The expression of Ype^GD8633 under the control of Scer\GAL4^pnr-MD237 results in darkened small patches along the midline of the scutellum and posterior scutum, ectopic scutellar bristles and missing ocellar/postvertical bristles.

The expression of Ype^GD8633 under the control of Scer\GAL4^Act5C.PI results in developmental delay, with individuals reaching adulthood roughly 3-4days later than control, having difficulty eclosing (breaking the operculum but then becoming stuck and dying as they crawled out of the pupal case); adults exhibit darkened broad but discrete patches of cuticle across the body, wings that are held out laterally and curved downward, and ectopic scutellar bristles.

Adults expressing Ype^GD8633 under the control of Scer\GAL4^nub-AC-62 exhibit wings that are held out and curved downward.

Adults expressing Ype^GD8633 under the control of Scer\GAL4^r4 leads to delayed development to adulthood by 2-3 days.

Adults expressing Yippee^GD17271 under the control of Scer\GAL4^elav.PLu (in the presence of Dcr-2^Scer\UAS.cDa to increase the efficiency of RNAi) do not show a significant defect in avoidance of noxious temperature (46[o]C) compared to control flies.

Expression under the control of Scer\GAL4^pnr-MD237 results in a colour difference between the central Scer\GAL4^pnr-MD237 expression domain of the notum and the surrounding lateral region in 0% or 40-50% of the Scer\GAL4^pnr-MD237 expression domain, depending on the insertion line used.
