      Expression of Ir76bGD2741 under the control of Scer\GAL4elav.PU (in combination with a Dicer-2 transgene to enhance RNAi efficiency) leads to a significant reduction in female feeding preference index for 1% yeast extract versus 5mM sucrose solution, as compared to controls.

      In a feeding preference assay for amino-acid-depleted yeast extract supplemented with serine, threonine and alanine, females expressing Ir76bGD2741 under the control of Scer\GAL4elav.PU (in combination with a Dicer-2 transgene to enhance RNAi efficiency) exhibit a drastically decreased preference index, as compared to controls.
