Claps, L.E., & de Haro, M.E. 2001 Coccoidea (Insecta: Hemiptera) associated with Cactaceae in Argentina.. Journal of the Professional Association for Cactus Development 4: 77-83.

Notes: Coccoidea (Insecta: Hemiptera), commonly called "cochineal insects", "mealybugs" or "scale insects", show a marked sexual dimorphism and display a high degree of adaptation to the parasitic life. They have adapted to become a specialised group of small phytophagous insects no more than a few millimetres in length. This paper provides more information with regard to Coccoidea species and their hosts recorded on Argentinean cacti. Six species of Dactylopiidae: Dactylopius austrinus De Lotto, D. ceylonicus (Green), D. confertus De Lotto, D. coccus Costa, D. salmianus De Lotto, and D. zimmermanni De Lotto; four species of Diaspididae: Abgrallaspis cyanophylli Signoret, Aonidomytilus albus (Cockerell), Diaspis boisduvalli Signoret, D. echinocacti (Bouche); and two species from Pseudococcidae; Hypogeococcus festerianus (Lizer y Trelles) and H. pungens Granara de Willink, are reviewed. The characterisation and importance of the three registered families are also provided.
