We report here abundances of adults and nymphs of Euterpnosia chibensis okinawana Ishihara captured by emergence traps installed on the forest floor of the Yambaru with the operation of the improvement cutting of natural forests. Thirteen operated forests (1-22 years passed after the operation) and four non-operated forests were selected as study plots and five traps covering 1.8squarem per forest were installed. Nine adults and 12 nymphs of E. chibensis okinawana were collected from eight operated forests (1-22 years passed after the operation) and two non-operated forests. One to seven individuals were collected per forest. Influence of the operation to abundance of E. chibensis okinawana was unclear. No relationship was found between the forest ages and abundance of cicadas collected.
