Bronze birch borer primarily infests which genus of trees?

• A. Birch
• B. Maple
• C. Oak
• D. Pine

Answer: (A)

Bronze birch borer shows a strong host preference, attacking only birch trees. The beetle’s life cycle centers on Betula species, with larvae feeding under the bark and tunneling through the cambium, which interrupts nutrient flow and can girdle branches or the trunk. Because birch is the genus it infests, it does not typically target maples, oaks, or pines. In practice, look for signs like canopy thinning and bark damage on birch trees to identify this pest.
