Scale insects are common pests of landscape trees and shrubs that are often overlooked when scouting. Scales can be responsible for chlorosis, branch die-back, and ultimately, plant death. Scales are broadly categorized as either soft scales or armored scales. Soft scales produce a soft, cottony, powdery, or waxy substance that cannot be separated from the scale body. Common soft scales in Georgia include Indian wax scales, Florida wax scales, brown soft scales, oak lecanium scales, magnolia scales, cottony maple scales, cottony camellia scales, cottony cushion scales, and azalea bark scales. Armored scales have a hard, shield-like cover that is not attached to the body of the insect. Common armored scales in Georgia include tea scales, euonymus scales, obscure scales, false oleander scales, juniper scales, and gloomy scales.

The red-headed flea beetle is a serious insect pest in ornamental nurseries. It is also referred to as the “cranberry flea beetle” in cranberry and blueberry systems in the Northern U.S. The adult beetle causes serious feeding damage to the foliage of a variety of woody and herbaceous container plants in nurseries. As the name suggests, the flea beetle jumps when disturbed, similar to a dog flea. A native pest, this insect is present in central and eastern U.S. regions.
