| Resumo: |
This study aimed to identify natural enemies of the chinch bug, Blissus antillus Leonard, which attacks Tanner grass (Brachiaria arrecta) and Tangola (hybrid of B. arrecta and B. angola), in poorly drained pastureland in the northern region of Rio de Janeiro State. Immature stages of a parasitic mite, identified as Leptus sp. (Parasitengona: Erythraeidae), were commonly found attacking nymphs and adult chinch bugs in all sampled areas of Rio de Janeiro State. An egg parasitoid, Eumicrosoma sp. (Hymenoptera: Scelionidae), was observed on only two occasions attacking eggs which had been collected on plant stems in the field. These natural enemies are possible candidates for biological control programs. Despite extensive sampling, B. antillus was not observed to be infected by entomopathogenic fungi.
