Background and aims: Ligaria cuneifolia (Loranthaceae) has a wide geographic distribution from Peru to the center of Argentina and Uruguay. It inhabits three disjunct regions, one along the Andes, Sierras Centrales of Argentina and towards the East in Uruguay and south of Brazil. The objective of this study was to determine the host range of Ligaria cuneifolia in all the distribution range; and to analyze host use in each of the geographic regions (Andes, Center and East).
M&M: hosts use and geographical distribution of Ligaria cuneifolia was recorded on the basis of specimens deposited in herbaria.
Results: A total of 35 native host species were recorded as hosts. In addition, 11 non-native host species were recorded in all area. The genera with higher number of records were Schinus, Prosopis, Geoffroea, Larrea y Vachellia.
Conclusions: Host use was not directly related to geographic area. The Andes region was the one that had the most host diversity at the species, genera and family level.
