This research used a purposive sampling method with a sampling technique using pitfall traps placed in three vegetation types (natural forest, shrubs and oil palm plantation). The overall results include 9 orders, 15 families, 26 species and a total of 2,027 individuals per hectare. In natural forests, there were 7 orders, 12 families, 20 species and 853 individuals per hectare, with a diversity index (H') of 2.27 (medium). In shrubs, there were 6 orders, 8 families, 12 species and 715 individuals per hectare, with an (H') of 2.17 (medium). In oil palm plantations, there were 4 orders, 5 families, 9 species and 549 individuals per hectare, with an (H') of 2.03 (medium)]]>
