ABSTRAK
Penelitian tentang tabel kehidupan Epilachna vigintioctopunctata F. (Coleoptera: Coccinellidae) pada Tanaman Terung (Solanum melongena L.) telah dilakukan dari bulan Juli sampai Desember 2013 dengan tujuan untuk membuat dan menganalisis tabel kehidupan E. vigintioctopunctata dan mengidentifikasi faktor-faktor penyebab kematian stadium pradewasanya. Penelitian ini menggunakan metode observasi langsung. Pengamatan terhadap variabel tabel kehidupan dilakukan pada rumah kawat sedangkan identifikasi predator dan parasitoid dilakukan di Laboratorium Zoologi, Jurusan Biologi Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Syiah Kuala. Variabel yang diamati adalah natalitas, mortalitas, dan kelulushidupan E. vigintioctopunctata. Hasil penelitian menunjukkan bahwa telur E. vigintioctopunctata yang berhasil mencapai dewasa sebesar 1,16%. Persentase mortalitas tertinggi terjadi pada fase telur (86,02%), diikuti oleh larva (12,59%), dan pupa (0,23%). Selanjutnya, nilai total mortalitas generasi (Kvalue) adalah 4,93. Faktor-faktor yang menyebabkan mortalitas stadium pradewasa E. vigintioctopunctata yaitu: parasitoid, predator, daun dimakan herbivor, hujan, dan gagal menetas. Tiga jenis predator yang menyerang telur dan larva E. vigintioctopunctata yaitu Manthis sp. (Mantidae), Oxyopes sp. (Oxyopidae), dan Bathippus sp. (Salticidae). Parasitoid yang menyerang telur E. vigintioctopunctata hanya satu jenis yaitu Tetrastichus sp.

Kata kunci: Epilachna vigintioctopunctata, tanaman inang, predator, dan tabel kehidupan.

ABSTRACT
Research about the life table of Epilachna vigintioctopunctata F. (Coleoptera: Coccinellidae) on eggplant (Solanum melongena L.) was conducted from July to December 2013, in order to construct and analyzed the life table of E. vigintioctopunctata on its host plant, S. melongena and identified the mortality factors of immature stage. Observations of life table were done on the field cage while identification of predators and parasitoids were done in the Laboratory of Zoology, Biology Department, Faculty Mathematic and Natural Science, Syiah Kuala University. The variables in this study were natality, mortality, and survivorship of E. vigintioctopunctata. The results showed that the eggs of E. vigintioctopunctata who reached to adult by 1,16%. The highest percentage of mortality occurred in the egg stage (86,02%), followed by the larval (12,59%), and pupal stages (0,23%). Furthermore, the total mortality generation (Kvalue) of E. vigintioctopunctata were 4,39. Five mortality factors were identified during the study, there were parasitoid, predators, herbivore which ate the egg plant, rain, and failure to hatch. Three species of predators that attacked the eggs and larval stages of E. vigintioctopunctata were Manthis sp. (Mantidae), Oxyopes sp. (Oxyopidae), and Bathippus sp. (Salticidae). Tetrastichus sp. was the only one of parasitoid that found in the eggs of E. vigintioctopunctata.

Keywords: Epilachna vigintioctopunctata, host plant, predators, and life table.
