Bagworm infestation on Shorea balangeran in the degraded peatland restoration plot

Abstract

Abstract Restoration through re-vegetation activities is one of the solutions to recover degraded peatlands quickly. Shorea balangeran is one of the most promising species of Dipterocarpaceae that can be chosen for the degraded peatlands rehabilitation. The bagworm is one of the potential pests to damage the S. balangeran in Ogan Komering Ilir (OKI) regency. The objective of the study was to provide various information about bagworm insect pests on S. balangeran. Two measuring plots of 50 x 32 m laid on 2017 planted S. balangeran in agrosilvofishery based on integrated peat restoration pilot project. The variables observed were the number of attacked plants to calculate incidence and the number of attacked leaves in each observation unit (tree) using a scoring system to calculate the intensity. The data obtained were analyzed by descriptive quantitatively. The results showed that there were two species of bagworm in S. balangeran. The incidence of both bagworms was quite high, but the intensity of damage was still relatively mild. However, control measures for bagworms still need to be carried out.
