Mutant larvae show a marked increase in the number of mitotically active cells in the brain compared to controls.
The median lifespan for prosV24 animals (the age after egg laying at which 50% of homozygotes have died) is 5.48 days at 25oC.
Homozygous third instar larvae show reduced locomotor activity compared to controls.
Homozygous second instar larvae are indifferent to 0.1M sucrose in a taste response assay, in contrast to wild-type larvae which are significantly attracted by sucrose. They are repulsed by 0.3M NaCl (as are wild-type larvae).
The courtship index of heterozygous males towards decapitated Canton-S males is not significantly different from that of wild-type males towards decapitated Canton-S males. Homozygotes die mostly during pupal development.
