The white peach scale is increasingly more common as a pest of fruit and landscape trees. The waxy round coverings that protect overwintering females of this armored scale have orange to yellow centers that appear like tiny fired eggs.
Scale insects are important pests of landscape trees and armored scales are especially nefarious. They remove increasing volumes of sap as populations grow but the symptoms of infestation are initially subtle and these insects are easily overlooked. Yellowing leaves and branch dieback can occur over time.
Crawlers, representing the first of up to three annual generations, emerge from under their scale coverings in May. Later generations can appear from late July to early August and again in early September. Small bands of double-sided tape can be placed around a few infested branches to trap the tiny mobile stage of this insect.
