Composición y diversidad de avispas Agaonidae (Hymenoptera: Chalcidoidea) en tres especies de Ficus L. (Moraceae) del Parque Mirador Sur en Santo Domingo, República Dominicana

Abstract

The composition and diversity of wasps species was determined in three species of Ficus (Moraceae) in the Mirador Sur Park, a green area in the city of Santo Domingo, from May to July 2014. We sampled 16 trees corresponding to the species: F. crassinervia Desf. ex Willd (n = 8), F. crocata (Miq.) Miq. (n = 6), and F. citrifolia Mill. (n = 2). 159 syconia were examined in which 11,452 wasp specimens, 30,256 flowers, and 16,337 seeds were counted. A total of 19 wasp morpho-species were indentified belonging to three families, five sub-families, and 10 genera. Several diversity indices were measured. The genus Pegoscapus Cameron, 1906 was the unique pollinator found, recording one morpho-species on each of the species of Ficus. Results revealed that the dominant species was Pegoscapus sp. 2 present in F. citrifolia due to its abundance. The number of individuals of pollinating wasps varied between species of Ficus. The highest wasp richness was recorded on F. crassinervia (17 species). The importance of each wasp morpho-species in its interaction with Ficus is discussed, as well the possible reasons of diffrences in wasp species richness between the species of Ficus.
