Abstract

In urban settings, Pseudaulacaspis pentagona infests mulberry Morus spp. trees in disturbed landscape habitats (roadsides, parking lots) but not trees in forested habitats (woodlots). Populations of P. pentagona are contagiously distributed. The patchy distribution of P. pentagona in Maryland is best explained by the combined influences of natural enemies and plant water relations. P. pentagona infests a small subset of mulberry trees in the urban landscape that are without water deficits and free of generalist invertebrate predators. -from Authors
