[Resistance to starvation in insects: importance of the amount of lipid reserves in adult Drosophila melanogaster].
At 25 degrees C, mean survival duration of adults starved after emergence varied from 58 to 112 hours, according to genotype and larval growth conditions. This duration was highly correlated with the amount of lipids. The great variability in the amount of lipids (from 15 to 35% of initial dry weight) seems to have an adaptative significance for adult survival in natural conditions.
