Abstract

ONODY, Helena Carolina; FRIZO DE MELO, Ivy  and  PENTEADO-DIAS, Angélica Maria. Abundance, richness and diversity of Eiphosoma Cresson 1865 (Hymenoptera, Ichneumonidae) species associated with organic crops. Idesia [online]. 2012, vol.30, n.1, pp. 115-120. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292012000100014.

The aim of this study was to characterize the Eiphosoma Cresson, 1865 (Hymenoptera, Ichneumonidae, Cremastinae) fauna in areas of organic crops production, in relation to abundance, richness and diversity of species. Fourteen Eiphosoma species were identified, two new records to Brazil and three are new species identified. The system with median intensity management showed the highest values of abundance, richness and diversity in relation with higher and lower intensity of management. The climate variables showed less influence on the Eiphosoma fauna than the characteristics (composition and management) of the systems.

Keywords : diversity; integrated pest management; neotropical region; olericulture; parasitoids.
