Granara de Willink, M.C., & Claps, L.E. 2003 [Scale insects (Hemiptera: Coccoidea) present in ornamentals in Argentina.] Cochinillas (Hemiptera: Coccoidea) presentes en plantas ornamentales de la Argentina.. Neotropical Entomology 32(4): 625-637.
Notes: Many native and exotic plants are cultivated in urban environments, where they provide shade and appeal to our aesthetic sensibilities. Almost no research has been done on the Coccoidea associated with ornamentals in the Neotropics, although they seem especially well-adapted for survival in urban ecosystems. The objective of this study was to provide information about some scale insect families that attack ornamentals in Argentina. Collections of scale insects in Argentina, and new materials collected in the field or sent for identification by colleagues throughout the country were evaluated. Ninety species of Coccoidea, belonging to 8 families and 53 genera, were identified. Fifty-two species of Diaspididae, 15 species of Pseudococcidae, 18 species of Coccidae, and only one species of Asterolecaniidae, Eriococcidae, Lecanodiaspididae, Margarodidae, and Ortheziidae were found. Seventy-one species were cosmopolitan and 19 were endemic. Approximately 190 ornamental species in many different families were affected. A list of the scale insects in alphabetical order, hosts, distribution, economic importance, and relevant bibliography is provided.
