Effects of the translation-inhibitor ANI on the response of T. evanescens wasps to odors of adults of the Large Cabbage White butterfly P. brassicae at 1 h and 24 h after a rewarding H experience (H+O). Mean residence time (± SEM.) in 2 odor fields in a 2-chamber olfactometer; n = 40 wasps tested per experiment; ANI, wasps were fed sucrose plus ANI before experience; C, control wasps were fed only sucrose before experience. Asterisks indicate significant differences within a choice test (Wilcoxon matched pairs signed-ranks test); ***, P < 0.001; ns, not significant.
