Genetic dissection of stress-induced reproductive arrest in Drosophila melanogaster females
Fig 5
A model illustrating the molecular events likely underlying the regulation of reproductive dormancy in female D. melanogaster.
External (light and temperature) and internal (nutritional) information converge onto brain IPCs, which in turn stimulate or suppress synthesis of JH in corpora allata. JH acts on the ovary and other tissues to prevent reproductive dormancy and other biological changes associated with dormancy.
