      Expression of Ir21aGD773 under the control of Scer\GAL4Gr64f.9.7 in adults does not obviously reduce proboscis extension rates in response to fatty acids, or to sucrose, compared to controls.

      (Ahn et al., 2017)

      Expression of Ir21aGD773 under the control of Scer\GAL4elav.PU (in combination with a Dicer-2 transgene to enhance RNAi efficiency) does not lead to a significant change in female feeding preference index for 1% yeast extract versus 5mM sucrose solution, as compared to controls.

      (Ganguly et al., 2017)

      Adults expressing Ir21aGD773 under the control of Scer\GAL4elav.PLu (in the presence of Dcr-2Scer\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.

      (Neely et al., 2010)

      Expression under the control of Scer\GAL4pnr-MD237 may result in semi-lethality, depending on the insertion line used.

      Expression under the control of Scer\GAL4pnr-MD237 results in a colour difference between the central Scer\GAL4pnr-MD237 expression domain of the notum and the surrounding lateral region in 0% or 10-20% of the Scer\GAL4pnr-MD237 expression domain, depending on the insertion line used.
