Understanding the pattern of lepidopteran pest community attacking oil palms and associated parasitoid is very important to develop appropriate biological control strategies. Insects were surveyed by collecting larvae of lepidopteran pests attacking oil palm plantations. Samplings were conducted by diagonal transect walk crossing oil palm blocks. Insects collected from the field were brought into the laboratory and maintained with fresh leaves of oil palm until pupation. Parasitized larvae were intensively observed, and emerging parasitoids were collected for identification. In total, approximately 17 species were identified to attack oil palm by surveying 976 trees from three different age of palm oil plantations. Only 19,98% of which were infested by Lepidopteran pests. Limacodidae was found to be the most specious family inhabiting oil palm plantation of the study area, and Psychidae only represented by two species. Setora niten was recorded to be the most abundant species. Abundance structure of Lepidopteran pests seems to be different for different age of oil palm. S. nitens was found to be dominant in younger oil palm but not in older oil palm. Only four species were found to be parasitized by parasitoid including Birthamula chara, Darna bradley, Darna deducta, Darna trima, and Limantriidae (ulat bulu-3). All parasitoid species attacked the larvae were gregarious belongs to Braconidae and Eulophidae. Euplectrus, gregarious endoparasitoid of Eulophid was found to parasitize D trima. Long term study is needed to understand the complete pattern of host-parasitoid interaction in oil palm plantations.
