Sugarcane froghoppers in northeast Brazil

Cigarrinhas da cana-de-açúcar no nordeste brasileiro

ABSTRACT:

Froghoppers (Mahanarva spp.) are pests of great economic importance for various regions of Brazil. Many species have a variation in the alar pattern, a parameter that often leads to incorrect identification. We collected froghopper adults in sugarcane fields in the municipalities of Murici and Maceió, in Alagoas, Lagoa de Itaenga and Camutanga, in Pernambuco, São Raimundo das Mangabeiras, in Maranhão, and União and Boa Hora, in the Teresina microregion in Piauí. The froghoppers were assembled and identified and are representatives of three species: M. spectabilis, M. fimbriolata, and M. posticata. This is the first record of M. spectabilis attacking sugarcane fields in the states of Piauí and Maranhão, Brazil. We found the species M. posticata and M. fimbriolata in the sugarcane fields of Alagoas and only M. posticata in Pernambuco.
