Life span is the main life history trait to describe aging. Life span is affected by many factors that can reduce the viability. In general, life span varies with genotype and environmental factors related.In this study, the effect of dietary restriction, which is strong environmental variable for life span was investigated. In particular, life spans of the different starvation resistance lines which were food restricted at larval and adult stages were analysed. We study the effect of dietary restriction on larval and adult stage of life span with four isofemale line selected by starvation resistance.The findings indicate that dietary restrictions at adult stage have higher impact on life span compared larval dietary restriction. However, restricted feeding in both larval and adult stages has a cumulative effect on life span. In general, dietary restriction which was created by reducing yeast levels from the optimum amount (100 g l) reduces the mean life span.
