| Abstract: | Bamboos are known as long-living monocarpic plants that exhibit synchronous flowering at long intervals. It has been reported that florivory has a critical effect on their seed production in bamboos, especially in small scale flowering patches. In this study, we aimed to determine species composition and life history of florivorous insects in multiple bamboo species. We collected the inflorescences of 12 bamboo species from 15 sites in Japan from 2017 to 2019 and recorded insect assemblages found in the flowers. Five different insect species were observed to feed on the flowers of bamboo species. Among these, the larvae of two Dicraeus species were the most widely observed florivorous insects of the bamboo species. The other insects included the larvae of Cecidomyiidae sp., which was frequently observed on Sasa species, and the other two insects were Epuraea submicrurula, and Dimorphopterus japonicus. These insects were oviposited on the florets during the budding period. In addition, predators and parasitoids were found in the bamboo flowers. Our findings suggest that the bamboos flowers were mainly consumed by dipteran larvae. Insect species composition and frequency varied among bamboo species and sites. Comparing the frequency of the florivorous insects among bamboo flowering patches, including mass flowering patches, in different areas is needed in future studies. |
