Description
Survival and development of nymphs, and survival and fecundity of spittlebug adults [Zulia entreriana (Berg.)] reared on different grasses were studied by caging the insects on potted grass plants in screenhouse. Overall, fewer nymphs reached adulthood when reared on Andropogon gayanus cv. CIAT621, Brachiaria decumbens cv. IRI700, Brachiaria brizantha cv. Marandu, Brachiaria mutica, Chloris gayana, Panicum maximum cv. Coloniiio, Paspalum guenoarum and Paspalum plicatulum than on Brachiaria 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 shorter and produced about 2/3 as many eggs as those reared on B. decumbens cv. Basilisk. According to Painter's classification of mechanisms of resistance, the adverse effects on biology of spittlebugs 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. Coloniiio carry good level of antibiosis against spittle bugs; however, P. maximum cv. K187B did not. Because P. guenoarum 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.
