Behavioural response of Trissolcus brochymenae with rewarded experience.
Mean (±SE) residence time of Trissolcus brochymenae females allowed to oviposit on a host egg mass in the presence of either host female or male traces and then tested according to different conditions: F_o_F = oviposition on female traces and tested on female traces, N = 32; M_o_M = oviposition on male traces and tested on male traces, N = 31; F_o_B = oviposition on female traces and tested on uncontaminated cabbage leaf disks, N = 35; M_o_B = oviposition on male traces and tested on uncontaminated cabbage leaf disks, N = 34. Different letters above bars indicate significantly different means (GLM, *P < 0.05).
