Conteúdo: 	The beef cattle industry in tropical America, with its extensive production systems, depends on forage grasses for meat production. Several species of the genus Brachiaria comprise the most important of these grasses. Because of their excellent adaptation, particularly of B. decumbens to low-fertility acid soils, they have been widely adopted throughout Central and South America. The extensive monoculture of B. decumbens, however, has favored the buildup of several spittlebug species, the most damaging pests of Brachiaria in tropical America. These insects can drastically reduce plant growth, dry matter production as well as forage quality (Valério et al., 2001). A great effort has been devoted to finding grasses resistant to spittlebugs. The objective of the present work was to evaluate 28 hybrids of the genus Brachiaria, from the germplasm available at Embrapa Beef Cattle Research Center, for resistance to the spittlebug Notozulia entreriana using the selection criteria of nymphal survival and nymphal period.
