Viable Ceratocystis Propagules in Frass

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: July 16, 2025 | Last Modified: 20200827
These data include Ceratocystis culture viability results from ambrosia beetle (Coleopetera: Scolytinae) frass. Frass is defined as fine particles of macerated wood or boring dust, beetle parts, and feces. Frass was collected from individual ambrosia beetle galleries in Ceratocystis-infected ʻōhiʻa (Metrosideros polymorpha) trees on Hawaiʻi Island, a phenomenon referred to as Rapid ʻŌhiʻa Death (ROD). We recorded the height at which these beetles produced frass, how long we collected frass from galleries, and the total number of culturing tests from individual galleries.
