| Outline of Final Research Achievements |
Weevil larvae are major pests on seeds of dipterocarps, which dominate tropical rainforests in Southeast Asia. However, species composition of the seed weevils are still unclear due to difficulty in obtaining adult samples by rearing. This study aimed to identify all the weevil species on dipterocarp seeds using DNA barcoding.
We found a new group of Curculio weevils as one of the major dipterocarp seed predators besides Alcidodes and nanophyid weevils already known. Comparing phylogeny of weevils and dipterocarps, we found that species composition of weevils were distinct among dipterocarp genera.
