The oak timberworm is an economic pest of oaks and other hardwoods in the eastern US. [9] The primary economic losses come from larval boring damage to live standing trees; however, this insect has been known to attack unseasoned lumber, stave bolts, and squared timber. [3] These larval galleries cause structural damage to lumber. [6]
Oak wilt (Bretziella fagacearum), a vascular disease, attacks chinquapin oak and usually kills the tree within two to four years. Other diseases that attack chinquapin oak include the cankers Strumella coryneoidea and Nectria galligena, shoestring root rot (Armillarea mellea), anthracnose (Gnomonia veneta), and leaf blister (Taphrina spp.).

The extent of the impact depends on characteristics of both the pest and host tree. [10] Pests differ in their means of attack and extent of damage. For example, defoliating insect (spongy moth) may weaken trees but not directly cause mortality, while boring insects (emerald ash borer) can often cause serious damage.
The canyon live oak (Quercus chrysolepis) and silverleaf oak (Quercus hypoleucoides) are also affected.
