Prior to the demonstration, several locusts will be trained on a target odor (eg. Hexanol), according to the protocol described in the appended paper. The demonstration setup (Fig 1) consists of a trained locust (free or restrained) enclosed in a transparent enclosure, an odor delivery system and a palp tracking system. The odor delivery system contains an air pump with two outputs. One of the outputs (main line) goes directly to the locust through a filter. This tube helps in maintaining a constant flow rate over the duration of the experiment. The other output passes through an odor bottle and joins the main tube. The flow through this tube is controlled by a solenoid valve that is operated by the demonstrator. The odor bottles will contain either hexanol (target odor) or benzaldehyde (control). Entire setup occupies less than 3 feet by 2 feet and requires one power outlet for driving the pump.
