Whereas Scer\GAL4da.PU-mediated expression of FASN3dsRNA.WIZ.Scer\UAS (plus Dcr-2Scer\UAS.cDa) is lethal at the larval L2 stage, co-expression of Scer\GAL80svp.3kb which inhibits Scer\GAL4 in the oenocytes results in viable flies.
Flies expressing FASN3dsRNA.WIZ.Scer\UAS under the control of Scer\GAL4insc-Mz1407 are extremely sensitive to dessication, with significantly decreased survival time during dessication stress, as compared to controls. In mating choice assays, wild type flies do not exhibit a significant difference in preference for opposite sex flies expressing FASN3dsRNA.WIZ.Scer\UAS under the control of Scer\GAL4insc-Mz1407 versus controls.
Expression of CG17374dsRNA.WIZ.Scer\UAS under the control of Scer\GAL4sal.BO results in lethality at the L2/L3 larval transition.
Larvae expressing CG17374dsRNA.WIZ.Scer\UAS under the control of Scer\GAL4sal.BO and transferred to blue tinted food medium at the L2 or early L3 stage show blue staining of the spiracles that sometimes extends into the main tracheal trunks, indicating a water-tightness defect in the spiracles.
