  abstract = {{W}e examined whether maize offers enemy-free space ({EFS}) to its pest {O}strinia nubilalis, and may thereby have contributed to its divergence from the sibling species, {O}strinia scapulalis, feeding mainly on mugwort, when introduced into {E}urope five centuries ago. {W}e collected {O}strinia larvae on maize (70 populations, 8425 individuals) and mugwort (10 populations, 1184 individuals) and recorded parasitism using both traditional (counting emerging parasitoids) and molecular methods (detection by specific polymerase chain reaction). {T}he main parasitoid was {M}acrocentrus cingulum ({B}raconidae). {O}n mugwort, parasitism was twice that on maize, and parasitoid-related mortality was 8 times higher. {T}his suggests that maize affords substantial {EFS} to {O}strinia feeding on it. {T}he lower {M}ortality:{I}nfestation ratio in maize suggests that {O}. nubilalis' immune response might be stronger than that of {O}. scapulalis. {I}f so, adapting to maize and diverging from {O}. scapulalis would decrease the impact of parasitism on {O}. nubilalis at both ecological and evolutionary levels.},
