Aphidus ervi is sold commercially to control foxglove aphid but actual control in ornamental greenhouse crops is limited. This study investigates if the plant-location preferences of foxglove aphid play a role, and if use of the wasp increases aphid dispersal.

Data contains number of aphids attacked by A. ervi, number of aphids dispersing in the presence of A. ervi, etc. The government will use this data to guide further experiments with this natural enemy (release rates, etc).
