HABITAT TYPE EFFECTS ON INSECT POLLINATOR SPECIES RICHNESS AND ABUNDANCE IN JAMBI OIL PALM PLANTATIONS

The objective of this study is to examine the impact of varying habitat types on the species richness and abundance of insect pollinators in oil palm plantations. The research was conducted in the village of Bajubang, Batanghari district of Jambi in two distinct habitats (a wet habitat adjacent to a river and a dry habitat located farther from the river). The experimental plot size was 50 x 50 m, with four replicates, and 20 x 10 m plots for flowering plants. Insect pollinator abundance was surveyed prior to and following the introduction of flowering plants. A total of 599 individuals, 52 species, 8 families and 3 orders (Hymenoptera, Lepidoptera and Diptera) were collected. The results indicate that habitat type (dry or wet) influences species richness but not abundance. The dominant insect pollinator species identified were Ypthima philomela, Nomia strigata, and Apis cerana.
