Hymenopterans parasitoids are an important element of the fauna due to its diversity and biological, ecological and economic importance, especially in the management of agricultural pest. Regarding the cultivation of guaraná (Paullinia cupana var. sorbilis (Mart.) Ducke) knowledge of natural enemies associated natively can be the basis for biological control programs in culture. Thus, the composition of hymenopteran parasitoids associated with two crops of guarana, one of organic management and one of conventional, as well as forested areas adjacent to verify how these areas contribute to provide Hymenoptera for crops mentioned, was studied. A sampling point was determined in the adjacent forest, in the border of the crop and inside of crop, in which have been installed a trap Malaise and four Möerick. The samples were held for four day, fortnightly, from September 2012 to February 2013. A total of 25.951 Hymenoptera parasitoids distributed in 12 superfamilies and 38 families were collected. Of this total, 10.828 parasitoids were collected in conventional management and 15.123 were collected in organic management. In the adjacent forest, Platygastridae was the most abundant family while Encyrtidae in border of culture and crop of culture. Regarding Eulophidae a total of 1.455 individuals were collected, of whom 463 belong to 38 genera were collected in conventional management and 992 (37 genera) were collected in organic management. In conventional management, the adjacent forest had the highest richness and abundance, highlighting the genus Holcopelte. In organic management yielded greater wealth at the border of cultivation and inside of culture within the greater abundance of individuals, being more representative the genus Aprostocetus at all sampling points. In this study it was clear the importance of adjacent vegetation, which is considered a point of refuge and distribution of parasitoids. |
