The dogwood borer (DWB), a native clearwing moth, can be found from southeastern Canada to Florida, and as far west as the Mississippi. The insect has a wide host range including dogwood, pecan, oak, plum, and apple. The DWB has one generation per year throughout its geographic distribution. On apple DWB larvae feed primarily in burrknot tissue on clonal rootstocks. Burrknots are aggregations of root initials which can develop on the above ground portion of the rootstock (Fig. 1 ). All commercial dwarfing and semi-dwarfing rootstocks have a tendency to develop burrknots.
