Relationship between locomotor activity, oxidative stress and aging in fire bug \kur{Pyrrhocoris apterus}
 BUŘIČOVÁ, Marcela
The hypothesis that experimental manipulations increasing life span correlate to reduced physical activity and reduced molecular oxidative damage was tested. We used three longevity phenotypes of males and females of Pyrrhocoris apterus, diapause insects, reproductive insects and insect with ablation of the corpus allatum, an endocrine gland producing juvenile hormone. Protein carbonyl content in thoracic muscles was used as an index of molecular oxidative modification.

The effect of food restriction on longevity in an insect model
 BUŘIČOVÁ, Marcela
It is known that the restricted food intake in many species extends lifespan by slowing and/or delaying the aging processes. The underlying biological mechanisms responsible for the lifespan extension are still not known, althought several hypotheses have been proposed. Cost of reproduction, where the lifespan and fecundity are negatively correlated, is of widespread occurrence. In females of the linden bug Pyrrhocoris apterus no evidence for a trade-off between lifespan and fecundity were observed. Restriction of food intake reduces egg production but has no effect on lifespan.
