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.
This insect note describes the biology of the Granulate (Asian) Ambrosia Beetle, Xylosandrus crassiusculus, and provides management recommendations.
This Entomology Insect Note focuses on the park bark adelgid, Pineus strobi, pests found on white pines in North Carolina.
This factsheet describes and gives the biology and management of the Southern pine beetle, Dendroctonus frontalis.
This factsheet describes the biology of yellowjackets— small, social wasps that often nest near or in landscapes.
This factsheet describes the biology of the hickory horned devil, Citheronia regalis, the caterpillar of the regal moth. Because hickory horned devils are harmless to humans and are relatively rare, no control measures are needed.
This factsheet describes the biology of the hemlock woolly adelgid, Adelges tsugae, and provides residential management recommendations.
This Insect Note describes the biology and management of greenstriped mapleworm, a caterpillar pest of maple trees.
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 factsheet describes the biology of the pine needle scale insects, Chionaspis pinifoliae, and provides residential management recommendations.
This Entomology Insect Note describes the biology and control of the twolined spittlebug, an insect pest of turf and ornamentals in North Carolina.
This Entomology Insect Note describes the biology and control of the Eastern tent caterpillar in North Carolina.
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.
This factsheet describes the biology of the greater peachtree borer, Synanthedon exitisoa, and provides residential management recommendations.
The larger elm leaf beetle is 3/8 to 5/8 inches long. It is orange with large metallic blue spots. The larvae are up to ¾ inch long and are also orange. (up to 20 mm in length) orange larvae are also conspicuous and easily recognized. The larger elm leaf beetle often suddenly appears in great numbers, does tremendous defoliation for a year or two and then disappears for an indefinite time (perhaps decades). Sometimes groups of larvae can be seen on the soil surface beneath a tree. The beetles overwinter as grubs in the soil. In spring they pupate, and the new adults emerge from the soil in May. There is one generation per year. The adults may survive throughout the summer.
