Peach Tree Biography
The peach tree borer (also called the peach crown borer) is the most destructive insect pest of peach, cherry, plum and other stone fruits (Prunus spp.) in Colorado. The insect feeds under the bark of the tree, where it cuts deep gouges. When abundant, peach tree borers seriously weaken and even kill trees. In most areas of the state it is necessary to periodically control this insect to maintain tree vigor.
The entire life cycle of the peach tree borer requires one year to complete. The immature (larva) stage produces tree damage. Upon hatching from the eggs, young larvae immediately tunnel into the sapwood of the tree, usually through cracks and wounds in the bark. Larvae continue to feed and develop until the onset of cold weather. Most activity occurs a few inches below ground on the trunk and larger roots. The Insects spend the winter as partially grown larvae below ground under the bark.
With the return of warmer weather in early spring, the larvae again feed on the tree. Injury is most extensive at this time because the maturing Insects feed more. The larvae finish feeding and change to the pupal stage in late May through early July. Pupation occurs in a cell made of silk, gum and chewed wood fragments located just below the soil surface.
