ab12 basiconic sensilla in the antenna show a higher citronellal-evoked action potential frequency in mutant flies compared to in wild type.
Mutant flies show significantly reduced avoidance of citronellal in a direct airborne repellent test (DART) assay.
ab11a olfactory receptor neurons (ORNs) in the antenna show a higher citronellal-evoked action potential frequency in mutant flies compared to in wild type.
