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.

Se presenta un listado de 300 morfoespecies, de las cuales se determinaron 83 especies y 146 géneros de Braconidae en el estado de Oaxaca.

Para la selva mediana subperennifolia, se registró el mayor número de géneros (81), entre los más representativos se encontraron Heterospilus, Opius y Bracon. En zonas con temperaturas cálidas se registró el 85 % de los géneros, incluyendo representantes de las subfamilias Alysiinae, Euphorinae, Doryctinae y Microgastrinae. El clima con mayor presencia de bracónidos fue el cálido subhúmedo y las subfamilias más abundantes fueron Doryctinae y Microgastrinae. En el clima semicálido subhúmedo se encontraron especialmente especímenes de Agathidinae. Los parasitoides se distribuyeron desde los 20 a 2900 msnm, pero el mayor número de registros se encontró a una altitud de 736 m y el género Heterospilus fue el mejor representado.

Braconidae é uma família altamente diversificada dentro da ordem Hymenoptera, possuindo grande importância no controle biológico tanto em sistemas agrícolas como em sistemas naturais. Contudo, a diversidade do grupo ainda é pouco conhecida para a região amazônica. Neste sentido, o presente estudo vem contribuir para este conhecimento através do inventariamento da assembléia de braconídeos do Parque Natural Municipal de Porto Velho, Rondônia. As coletas foram realizadas pelo período de um ano, utilizando seis armadilhas Malaise em uma área de Floresta Ombrófila Aberta com palmeiras. Foram coletados 377 espécimes, identificados em 17 subfamílias e 56 gêneros. As subfamílias Braconinae, Microgastrinae, Doryctinae e Rogadinae foram consideradas muito abundantes, assim como os gêneros: Aleiodes, Bracon, Capitonius, Compsobracon, Heterospilus, Hymenochaonia, Opius, Pedinotus, Rogas e Stantonia. O índice de diversidade calculado para as subfamílias (H = 2,15) e gêneros (H = 3,3) coletados neste trabalho foi maior do que o encontrado em alguns trabalhos em outras regiões do Brasil. A abundância desses insetos durante a estação chuvosa foi significativamente maior do que na seca. Este trabalho contribui com novos dados faunísticos sobre Braconidae para o Estado de Rondônia.

Braconidae is a highly diversified family of Hymenoptera and usually known by their role in biological control both in agricultural and natural ecosystems. Despite of that, little is known about its diversity in the Amazon region. The present work inventoried the braconid fauna of an Open Ombrophylous Forest with Palm Trees of the Parque Natural Municipal de Porto Velho, RO. Insects were collect from June/2008 to May/2009 using six Malaise traps in different parts of the reserve. A total of 377 wasps were captured, 17 subfamilies and 56 genera identified. Braconinae, Microgastrinae, Doryctinae and Rogadinae subfamilies were very abundant, and also the genera Aleiodes, Bracon, Capitonius, Compsobracon, Heterospilus, Hymenochaonia, Opius, Pedinotus, Rogas and Stantonia. The calculated Shannon diversity index was 2.15 and 3.3 for subfamily and genera, respectively, which were, generally, higher than the values found for other regions in Brazil. Generally, parasitoids were more abundant during the rainy season. The present work contributes with new genera records and faunistic data of Braconidae in Rondonia State, western Amazon.

La mayoría de los miembros de la familia Braconidae son parasitoides que actúan como reguladores naturales de otros insectos. Los principales reportes provienen de zonas montañosas. Sin embargo, poco se conoce de estos insectos en zonas áridas y semiáridas o en ambientes secos de Venezuela. Este trabajo se realizó en dos ecosistemas naturales del estado Lara (Parques Nacionales Cerro Saroche, PNCS, y Terepaima, PNT) con el propósito de conocer en forma preliminar la composición biológica de esta familia en este tipo de ambientes. Para el muestreo se utilizaron bandejas amarillas ubicadas en dos estratos altitudinales de cada localidad. Se identificaron 13 subfamilias de Braconidae: Alysiinae, Blacinae, Doryctinae, Cenocoelinae, Cheloninae, Euphorinae, Helconinae, Hormiinae, Meteorinae, Microgastrinae, Opiinae, Orgilinae y Rogadinae. Igualmente, se identificaron 20 géneros distribuídos en las cuatro principales subfamilias muestreadas (Doryctinae, Alysiinae, Cheloninae y Rogadinae). En ambos parques predominó la subfamilia Doryctinae, seguida por Alysiinae en el PNT y por Cheloninae en el PNCS. El mayor número de ejemplares se colectó a 1200 msnm en ambos parques, y el PNT fue el que reportó el mayor número de individuos.

The vast majority of members of the family Braconidae are parasitoids that act as natural regulators of other insects. Most of the reports come from mountain areas. However, little is known of these insects in arid and semi-arid areas, or dry environments, of Venezuela. This study was carried out in two natural ecosystems of Lara State (National Parks Cerro Saroche, PNCS, and Terepaima, PNT) in order to appreciate the biological composition of this family in those environments. For sampling, yellow traps were placed at two elevation points within each locality. We identified 13 subfamilies of Braconidae: Alysiinae, Blacinae, Doryctinae, Cenocoelinae, Cheloninae, Euphorinae, Helconinae, Hormiinae, Meteorinae, Microgastrinae, Opiinae, Orgilinae and Rogadinae. Likewise 20 genera were identified within the main four subfamilies (Doryctinae, Alysiinae, Cheloninae, and Rogadinae). In both parks the subfamily Doryctinae was the most important, followed by Alysiinae in PNT and Cheloninae in PNCS. The largest number of specimens occurred at 1200 meters elevation in both locations, and PNT was the park with the highest number of individuals.

The doryctine wasp genus Hecabolus Curtis and its type species, H. sulcatus Curtis, are redescribed. A new species from Mexico, H. mexicanus sp. nov., is described and illustrated. The new species is distinguished from H. sulcatus and the other known species of the genus, H. costaricensis Marsh, in having a narrower pterostigma, longer discoidal (discal) cell, basal (1M) and recurrent (m-cu) veins diverging posteriorly, first abscissa of mediocubital (M+CU) vein of hind wing as long as the second abscissa (1M), and first metasomal tergite with a very small dorsope. A key for identification of the 3 known species of Hecabolus is provided.

The material studied comes from three of the several natural environments which still occur in Paraná State. The samples were collected during the project PROFAUPAR, developed by Departamento de Zoologia, Universidade Federal do Paraná. The selected sites were: Antonina (in the coastal plain), São José dos Pinhais (in the coastal mountain range) and Telêmaco Borba (in the second plateau). During one year of the project, 2,106 specimens of Braconidae were collected with light trap. These wasps represented 21 subfamilies and 1,966 specimens were identified in 85 genera. Hormiinae, Rogadinae, Microgastrinae, Alysiinae, Doryctinae and Meteorinae were the most frequent subfamilies. Indices of diversity and evenness were used to discuss richness and dominance of genera in each locality. Statistical analyses indicated that the asymptote of actual genera richness have been approached only to Antonina and Telêmaco Borba.

We made a checklist of braconids of the Colección Entomológica del Instituto de Fitosanidad del Colegio de Postgraduados (CEIFIT). A list of 92 genera in 40 tribes and 20 subfamilies of braconids was obtained. From these genera, Schoenlandella is a new report from Mexico. The most abundant genera were Aphidius, Opius, Apanteles, Diaeretiella and Aleiodes. The most representative (because its high number of species) genera were Opius, Bracon and Apanteles. The most representative subfamilies were Alysiinae and Doryctinae in the colección del CEIFIT. Species from the genera Aphidius, Diaeretiella, Lysiphlebus, Praon, Trioxys, Habrobracon, Chelonus, Cotesia and Diachasmimorpha, were found to be parasitic on different pest species of economic importance.
