Adult flies are hypoactive. Adults die 3-7 days after eclosion at 29oC. Mosaic analysis reveals paired lethal foci that appear to map in the vicinity of the subesophageal ganglion.
Fate mapping suggests presence of bilateral domineering foci located in or near the subesophageal ganglion responsible for both hypoactivity and lethality at 29oC (Homyk, Sinclair, Wong and Grigliatti, 1986). not temperature-sensitive during development hypoactive adults die 3-7 days after eclosion at 29oC.
