These data contain the documentation of ambrosia beetle (Coleoptera: Curculionidae) attack or colonization on healthy ʻōhiʻa trees that were wounded or un-wounded. Beetles are attracted to stressed trees that emit an ethanol scent which was simulated with wounding. Beetles were collected on sticky cards and gallery (tunnels where beetles live) formation was documented.
