- Association Episyrphus balteatus laid significantly more eggs on cabbage plants infested with a large number of green peach aphids.
- Association Female Episyrphus balteatus laid more eggs on leaves with a high density of aphids within cabbage plants.
- Observation Overlap between aphids and Episyrphus balteatus eggs on cabbage plants was by no means complete.
