A Maternal Effect That Eliminates Pupal Diapause in Progeny of the Flesh
Flesh flies that have experienced pupal diapause produce progeny that will not enter diapause even when reared in a strongly diapause-inducing environment. The effect is determined, not by diapause itself, but by the short days previously received by the larvae during the programming of pupal diapause. Reciprocal cross matings indicate that the effect is transmitted solely by the female parent....
متن کاملMendelian inheritance of pupal diapause in the flesh fly, Sarcophaga bullata.
Pupal diapause (dormancy) in the flesh fly, Sarcophaga bullata, is induced by short-day photoperiods and low temperature. In this study, the inheritance mode of diapause was investigated by crossing a nondiapausing (nd) strain of S. bullata with 2 diapausing strains having different diapause capacities. The results consistently indicated that diapause incidence is inherited in a simple Mendelia...
متن کاملProteomic approach to understanding the maternal effect in the flesh fly, Sarcophaga bullata (Diptera: Sarcophagidae)
Progeny of the flesh fly Sarcophaga bullata exposed to short day length show a maternal effect that prevents the expression of pupal diapause. Although ecological aspects of this effect are well studied, not enough is known about the molecular mechanisms underlying this maternal effect. In this study, two-dimensional electrophoresis was performed to detect differences of the abundance of certai...
متن کاملThe Cytological Effect of Ecdysterone on the Midgut Cells of the Flesh-fly Sarcophaga Bullata
Larvae of the flesh-fly, Sarcophaga bullata, were injected with the synthetic moulting hormone ecdysterone or saline at the beginning of the third and final larval instar. One group was left untreated. The ecdysterone-injected larvae showed an increase in number of secondary lysosomes in the midgut epithelial cells similar to that observed at the onset of metamorphosis, an event which would nor...
متن کاملOleic acid is elevated in cell membranes during rapid cold-hardening and pupal diapause in the flesh fly, Sarcophaga crassipalpis.
The integrity of cellular membranes is critical to the survival of insects at low temperatures, thus an advantage is conferred to insects that can adjust their composition of membrane fatty acids (FAs). Such changes contribute to homeoviscous adaption, a process that allows cellular membranes to maintain a liquid-crystalline state at temperatures that are potentially low enough to cause the mem...
