The abundance of parasitoids on plants that harbor their monophagous herbivorous host often correlates with host numbers. However, when hosts are polyphagous, the species-specific characteristics of the plants can affect parasitoid abundance as well. We asked whether parasitoids that attack a polyphagous host aggregate on individual plants with high host densities, and whether plant-related factors also account for the parasitoids’ abundance on the plants.
