Short duration, high intensity grazing was evaluated as a method of reducing spittiebug numbers in central Brazil. Intense grazing pressure during the nymphal period resulted in a temporary reduction in nymphal density but aciditiorrai hatching of eggs allowed the density to increase. Intense grazing during the, last generation of adults, prior to the start of the dry season drastically reduced the, nymphal population. Grazing by cattle in general provided an unsuitable habitat for spittiebug egg survival as both grass height and plant cover decreased under ali grazing trealments. In freavily infested pastures (> 20 nymphs/m2) it is recorrurrended to graze the grass short: (< 10 em) during the last gencration of adults (April-July) in order to discourage oviposition by adults laying diapause eggs and to expose eggs to detrimental conditions during the dry season. In pastures with low spittlebug density (< 20 nymphs/m 2 ) it is recommended to maintain the forage height at 15 em - 20 em during the rainy season for maximum production and efficient use of the forage resource.
