ALONSO-HERNANDEZ, Nancy et al. Spatial distribution of braconids (Hymenoptera) records from the state of Oaxaca. Acta Zool. Mex [online]. 2014, vol.30, n.3, pp.564-594. ISSN 2448-8445.

A list of 300 morphospecies of Braconidae from State of Oaxaca is presented, of these 83 species and 146 genera were identified. In the study the spatial distribution of braconid was analyzed, records and data were georeferenced. A Geographic Information System with the species recorded from literature and material deposited in scientific collections was developed. The regions with the highest abundance of genera were Costa, Central Valleys and Istmo, the subfamilies most diverse were represented by Agathidinae and Doryctinae. The vegetation with highest incidence of records was the evergreen tropical forest that included 81 genera, the most representative genera were Heterospilus, Opius, and Bracon. The distribution of Braconidae in warm temperatures represented 85 % of the genera, being the subfamilies Alysiinae, Euphorinae, Doryctinae, and Microgastrinae the most representative. The climate with major presence of braconids was the warm humid and the most abundant subfamilies were Doryctinae and Microgastrinae. In the semi-warm humid climate there were found especially specimens of the subfamily Agathidinae. The parasitoids were distributed from 20 to 2900 m of altitude, but the greatest number of records were found at the height of 736 m and the genus Heterospilus was the best represented.
