Cowpea aphids are shiny black with white and black legs. They inject a powerful toxin into the plant while feeding and, when their numbers are high, this can stunt or even kill plants. While feeding, this aphid produces a considerable amount of honeydew upon which sooty mold can grow. Icipe research investigates the use of entomopathogenic fungi as biopesticide and also the use of parasitic wasps.
