[Delay and cessation of aging processes by manipulation of reproduction, food intake and development in insects].
Insects can serve as excellent models to show that the genetically determined life span of organisms as well as that of other traits is characterized by high phenotypic plasticity. Depending on different environmental conditions the life cycle strategy can therefore be highly variable. Thus developmental and aging processes are subjected to delaying or accelerating influences or can even be interrupted. Availability of protein to fulfill reproductive requirements, intermittent starvation, and the photoperiodic induction of reproductive diapause were taken as examples for the study of selected abiotic factors which influence the life history of the blowfly Phormia terraenovae and the beetle Gastroidea viridula.
