Pollinator insects on sugar palm (Arenga pinnata Merr.) in South Sumatera, Indonesia

Abstract

Abstract Sugar palm production depends heavily on pollinator insects, including some insects related to A. pinnata. This study aimed to identify pollinating insect species, distribution, and biodiversity in four South Sumatran regions. Sweep nets and yellow sticky traps placed around the flowers of sugar palms were used to catch insects once a week. The trap is set up once every 24 hours. In the Ogan Ilir region, pollinating insect species such as Epuraea aestiva, Mystrops costaricensis, Elaidobius sp., Gabrius sp., and Brachypepluis sp. have been found. Apis meliefera, Apis cerana, Poliba occidentalis, Papilio sp., and Drosophila are found in the Musi Banyuasin of Ogan Komering Ilir (OKI). Drosophila, Graphium agamemnon, Appias libythea, Pothantus lydia, Mycalesis perseus, Vespa affinis, Tetragonula laeviceps, Tabanus sp., Aedes albopictus, Neurothemis fluctuans, Ypthima baldus, Cupha erymanthis, and Apis cerana were found in Muara Enim. Additionally, Muara Enim had the highest pollinator population, while Ogan Ilir had the lowest. Observations showed that the yellow sticky trap technique operated more effectively than the sweep net. The community is anticipated to gain from research by learning more about pollinating insects connected to sugar palms, their role in the surrounding ecosystem, and the bioecology of sugar palms.
