Gloomy scale is an armored scale insect pest of ornamental trees, most commonly red maple trees. These pests are much more abundant and damaging in urban landscapes than natural forests. This insect note describes an integrated pest management approach to identifying, monitoring, and managing these pests.
Japanese maple scale is an exotic, armored scale insect pest of several ornamental trees and shrubs, most commonly in urban landscapes. This insect factsheet provides an integrated pest management approach to identifying, monitoring, and managing Japanese maple scale.
A foundation of IPM in urban landscapes is to put the right plant in the right place. This reduces plant stress and thus the long term costs of pest management. Impervious surface cover is linked to red maple condition and scale insect infestations. This publication describes impervious surface thresholds to use when selecting sites for planting red maples in urban landscapes.
Impervious surface cover increases tree stress and reduces tree condition. We developed an impervious surface threshold to help tree care professionals select planting sites where red maples will thrive. In this publication we describe how to estimate impervious surface cover, on site, with the Pace to Plant technique.
