Figure 2

Attractiveness of Brassica rapa plants to parasitoids at different developmental stages. Percentage attractiveness of Cotesia glomerata females toward different treatments in 4-arm and 6-arm olfactometer settings. Treatments are: Blank empty odor source, Ctrl non-infested plant, Infested or Inf Pieris-infested plant, Veg vegetative plant, Flo flowering plant, PreFlo plant in the pre-flowering stage. Settings are: A 4-arm olfactometer with flowering plants; B 4-arm olfactometer with vegetative plants; C and D 6-arm olfactometers. Treatments followed by a different letter are significantly different (One-way ANOVA, α = 0.05, JMP 9).
