The results showed that the functional response of C. stephanoderis fitted with the Hollingis functional response type II. The attack rate (a1) of C. stephanoderis for both of the prepupal and pupal stages of CBB was 0.042 individuals per hour. The handling time (Th) of C stephanoderis on prepupal stage was longer than on pupal stage of CBB, 10.8 and-9.1 hours/individual respectively Keywords: coffee berry borer - parasitoid - functional response
