Flies expressing Or42bScer\UAS.T:Hsap\MYC under the control of Scer\GAL4Or22a.8197 in a Df(2L)dp-79b/Dp(2;2)dppd21 background (called Δhalo) show a large increase in electrophysiological response to either 2-ethylpyrazine or 2-methylpyrazine.
Low concentrations of ethyl acetate elicit a strong response in flies expressing Or42bScer\UAS.T:Hsap\MYC under the control of Scer\GAL4Or22a.8197 in a Df(2L)dp-79b/Dp(2;2)dppd21.
