What is the shape of the exit hole produced by Cerambycid beetles?

• A. Round
• B. Oval
• C. Square
• D. Rectangular

Answer: (B)

Cerambycid beetles, commonly known as longhorn beetles, are known for the characteristic oval shape of the exit holes they create in wood as they emerge from their larval stage. This oval shape results from the shape and size of the adult beetles, which typically have elongated bodies and legs. As the larvae bore through wood, they create tunnels to grow, and when they emerge, they leave behind oval holes that reflect their body structure. The oval exit holes are a key indicator for pest control operators and woodworkers, as they signify the presence of these beetles and potential damage to wooden structures. Recognizing the shape of these exit holes is crucial for identifying the pest and determining appropriate control measures.
