Orientation of parasitoid Cotesia vestalis in Y-tube olfactometer assays. The selection of the individually tested parasitoids (% of parasitoids making a selection) towards either of the odour sources in a two-arm olfactometer is shown. Intact, host-damaged and R. tomentosum (RT)-exposed refer to treatments of B. oleracea plants. Host-damaged plants experienced 48 h of Plutella xylostella L. larval feeding and RT-exposed plants neighboured a potted R. tomentosum plant for 48 h before testing at the temperature shown. The total number of parasitoids tested (n) and number of individuals making a selection towards the odour sources are also reported. Statistically significant differences in the selections are indicated by asterisks (*P < 0.05).
