Abstract
Aren (Arenga pinnata Wurmb Merr.) is an annual plant belonging to the Palmae family that is commonly found in the tropics. In Indonesia, the estimated area of aren palms reaches 61,924 ha. The development and utilization of aren palm as an agribusiness commodity have been going on for quite a while. All parts of the plant, starting from the roots, stems, leaves, palm fiber, sap, starch, and fruit, are useful for the community. The cultivation of aren palm supports the high diversity of insects around it. There are 250,000 species of insects in Indonesia that play an important role in the ecosystem. The diversity of insect species and their role in sugar palm plants and surrounding vegetation is not widely known. Especially in Tanjung Miring Village. Therefore, this study was conducted to determine the diversity of insect species and their roles in sugar palm plants and surrounding vegetation in Tanjung Miring Village, Sungai Rotan District, Muara Enim Regency, South Sumatra. The research was conducted using the purposive sampling method. Samples of plants observed were selected intentionally with the criteria of aren palm plants that were flowering. The research was conducted by installing traps to determine the types of insects found on palm plants and surrounding vegetation. The traps used were the pitfall trap and the yellow sticky trap. The trapped insects were taken in the morning at 07.00 WIB. Insect sampling was done once a week. Observations were made by observing and calculating the diversity of insect species caught in the trap. Insect specimens obtained were identified; the morphological characteristics observed were body color, caput, antennae, thorax, abdomen, front wing color, and limbs. The results of research conducted on sugar palm plantations in Tanjung Miring Village, Sungai Rattan Subdistrict, Muara Enim Regency, obtained 11 orders of 28 insect species. Among the insects in the Hymenoptera order are Apis sp.., Heterotrigona itama, and Vespa affinis. Coleoptera are Luperaltica nigrialpis, Languria, Episcapha Gorhami, Crioceris duodecimputata, Onthophagus vulpes, Cicada bothrogonia, Eleodes fusiformis, Chalepus walshi, Rhynchophorus ferrugineus, and Paederus fuscipes. Hemiptera contained Amblypelta sp., Zelus longipes, and Ectomocoris atrox. Diptera were Scholastes cinctus, Bactocera sp., and Nephotoma guestafalica. The lepidoptera were Cupha erymanthis, Ypthima baldus, and Ideopsis vulgaris. Isoptera found C. curvignathus and Copthotermes sp. Orthoptera found Melanoplus bivittatus and Nisitrus vittatus. Dermaptera found Chelisoches morio species. Odonata found Neurothemis fluctuans. Tysanoptera contained Thrips sp., and there was one species of collembola. Four roles of insects were found in the flowers of palm trees, consisting of pollinators, decomposers, phytophages, and natural enemies. The conclusion of this study was the identification of several insect species, consisting of 11 orders. Species obtained from 20 samples of palm trees in 5 weeks of observation amounted to 729 insects. Insects that act as pollinators and natural enemies are most dominant in sugar palm trees. The highest insect diversity index was obtained in sweep net traps, which were classified as medium. The highest evenness index is obtained in mechanical traps, which is classified as a high category, and the highest dominance index is obtained in pitfall traps and sweep net traps, which is classified as a high category.
