The potential of longhorn beetles (Coleoptera: Cerambycidae) as bioindicators at IPB Dramaga Campus

Abstract Insects such as longhorn beetles play a crucial role in the environment as they serve as indicators of ecosystem balance. Longhorn beetles are commonly utilized as bioindicators for assessing ecosystem damage due to their sensitivity to environmental changes. This research aims to analyze the presence of longhorn beetles as potential bioindicators in several stands at IPB Dramaga Campus, namely in the Segitiga Silvikultur (SS), Arboretum FAHUTAN (AF), and Taman Hutan Kampus (THK). The research method employed Artocarpus traps to capture longhorn beetles. The results indicate that the highest abundance of longhorn beetles was found in the THK plot due to the availability of sufficient food sources. The abundance of longhorn beetles was recorded at 27 individuals comprising 5 species, with Acalolepta rusticatrix dominating all research plots. Several factors influencing the presence of longhorn beetles include climatic factors, tree diversity, and human activities. Some longhorn beetle species have the potential to serve as bioindicators of forest ecosystem changes due to their distinctive habitats, such as Sybra fuscotriangularis, Epepeotes luscus, Pterolophia sp ., and Ropica marmorata .
