| Outline of Final Research Achievements |
Ambrosia beetles (Scolytidae and Platypodidae) are large taxonomic groups in Coleoptera, with diverse breeding systems (e.g. polygamy, and monogamy) and large variations in density (e.g. common and rare species、including insect pests). In this study, seasonal and spatial dynamics of ambrosia beetles on Fagus crenata and Quercus serrata were analyzed from number of species, individuals, and fitness. All the trunks from bottom to top were utilized, suggesting that the differentiation of the species niches at 10 and 11 species in ambrosia beetles occurred to the height of trees and the degree of decomposition on Fagus crenata and Quercus serrata, respectively. There were no difference of fitness evaluated per female among the species on Fagus crenata and Quercus serrata, indicating that all the ambrosia beetles, regardless of density and reproductive systems, potentially would be high density when available enough resource is provided.
