Attackers
Insects that bore into stems and branches
of trees and shrubs can cause considerable damage or death to those
plants. For the most part, these borers attack only plants that
are weakened by environmental stress, i.e. drought or flooding,
or cultural factors such as mechanical injury from weed trimmers
or lawn mowers. This occurs because the plant's normal defenses
are diminished as a result of the stresses imposed on the plant
by these external factors.
Maintaining optimal growing conditions for
plants in landscapes and nurseries, and proper maintenance practices
such as pruning and nutrient management can minimize attacks by
insect borers.
