Which of the following beetles is known to not re-infest?

The powderpost beetle is recognized for its unique behavior in relation to wood infestation. Once it has completed its life cycle, it does not re-infest the same wood material. The larvae of powderpost beetles develop in the wood, and upon maturing, they exit to mate and lay eggs on new wood sources rather than returning to re-infest previously infested wood. This characteristic makes the powderpost beetle distinct compared to other beetles that may have repetitive cycles of infestation.

In contrast, the longhorned beetle, metallic wood borer, and bark beetle can re-infest wood, as their larvae feed and develop within the same wood structure multiple times or over various generations. Hence, the behavior of the powderpost beetle is critical for pest management practices, focusing on ensuring that new wood materials are not introduced to environments where powderpost beetles may have been previously established.
