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.
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.
Maple spider mites are a common arthropod pest of landscape and nursery-grown maple trees, most commonly red maple and red maple x silver maple hybrids (Freeman maples). This pest factsheet provides an integrated pest management approach to identify, monitor, and manage maple spider mites.
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.
This Insect Note describes the biology and management of greenstriped mapleworm, a caterpillar pest of maple trees.
Healthy plants are important components of urban landscapes. These plants, however, are subjected to attacks by a myriad of pests while they are being grown in a nursery or maintained in a landscape. The ultimate goal of a successful ornamental plant pest management program is to improve the quality of plants (nurseries and greenhouses) and plant care services (landscape care operations) while minimizing pesticide use and the negative impacts of pesticide use to the environment, workers, clients, and other non-target organisms. To do so, ornamental plant growers and landscape care professionals have to understand the basic operating principles of integrated pest management, or IPM. The results of IPM can be spectacularly effective when well designed and executed.
This factsheet discusses the biology and control of ocellate gall midges, which cause red and yellow spots on the surface of red maple leaves.
Fuller rose beetle is a generalist herbivore pest of many ornamental trees and shrubs. These pests feed are primarily nocturnal and feed on leaves, although they are not often economically damaging. This insect note describes an integrated pest management approach to identifying, monitoring, and managing these pests.
