Conteúdo: | Survival and development of nymphs, and survival and fecundity of spittlebug adults (Zulia entreriana (Berg.) reared on different grasses were estudied by caging the insects on potted grass plants in screenhouse. Overall, fewer nymphs reached adulthood when reared on Andropogon gayanus cv. CIAT621, Bachiaria decumbens cv. IRI700, Brachiaria brizantha cv. Marandu, Bachiaria decumbens cv. Basilisk. Brachiaria humidicola. Cenchrus ciliaris and P. maximum cv. K187B. Of the 240 nymphs used for P. guenoarum and P.plicatulum, none reached adulthood. Spittlebug adults reared on A. gayanus cv. CIAT621 and P. guenoarum lived shrter and produced about 2/3 as many eggs as those reared on B. decumbens cv. Basilisk. Accourding to Painter's classification of mechanisms of resistance, the  adverse effects on biology of spittlebug were considered to be "antibiosis". This study indicated that the grasses of a great interest to Brazil, particularly A. gayanus cv. CIAT621. b. Brizantha cv. Marandu and P. maximum cv. Coloniao carry good level of antibiosis against spittle bugs; however, P. maximum cv. K187B did not. Because P. guenooarum and P. plicatulum showed high levels of antibiosis, these two grasses should be tested first for adaptability in various regions of Brazil, and if the result is favorable, then under grazing conditions.
