Abstract

Hymenopteran parasitoids strongly associated with the sugarcane borer [Diatraea saccharalis (Lepidoptera: Crambidae)] may be found both in organic and conventional sugarcane farming systems. This study aimed to sample parasitoids associated with sugarcane borer in organic, organic near a forest fragment and conventional systems. Two colors of Moericke traps were used (yellow and white) to collect insect samples, and faunistic analyses were performed to determine the composition of parasitoids in each management type. A total of 287 insects were collected, with the most abundant families being Diapriidae (44.44 %), Eulophidae (37.5 %) and Braconidae (18.06 %). The most abundant genus in the organic system was Omphale (Eulophidae), Omphale (Eulophidae) in the organic system near the forest fragment, and Omopria and Coptera (Diapriidae) in the conventional system. The parasitoids were more abundant in the organic system (43.06 %), followed by the organic system near the forest fragment (36.81 %) and the conventional system (20.14 %). The yellow trap was the most effective in attracting parasitoids, which were generally more abundant in organic systems, regardless of proximity to forest fragments.
