Bronze Birch Borer
Bronze Birch Borer is a close relative to the emerald ash borer but it is host specific to birch trees. Its preferences are the Weeping European birch (Betula pendula), paper birch (Betula papyrifera) and river birch (Betula nigra). Birches make up 1-3% of the estimated tree population within Jamestown. The birches are very attractive trees with the white bark and the weeping branches of the European birch are an added attraction. Unfortunately they are the most susceptible and with age the trees are weakened and attacked by the borer. They attack the upper branches and the larvae borer around the branch and cuts off the vascular system to the upper parts of the tree causing a dieback in the canopy. The borer moves down the branches to the trunk and as with EAB it is almost too late to treat the tree. There are several insecticide treatments that can be used but they can be expensive and offer little hope.
