Rapid ʻŌhiʻa Death is a fatal disease caused by Ceratocystis lukuohia and C. huliohia that are decimating Hawaiʻiʻs keystone trees species, ʻōhiʻa (Metrosideros polymorpha). We developed practical and effective decontamination practices for both cultured C. lukuohia and C. huliohia as well as Ceratocystis spores embedded in ambrosia beetle frass (fine particles of macerated wood or boring dust, beetle parts, and feces). This data release includes data and metadata containing decontamination results of ambrosia beetle (Coleoptera: Scolytinae) frass contaminated with Ceratocystis lukuohia propagules using various laboratory and household disinfectants.
