[Effect of selection on the criterion of resistance to starvation in adults of Ceratitis capitata Wied (Diptera, Trypetidae)].
The mecanisms of resistance to starvation of adult Ceratitis capitata are analysed. This study is based on comparison of two laboratory strains: one which was previously selected for "resistance to starvation" the other which has never been selected. Resistance to starvation appears to be determined, on the one hand by reserves in the insect and their hourly rate of utilisation on the other hand by the efficiency of the antidiuretic system. The selection, which increased adult resistance to starvation acted upon these three factors. It modified the strategy of energy utilisation by inducing a more economic energy budget.
