InterventionCaloric restriction
Alternate Name
OrganismCeratitis capitata
Aging PhenotypeNo effect on life-span
Allele TypeN/A
DescriptionDietary restriction over a range of 60-100% ad libitum (AL) caloric consumption had no effect on life-span (Carey et al., 2002). When caloric consumption was restricted to less than 50% of AL consumption, mortality increased dramatically and mean and maximum life-span were decreased.
Gene FunctionN/A
Other PhenotypesAt most dietary levels, C. capitata males have a life-span that is longer than females (Carey et al., 2002). Females reproduce across all diet levels (30-100% AL) although fecundity drops sharply at lower caloric consumption.
