Orco increases antennal electrophysiological activity in C. maculatus.
“RNA interference (RNAi)-mediated knockdown of Orco significantly reduced mating-related behavioral responsiveness and antennal electrophysiological activity in both populations, confirming its essential role in olfactory function.”

Orco is associated with odor-guided aggregation dynamics in C. maculatus.
“Group-level behavioral analyses revealed a significant effect of Orco knockdown on odor-guided aggregation dynamics over time, while no significant effect of population was detected.”
