The oil palm leaf webworm is most active from October to March, with population densities varying between study periods. Natural enemies like the larval parasitoid Dolichogenidea hyposidrae and pupal parasitoid Brachymeria albotibialis help control the pest, with high levels of parasitism observed. In oil palm-cocoa intercropping systems, lower pest density and damage were noted, along with increased natural enemy activity. Insecticides such as deltamethrin, lambda cyhalothrin, chlorantraniliprole, thiodicarb, and fipronil were effective in managing the pest in oil palm gardens.
