ABSTRAK Telah dilakukan penelitian tentang kajian parasitoid pada kupu-kupu Graphium doson Felder & Felder (Rhopalocera) di kampus Darussalam dari bulan Agustus sampai Desember 2018. Penelitian ini bertujuan untuk mengidentifikasi, menghitung, dan menganalisis jenis-jenis parasitoid dari setiap stadia pradewasa kupu-kupu Graphium doson. Telur, larva, dan pupa G. doson dikoleksi menggunakan metode observasi pada tanaman Polyalthia longifolia. Data hasil penelitian dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa, dari 236 butir telur G. doson yang telah dikoleksi, 56,36% telur terparasit parasitoid, 35,59% telur menetas menjadi larva G. doson, dan 8,05% telur gagal menetas. Parasitoid yang menginfeksi telur G. doson, yaitu Ooencyrtus sp. (Hymenoptera: Encyrtidae) dan Tetrastichus sp. (Hymenoptera: Eulophidae). Selanjutnya, dari 62 larva G. doson yang dikoleksi, 16,13% larva mengalami kematian karena terinfeksi bakteri. Sementara pada stadia pupa, dari 17 pupa G. doson yang dikoleksi, 23,53% pupa terparasit parasitoid, namun tidak diketahui jenisnya dan 17,65% pupa lainnya mati karena terinfeksi bakteri. Kata kunci: Graphium doson, tanaman inang, parasitoid, Ooencyrtus sp., Tetrastichus sp. dan bakteri. ABSTRACT The research about a study of parasitoid on Graphium doson Felder & Felder (Rhopalocera) in Darussalam campus has been conducted from August to December 2018. This study aimed to identify, calculate, and analyze the types of parasitoid from each stage of the Graphium doson. Eggs, larvae, and pupae of G. doson were collected on Polyalthia longifolia by using observation method. Data were analyzed descriptively. A total of 236 eggs were collected, which 56,36% eggs infected by parasitoid, 35,59% eggs hatched to G. doson, and 8,05% eggs unhatched. Parasitoid which infected eggs of G. doson were Ooencyrtus sp. (Hymenoptera: Encyrtidae) and Tetrastichus sp. (Hymenoptera: Eulophidae). Furthermore, from 62 larvae of G. doson collected, 16,13% of larvae died due to bacterial infection. While on the pupae stage, with 17 pupae of G. doson were collected, 23,53% pupae infected by parasitoid, but unknown types and 17,65% others infected by bacteria. Keywords: Graphium doson, host plant, parasitoid, Ooencyrtus sp., Tetrastichus sp. and bacteria.
