.
