Physiology of insect diapause
Webb1. The physiological control of pupal diapause has been studied on a total of approximately 1200 pupae of the giant silkworms, Platysamia cecropia, Telca polyphemus, Samia walkeri, and Callosamia promethea. 2. The dormancy of diapausing pupae can be terminated readily by grafting them to activated (previously chilled) pupae.

WebbDiapause allows insects to overcome harsh seasons and exploit fluctuating resources. Diapause phenotype includes photoperiodism, hormonal regulation, cessation of development, altered gene expression, cell cycle arrest, accumulation of energy reserves, metabolic suppression, and bolstered environmental stress tolerance. Webb1 aug. 2007 · Insects in diapause characteristically feed very little or not at all, thus they are largely or totally dependent on energy reserves sequestered prior to the entry into diapause. Fats are the dominant reserve used during this period, but non-fat reserves are also important for some species, especially during certain phases of diapause.

Experiments with the bean beetle Riptortus pedestris ( 91 ) and the mosquito Culex pipiens ( 130 ) provide some of the strongest evidence that the circadian …
