Effects of an invasive plant on the performance of two parasitoids with different host exploitation strategies

► Study of multitrophic interactions on an invasive and a native plant. ► Emphasis on parasitoid host exploitation strategies. ► Specialist herbivore and larval parasitoid performed worse on the exotic plant. ► Pupal parasitoid performance was similar on hosts from both plant species. ► Effects of invasive plants depend on the species with which they interact.
