Analysis of Soil Arthropod Composition and Diversity in Oil Palm (Elaeis Guineensis Jaqc.) and Rubber (Hevea Brasiliensis). In: Herlinda S et al.

Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Oil palm (Elaeis guineensis) and rubber (Hevea brasiliensis) are very important plants in the industrial sector. In oil palm and rubber plantations, many soil Arthropods are found. The diversity of soil Arthropods in oil palm and rubber plantations plays a role in maintaining soil structure balance and can preserve soil fertility. The purpose of this research was to determine the types of soil Arthropoda present in oil palm and rubber plantations at Sriwijaya University Plantation. The method used is diagonal sampling at several predetermined locations. The survey was conducted by setting up pitfall traps in each designated plot. The results of the research conducted showed that the composition and diversity of soil arthropod species in oil palm and rubber plantations included predatory arthropod species, insect pests, and neutral insects. Six predatory arthropod species were found in oil palm plantations and five species in rubber plantations, including Odontoponera denticulataI, Oxyopes sp., Anoplolepis gracilipes, Euborellia annulipes, Pardosa sp., and Walckenaeria furcillata. There were three species of insect pests in oil palm plantations and two species in rubber plantations, including Spodoptera litura, Velarifictorus micado, and Trilophida annulata. Neutral insects found in oil palm plantations totaled 7 species, while in rubber plantations, there were 5 species: Mesomorphus gridelli, Ascocyrtus sp., Pseudosinella sp., Pycnocelus surinamensis, Genocephalum sp., Entomobrya unostrigata, and Blattella germanica. Eight orders of soil-dwelling arthropod insects were found in oil palm and rubber plantations: Hymenoptera, Araneae, Dermaptera, Coleoptera, Lepidoptera, Orthoptera, Collembola, and Blattodea.]]>
