Difference in nutrient accumulation patterns between diapause‐destined and non‐diapause‐destined larvae of Hyphantria cunea

Abstract

Dormancy is a physiological state in which development and metabolism are temporarily suppressed, and it permits invertebrates to synchronize the completion of their life cycle to the seasonal fluctuations of their resources (Danks, 1987;Koštál & Denlinger, 2011). Diapause is a specific type of insect dormancy that may last for many months (Koštál, 2006;Hahn & Denlinger, 2011). Diapausing insects are generally inactive and do not feed. Therefore, nutrient accumulation prior to diapause not only allows insects to survive low winter temperatures but also provides the energy needed for standard metabolism during the winter and portions of the autumn or
