DIVERSITY OF INSECTS IN SWIETENIA MACROPHYLLA AND PINUS MERKUSII

Abstract

The diversity of insects at different strata levels can provide insights into species distribution and their roles within these strata. This study aims to analyze the strata levels and insect diversity in Mahagony (Swietenia macrophylla King 1886) and Tusam (Pinus merkusii Jungh et de Vriese) stands in the Educational Forest, Maros, South Sulawesi. Data were tabulated using Microsoft Excel and analyzed for diversity, evenness, and dominance index. Further analysis will be used using XLSTAT with Principal Component Analysis (PCA) version 2021.2.2 to see the relationship between insect distribution. The research showed that S. macrophylla stands had higher insect diversity in the ground layer with a diversity index of 2.10, where most species found were Carpenter ant (Camponotus sp. Emery 1893). Meanwhile, P. merkusii stands have the highest diversity in the canopy layer with a diversity index of 2.47, and the most common insect found in the Thief ant (Solenopsismolesta Say 1836), most of which is found in the ground layer.
