Blueberry stem borers and thrips are two insects that can damage blueberry plants by scarring and/or tunneling through the stems. Click on the links below to learn more.

Blueberry stem borers are slender, elongated beetles with light brown or yellowish bodies. At first, the larvae tunnel upward within the cane, then reverse direction and burrow toward the crown of the plant.

Thrips are small, narrow insects with "fringe wings." Damages they can cause blueberry bushes include shoot stunting, leaf deformation, shortened internodes and stem scarring.
