Current information on the known distribution of all 18 species (12 species of Crypticerya Cockerell and 6 species of Icerya Signoret) of fluted scale insects (Hemiptera: Monophlebidae: Iceryini) found in South America is provided. A list of known host plants and natural enemies of these species is given and their pest status in South America is discussed. KEY WORDS: Crypticerya, Icerya, Monophlebidae, South America, distribution, host plants. INTRODUCTION species and, when outbreaks occurred on San Andres Island, Colombia, the most common hosts included essentially all The tribe Iceryini (Hemiptera: Monophlebidae) is palm species (Arecaceae), breadfruit (Artocarpus altilis composed by 84 species distributed in five genera, i.e., (Parkinson) Fosberg), Citrus spp., guava (Psidium spp.), all Crypticerya Cockerell, Icerya Signoret, Echinicerya leguminous trees and weeds (Fabaceae), Ficus spp. Morrison, Gigantococcus Pesson & Bielenin, and (Moraceae), Mammea americana L.

Of these, only Crypticerya (Anacardiaceae) (KONDO et al., 2012a). Another species, C. and Icerya are known from South America. Twelve of 27 genistae, has been reported on 80 species of plants, and was described species of Crypticerya and six of 35 species of reported recently in Colombia, where it is considered a pest Icerya have been recorded from one or more South of chili peppers (KONDO et al., 2016). We provide American countries (GARCÍA MORALES et al., 2016). For the information on the distribution and host plants of the Iceryini purpose of this paper, we treat South America as including species found in South America and discuss their economic Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, importance. French Guiana, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela, but exclude the ABC islands, MATERIAL AND METHODS Trinidad and Tobago, and Panama, which are sometimes considered as part of South America. In South America, the The present paper summarizes our current understanding pest iceryine species are commonly called fluted scales of the distribution, host plants, pest status, natural enemies, because the female (often hermaphroditic) produces a white and other information such as biological and taxonomic waxy ovisac marked with longitudinal grooves or flutes. The notes on scale insects of the tribe Iceryini (Hemiptera: species of greatest economic importance in South America Monophlebidae) in South America based on a literature are Crypticerya brasiliensis (Hempel), C. multicicatrices review and personal observations.

All of the above species are polyphagous and attack plant species of economic importance.
