Ilp21 homozygous mutant third instar larvae present similar numbers of abdominal adult muscle precursor cells, as compared to controls.
Female Ilp21 flies show a significantly reduced re-mating rate 24 hours after mating to wild-type flies, compared to control flies.
Ilp21 mutants are 100% viable; show a delay in egg-to-adult development time; show a slight reduction in adult body weight; have an increased median lifespan (at all food concentrations, excepting starvation conditions); have significantly reduced lifetime fecundity; show normal paraquat resistance, starvation resistance, and lipid and glycogen storage; and increased whole body trehalose levels.
