Pomegranate fruit borer Deudorix epijarbas (Moore) is one of the serious pests of pomegranate. In Himachal Pradesh, the extent of loss varies between 50-90%. Various modules including insecticides and biopesticides were evaluated using 3 sprays at 21 days interval, initiating the first spray when 1-2 fruits in orchard showed signs of infestation. Among 19 modules, module M18 (cyantraniliprole-cyantraniliprole-cyantraniliprole (0.0075%)) resulted in maximum fruit yield (7.37kg/ha) but its incremental benefit cost ratio (IBCR) value was low (3.42:1). To reduce problems due to repeated use of same insecticide, insecticides and biopesticides need to be used in rotation. Modules including first and second spray of biopesticides, were economically non-viable due to IBCR <1. Among biopesticides, only M14 (3 consecutive sprays of spinosad) showed encouraging results with infestation of 16.85% and IBCR of 5.75:1.
