These data contain the results of ʻōhiʻa seedlings challenged with different ambrosia beetle (Coleoptera: Curculionidae) species that were exposed to either Ceratocystis lukuohia or Ceratocystis huliohia in culture. Disease development, viability, and DNA confirmation data were recorded.
These data contain the documentation of ambrosia beetle (Coleoptera: Curculionidae) attack on healthy ʻōhiʻa trees. Beetles were collected on sticky cards.
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.
These data contain the documentation of culturing results of Ceratocystis lukuohia and Ceratocystis huliohia from ambrosia beetle (Coleoptera: Curculionidae) bodies. Beetles were collected from bolts (tree stem sections), sticky cards affixed to ʻōhiʻa trees in the field, and cross-vein panel traps deployed in the field. Beetles were cultured to detect the presence of fungi, confirmed morphologically, then further confirmed for DNA by quantitative polymerase chain reaction (qPCR).
These data contain the gps coordinates of ʻōhiʻa trees used in documenting the visitation of ambrosia beetles to ʻōhiʻa trees in two different experiments. The diameter at breast height (DBH; cm) of the trees were also recorded.
