Oviposition preference experiment of wild type (WT) and Orco−/− Helicoverpa armigera females. A Number of eggs distributed in area of green pepper fruit discs and control. A multiple t-test was used to detect differences between treatments (*, P < 0.05; **, P < 0.01; ***, P < 0.001). B Oviposition preference index between the host plant (green pepper) and control. The formula (T − C)/(T + C) was used to calculate the preference index, where T is the number of eggs in the host plant area, and C is the number of eggs in the control area. A multiple t-test was used to detect differences between treatments (*, P < 0.05; **, P < 0.01; ***, P < 0.001). Error bars, mean ± SD
