McFadyen, R.E., & Tomley, A.J. 1978 Preliminary indications of success in the biological control of Harrisia cactus (Eriocereus martinii Lab.) in Queensland.. Proceedings of the first conference of the Council of Australian Weed Science Societies Council of Australian Weed Science Societies Frankston, Victoria, Australia 446 pp.

Notes: [Conference held at National Science Centre, Parkville, Victoria 12-14 April 1978.] Of 17 species of insects that had been found feeding on Harrisia cactus (Eriocereus martinii) in South America, 4 were sent to Queensland during a biological control programme that began in 1973. An undetermined species of Cactoblastis died out in quarantine, but Alcidion cereicola Fisher, Hypogeococcus festerianus (Lizer y Trelles), and Eriocereophaga humeridens O'Brien were released in the field and the first two became widely established. Three years after the initial releases, damage to the cactus at the release sites was severe, growth and seed formation were greatly reduced, and the indications were that successful biological control would be achieved.
