Effects of Garden Attributes on Ant (Formicidae) Species Richness and Potential for Pest Control

Urban Farm DB summary

This study investigated ant (Formicidae) species diversity in relation to garden attributes at three gardening sites in Ann Arbor, Michigan, along with predation experiments testing biocontrol of Cabbage Looper moths and Squash Bugs. It sampled 19 ant species from 12 genera, finding that soil texture, intense tilling and distance from less-disturbed areas significantly reduced species richness, with less-tilled plots averaging nearly double the species of tractor-tilled plots. Ants consumed Cabbage Looper eggs and larvae, and the authors conclude that reducing disturbance in and around gardens can promote ant biodiversity and beneficial pest predation.
