Data from: Population- and species-based variation of webworm-parasitoid interactions in hogweeds (Heracelum spp.) in the Netherlands

Jeffrey Harvey, Rieta Gols & Paul Ode
In three Dutch populations of the native small hogweed (Heracleum sphondylium), and one of the invasive giant hogweed (H. mantegazzianum), interactions between a specialist herbivore, the parsnip webworm (Depressaria radiella), and its associated parasitoids were compared during a single growing season. We found plant population and/or host plant species-related differences in the abundance of moth pupae, the specialist polyembryonic endoparasitoid, Copidosoma sosares, the specialist pupal parasitoid, Barichneumon heracliana, and a potential hyperparasitoid of C. sosares,...
