Comunidade de parasitóides associada à cultura do café em Piatã, Chapada Diamantina, BA

Abstract

Parasitoid community associated with coffee crop in Piatã, Chapada Diamantina, BrazilHymenopteran parasitoids are natural enemies of insect pests and have demonstrated efficiency in strategies of biological control, contributing for the maintenance of the ecological balance in agroecosystems. The aim of this research was to identify the diversity of parasitoid wasps in coffee crops in Piatã, BA, Brazil. Malaise traps were installed in the plots and remained in the field for seven days in monthly samplings from September 2006 to August 2007. A total of 14.699 individuals were collected. The parasitoids were distributed through 9 superfamilies: Ceraphronoidea, Chalcidoidea, Chrysidoidea, Cynipoidea, Evanioidea, Ichneumonoidea, Mymarommatoidea, Platygastroidea, Proctotrupoidea and 29 families. Twenty two constant and 11 dominant families, standing out the families Ichneumonidae, Braconidae e Scelionidae as the most frequent. Families Braconidae, Eulophidae and Bethylidae indicated as promising biological control programs in coffee were collected throughout the phenological cycle of the crop.
