New records and a voucher collection of parasitoid wasps (Hymenoptera) inhabiting agroforestry systems in the colombian amazon basin

Cacao (Theobroma cacao) and copoazú (T. grandiflorum) agroecosystems represent a common source of income or many small-scale farmers in the Colombian Amazon basin. Most of these systems are set in low disturbance environments; they are considered biodiversity-friendly ecosystems inhabited by several groups of insects. In this study, we carried out a preliminary taxonomic inventory of the microhymenopteran parasitoids present in these agroforestry systems. Twenty-six localities of the Amazonian basin of Colombia were sampled using several insect collecting methods (Malaise trap, sweep net, pitfall, and rearing boxes). Collected specimens were curated and cataloged, establishing the first taxonomic voucher collection of parasitoids from the Colombian Amazon basin. We identified 767 specimens representing 64 species, 274 morphospecies, 143 genera and 20 families, 34 genera and 16 species of these being recorded for the first time in the country. The genus Gbelcia is reported for the first time from the Neotropical region. A new parasitoid-host relationship was found for Horismenus cupreus (Eulophidae) attacking larvae of Phyllocnistis sp. (Lepidoptera, Gracillariidae), which feeds on Annona montana (Annonaceae) leaves.
