RED-SHOULDERED SHOT-HOLE BORER
The red-shouldered shot-hole borer, Xylobiops basilare (Say), and other shot-hole borers also injure trees in a devitalized condition. The larvae feed in wood, pupate and emerge as adults through round holes about one-eighth inch in diameter in the bark. Many of these holes may be observed in close proximity to each other.
Control.—Since this insect feeds on dying or dead wood, prunings and dead limbs should be removed from the orchard and burned.
Adequate fertilizer and water will keep trees in a healthy condition and prevent injury by this pest.
