Functional tests of candidate genes and their effects on (a), (b) odor-guided behavioral responses to 4-ethylguaiacol and (c), (d) food consumption. For each trait, the effects of RNAi-mediated knockdown of 16 candidate genes in either projection neurons of the antennal lobe (GH146-GAL4) or in Or71a-expressing neurons (Or71a-GAL4) were examined in both females (gray bars) and males (white bars). Values are deviations from the control. Error bars indicate SE. *: P < 0.05. N = 10
