Abstract

The present work analyses the diversity of Opiinae (Hymenoptera: Braconidae) in the forest of the Artikutza Estate, within the Natural Park, Penñas de Aya, in the western Pyrenees. Specimens belonging to this subfamily were collected throughout two cycles and in two different habitats: mixed forest and beech forest. A total of 105 specimens, including 20 different species, were collected. Diversity and structure analysis indicated higher diversity for the beech forest habitat, although the community is composed of a few abundant species and many rare species. A relationship between the presence of Opiinae and an increase in temperature was also ascertained. En el presente trabajo se analiza la diversidad de Opiinae (Hymenoptera: Braconidae) en la finca forestal de Artikutza ubicada en el Parque Natural Peñas de Aya y enclavada en el extremo occidental de los Pirineos. Durante dos ciclos se realizó la recolección de esta subfamilia en dos hàbitats diferentes: bosque mixto y bosque de hayedo. En total fueron capturados 105 ejemplares pertenecientes a 20 especies. Posteriormente, mediante los análisis de diversidad y estructura se comprobó que el bosque de hayedo tiene mayor diversidad que el bosque mixto y que esta comunidad está compuesta por poças espécies abundantes y por bastantes raras. También se observo que Ia aparición de Opiinae está relacionada principalmente con el aumento de temperatura.
