Abstract

Abstract: Indonesia has the largest mangrove ecosystem in the world, covering 3,364,080 ha (National Mangrove Map, 2021), consisting of dense mangroves (97%), moderate (5.60%), and sparse (1.62%). This study aimed to analyze the density of predator and pollinator insects in relation to mangrove vegetation structure in Marga Sungsang Village and Sungsang IV Village, Banyuasin Regency, South Sumatra. The research employed a quantitative descriptive method through in-situ surveys using three sampling techniques: hand collecting, chemical knockdown, and yellow trap. Sampling plots of 10 × 10 m² were established within transects of 100 × 50 m², selected by purposive sampling. The results showed that predator insects dominated the mangrove ecosystem with 90.13%, while pollinators accounted for only 9.87%. The comparison of insect densities among locations (A:B:C = 13.76 : 8.31 : 5.92 individuals/stand) indicated that the more complex the vegetation structure, the higher the insect density and diversity. The interaction between mangroves and insects forms a reciprocal relationship, where vegetation provides food and habitat, while insects contribute to predation and pollination, thus maintaining ecosystem balance. In conclusion, vegetation structure and composition significantly influence insect density in the Sungsang mangrove ecosystem, supporting biodiversity and ecological stability. Keywords: predator insects, pollinator insects, mangrove, vegetation structure, insect diversity.
