Regardless of which insect antennae in the virtual environment detected the odor, we provided the odor stimulus to both antennae of the actual silkmoth. This meant that the silkmoth lost bilateral information of odor. Vision and wind were presented in the same way as in cond. i. (A, B, and C) represent the results of the search success rate, search time, and search performance, respectively. (D and E) represent the trajectories with and without bilateral information, respectively. The blue and black lines of the trajectories represent success and failure, respectively. When the bilateral information of the odor is lost, the search success rate drops significantly because the momentary direction information is lost. This means that the left and right odor information is important in the odor-source search, and that our odor stimulator correctly provides the odor information into the left and right antennae.
