Integrated Pest Management (IPM) is a long-term, low toxicity and sustainable way of controlling
pests in agricultural systems. However, success of an IPM plan extremely depends on
identification of pest species, which allows distinguishing whether or not the insect species are
dangerous to agricultural crops. Crops of banana, subgroup Prata, located in the Project Jaíba near
to the São Francisco River (northern of Minas Gerais State) (Koppen Climatic Classification
AW), presented large defoliation by a phytophagous insect in the last years. Banana growers
attributed the attack to a grasshopper species. The objective this study was to identify the insect
and confirm in laboratory the pest status for future IPM programs. Grasshopers were collected in
different banana crops located in the São Francisco River and Rio das Velhas River in Minas
Gerais State. Specimens were reared in laboratory feeding on banana leaves and fruits aiming to
reproduce the defoliation and damages registered in the field. Insect specimens were prepared for
identification and preserved in the Banana Pest Collection of the Itajaí Experimental Station ?
EPAGRI. The species was identified as Tropidacris collaris (Stoll, 1813) (Orthoptera,
Romaleidae), a grasshopper usually reported exceeding 100mm in length. In laboratory, the adults
collected in the banana crops fed on banana leaves completing the reproductive cycle and laying
eggs, which denotes the potential threaten for banana crops. On the other hand, no damage was
registered in fruits, denoting a clear preference for leaves. Therefore, T. collaris arises as a
potential pest for banana crops in Brazil, demanding studies in field for management and control.
