KEANEKARAGAMAN HYMENOPTERA PARASITOID YANG BERASOSIASI DENGAN TANAMAN KELAPA SAWIT PADA FASE PERTUMBUHAN YANG BERBEDA DI PT. MOPOLI RAYA RANTAU ACEH TAMIANG

Hymenopteran parasitoids are biological control agents that contribute mortality to economically important pests of oil palm plantations. In this research we investigated the diversity and abundance of Hymenopteran parasitoids at PT. Mopoli Raya, Aceh Province, Indonesia. Data were collected by adopting a purposive sampling method in mature and immature plantations by using light trap, malaise trap , and yellow-pan trap. Specimens were identified at Universitas Syiah Kuala and final taxonomic confirmation was conducted at Gadjah Mada University. We found that the species richness and evenness of the Hymenoptera parasitoid species in mature oil palm plantations tended to be higher than in immature plantations. It is suspected that in immature oil palm plants
