Which type of wood do Lyctids primarily target?

Lyctids, commonly referred to as powderpost beetles, primarily target hardwoods. Their larvae are known to infest wood species that contain a high starch content, which is typically found in hardwoods such as oak, ash, and hickory. These beetles are particularly attracted to fresh-cut hardwood, where the starch has not yet been fully depleted.

Understanding the behavior of Lyctids is crucial in pest control, as it helps in identifying infestations and applying appropriate treatment methods. The structure and composition of hardwoods provide the nutrients these pests require for their lifecycle, making hardwood species their primary target for feeding and reproduction.

Other types of wood, such as softwoods, are not as susceptible to Lyctid infestations due to their lower starch content and different structural characteristics. The option regarding treated wood is also not relevant since Lyctids do not specifically target treated wood, but rather the natural characteristics of the wood type itself. Thus, the focus remains on hardwoods as the primary source of food for Lyctids.
