Notes: [Proceedings of the Second International Symposium on Biological Control of Weeds, Paul H. Dunn (Ed.), 4-7 October 1971, Rome, Italy.] The conflict refers to an insect characterized as a pest by some but as an agent of biological control by others. Cryptolaemus montrouzieri on the mealybug Dactylopius tomentosus and the Opuntia spp. is one of the examples given.
