Comparison of antennal responses to the main sex pheromone components in wild type (WT) and Orco^−/− Helicoverpa armigera adults, assessed using single sensillum recordings (SSRs). A Representative response profiles of WT-type A, WT-type B, WT-type C, and Orco^−/−. B Spike frequencies represented with histograms of WT-type A, WT-type B, WT-type C, and Orco^−/−. The number of spikes was counted from the first 500 ms of the response. Paraffin oil was used as a control (multiple t-test: *, P < 0.05; **, P < 0.01; ***, P < 0.001). Error bars, mean ± SD
