Rhynchocoris spp. Hemiptera: Pentatomidae Hemiptera: Pentatomidae Attack citrus fruits Attack citrus fruits Damage: Both the adults and nymphs of this bug suck the juices from young citrus shoots and fruit at night. Young shoots become mottled and their growth is retarded. Attacked fruits show brown patches, and may later become rotten and fall to the ground. Control : malathion 50 per cent emulsion or fenitrothion (available as verthion, agrothion, or folithion-all at 50 per cent emulsion) at 1 1/2 fluid oz. in 4 gallons of water.
