dc.description.abstractThe interaction of the leafhopper-of-roots with the sugar cane is still poorly marked and there is little information on resistant varieties. The phenolic compounds are involved in resistance mechanisms of the antibiosis type, but few studies are devoted to the studying role of these compounds in the interaction of plants with sucking insects. The study was conducted to determine how the sugar cane responded to the infestation of Mahanarva fimbriolata in terms of accumulation of phenolic compounds. An experiment was carried out under controlled conditions in a randomized design in a factorial schedule 3 x 2 x 4, with 3 genotypes and sugar cane, 2 levels of nymphs infestation of M. fimbriolata and sampling 4 times, with 4 repetitions. The genotypes SP80-1816 and RB72454 showed higher levels of total phenols when subjected to an infestation of the pest, but the duration of the nymphal stage and mortality of sharpshooters were significantly lower in those varieties, indicating that the increase in the concentration of phenolic compounds may had been caused by death and decay of the roots. It was not observed variation in levels of total phenols in the variety SP83- 5073 subject to an infestation of M. fimbriolata. However, the mortality of the leafhopperof- roots and duration of the stage of nymphs were significantly higher in genotype, indicating the existence of resistance-type antibiosis. Analysis of correlation showed that higher initial levels of phenolic compounds resulting in mortality of the pest can increase the duration of the nymph stage.en
