- Preference of the parasitoid Cotesia flavipes (Cam.) (Hymenoptera: Braconidae) for Diatraea (Lepidoptera: Crambidae) Cinthia Conceição Matias da Silva Edmilson Jacinto Marques José Vargas Oliveira Ellen Carine Neves Valente Agrociencias behavior parasitism sugarcane borer The sugarcane borer Diatraea flavipennella (Box.) (Lepidoptera: Crambidae), has ultimately predominated in the sugarcane fields of the Brazilian northeast region, despite the continual release of the parasitoid Cotesia flavipes (Cam.) (Hymenoptera: Braconidae). Questions have been raised about the efficiency of Diatraea spp. in controlling D. flavipennella. In this study, females reared in one of the borers were tested individually and as hosts with the larvae of either of the Diatraea species alone or the larvae of both species. In the first experiment, the females were released for 10 min within the experimental arena using only olfactory cues. In the second experiment, C. flavipes females were individually released for 30 min. within the arena, allowing direct contact with its host, either D. saccharalis or D. flavipennella, or both host species at the same time. The wasps showed no preference for either one of the hosts, thus being able to locate borers in general. 2012 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303026475003 10.4025/actasciagron.v34i1.11720 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
