Goeden, R.D., & Andrés, L.A. 1999 Biological control of weeds in terrestrial and aquatic environments.. Handbook of Biological Control: Principles and Applications of Biological Control. Academic Press San Diego et al. 1046 pp.

Notes: The methodology is discussed for carrying out a project of biological control. Conserving and augmenting existing biological control agents is also discussed. More than 80 projects in biological weed control have been carried in the U.S. and Canada and 101 species of weeds have been targeted worldwide for 174 projects. Dactylopius ceylonicus is one of the agents discussed for control of Opuntia spp.
