As for parasitoids, invading hosts are first attacked at low rates by a species-poor complex of mainly generalist species. Over the years parasitoid richness may increase either because the invading host continuously encounters new parasitoid species during its spread (geographic spread-hypothesis) or because local parasitoids need different periods of time to adapt to the novel host (adjustment-hypothesis). Both scenarios should result in a continuous increase of parasitoid richness over time. Our results show that the overall parasitism rate increases as a function of host residence time as well as geographic and climatic factors, altogether reflecting the historic spread of C. ohridella. However, parasitism rates of C. ohridella are still very low. Moreover the parasitoid complex lacks specialists.
