What Is The Cause Of My Tree's Illness?
Pine tips weevils are also known as white pine weevils.
Dangers Of Pine Tip Weevils
White pine weevil larvae kill the terminal leader and the top two to four years of growth on many varieties of spruce, as well as white and Scots pine trees. Damage from white pine weevil can be distinguished from other types of injury by the somewhat curled shape of the leader, sometimes referred to as a “shepherd’s crook”. The curling effect is caused by more weevil larvae feeding on one side of the leader.
How A Basic Diagnoses Is Made
The adult weevils overwinter on the ground, protected and insulated by the fallen needles. Once they warm up, the weevils move up to the tops of the trees in late afternoon or early evening and feed on the terminal leader. Damage from white pine weevil can be prevented by spraying the upper trunk and terminals of spruce and pine in early to mid-April and again two weeks later.
