Abstract:

Rearing tests show that red-banded leaf roller (Argyrotaenia Velutinana (Walker)) larvae predisposed to diapause (pupal stage) by short photoperiods have an arrested development period in the last instar. At 80° F. in the laboratory this period ranged from10 to 40 days longer than normal. The same phenomenon was observed in nature and lasted for 33 or more days. The possible significance of this arrested development is discussed.
