Notes: [Papers presented at an annual symposium organized by BARC Symposium V Committee; sponsored by and held at Beltsville Agricultural Research Center, MD, May 18-21, 1980.] The introduction of new weed-feeding insects to control native plants is feasible. Dactylopius opuntiae has been introduced to successfully control Opuntia littoralis and O. oricola in Santa Cruz Island, California. Eriococcus orariensis has been introduced to control Leptospermum spp. in New Zealand.
