rtalitas 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.
