UAS regulatory sequences drive expression of a short-hairpin Bili RNA.
embryonic/first instar larval cuticle, with Scer\GAL4prd.RG1
Expression of BilidsRNA.Scer\UAS.sh under the control of the P{GAL4-prd.F} driver results in the secretion of mostly naked cuticle with very few cells secreting cuticle with denticles.
