Honeydew-mediated indirect interactions: magnet and spillover effects of an invasive willow–aphid complex.

Abstract

Abundance and richness of insect pollinators that fed on or collected the honeydew excreted by the giant willow aphid on invaded willows. Then, to assess associational effects, we compared the abundance and species richness of floral visitors with a potential pollinator role (hereafter pollinators) on S. chilensis located near and far away from the willow-aphid complex.
