Overexpression of Cyp18a1Scer\UAS.cGa driven by Scer\GAL4Cyp6g1.HR in the larval midgut, Malpighian tubules and fat body results primarily in third instar larval lethality, with a number of individuals surviving until early pupal stages. Melanotic masses can be seen in many larvae, often associated with the midgut and cuticle.
Ubiquitous overexpression of Cyp18a1null644 driven by Scer\GAL4tub.PU results in late embryonic lethality. This embryonic lethality can be rescued to first instar larval stage by incubating embryos in 20-hydroxyecdysone (20E).
Overexpression of Cyp18a1Scer\UAS.cGa driven by Scer\GAL4phm.PG in the prothoracic cells of the ring gland results in late embryonic lethality. This embryonic lethality can be rescued to first instar larval stage by incubating embryos in 20-hydroxyecdysone (20E).
