This data release includes metadata and tabular data that documents the response of ohia (Metrosideros polymorpha) and ambrosia beetles (Curculionidae, Xyleborini) following the intentional inoculation of healthy ohia to Ceratocystis lukuohia, one of two fungal pathogens that causes Rapid Ohia Death (ROD). Ohia were inoculated with the ROD pathogen at three sites differing in elevation on the Island of Hawaii during January and June 2019. Inoculated and control trees were monitored for changes in foliage condition, beetle attack rates, beetle species composition, and the viability of the fungi within the tree through August 2021. These data are represented in the following seven files: 1) descriptions of trees, 2) tree conditions and the presence of beetle galleries, 3) beetles collected in boring dust traps (BDTs), 4) viability of fungi in beetle frass, 5) beetles collected on sticky traps, 6) descriptions of felled trees, and 7) beetles emerging from felled trees.

This data release includes metadata and tabular data that describes study trees felled to examine the entire length of their boles for the presence of viable Ceratocystis lukuohia and moisture content of the wood. The felled trees were those inoculated at the Waiakea Forest Reserve (WAI) study site on 10 January and 24 June 2019. The trees were felled and assessed on 18 August 2021, the last day of the field portion of the study.

This data release includes metadata and tabular data that describes changes in tree foliage condition and attack rates of beetles on trees inoculated with Ceratocystis lukuohia and on untreated, control trees during 10 January 2019 - .12 August 2021.

These data contain the study site locations and elevation information where bolts (tree stem sections) infected with Ceratocystis lukuohia and/or C. huliohia were collected on Hawai'i Island.

This data release includes metadata and tabular data that describes ambrosia beetles that were collected on sticky traps placed on trees inoculated with Ceratocystis lukuohia and on control trees which were not inoculated with the fungus. The dataset includes beetles identified by species and the date on which they were collected. Two sticky traps were placed on each tree.

This data release includes data and metadata documenting Ceratocystis viability, moisture content, and beetle activity in felled and tarped ʻōhiʻa lehua (Metrosideros polymorpha) trees previously having been determined to be infected with either Ceratocystis lukuohia or Ceratocystis huliohia, the fungi that cause rapid ʻōhiʻa death (ROD).

This data release includes metadata and tabular data that describes the ambrosia beetle species found along the entire length of the bole of trees infected with Ceratocystis lukuohia. Observations were of trees felled on 18 August, 2021, the last day of the field portion of the study. The felled trees were those inoculated on 10 January and 24 June 2019 at the Waiakea Forest Reserve (WAI) site. Felled trees were sectioned into bolts and returned to the lab where beetles that emerged from the wood were collected and identified.

This data release includes data and metadata containing (1) study site locations and elevation where bolts (tree stem sections) infected with Ceratocystis lukuohia and/or C. huliohia were collected on Hawai'i Island, (2) the ambrosia beetle (Coleoptera: Scolytinae) species that were reared from bolts, (3) Ceratocystis spp. viability results from culturing tests of the beetles' frass, (4) frass production estimates from three ambrosia beetle species, and (5) quantitative Polymerase Chain Reaction (qPCR) DNA results of viability subcultures. Data were used in the analysis for the manuscript "Ambrosia beetle communities and frass production in ʻōhiʻa (Metrosideros polymorpha) infected with Ceratocystis fungi responsible for Rapid ʻŌhiʻa Death." Beetles and frass were collected in the lab from Rapid 'Ōhiʻa Death-infected trees from 2018-2019.
