This study aimed to characterize the resistance of 31 passion fruit (Passiflora sp.) genotypes to Fusarium oxysporum f. sp. passiflorae (FOP). About 20 seedlings of each genotype were inoculated by immersing the roots in a suspension of 10(6) macroconidia mL-1 for five minutes and then transplanting them into pots containing a mixture of soil and sterile substrate. They were evaluated daily for 120 days for the occurrence of wilt symptoms and death. These data were used to calculate the area under the disease progress curve, for survival analysis and grouping. The mortality rate ranged from 0 to 100% and the AUDPC ranged from 0 for genotypes without symptoms of the disease to 6,650.63 for the hybrid HFOP-01. Genotypes were classified into four subgroups: resistant, moderately resistant, susceptible and highly susceptible. The resistance was genotype dependent, but no significant variation was found between the purple and the yellow P. edulis.

O propósito deste trabalho foi estudar a flutuação populacional de cigarrinhas em pormar cítrico em formação. A população de cigarrinhas foi monitorada usando-se armadilhas amarelas. A espécie mais abundante foi Bucephalogonia xanthophis (Berg). Baixas populações de Acrogonia sp., Dilobopterus costalimai Young e Oncometopia facialis (Signoret) foram detectadas durante o experimento.

The purpose of this research was to study the population fluctuation of sharpshooters in young citrus groves. The sharpshooters population was monitored using yellow stick traps. The most abundant species was Bucephalogonia xanthophis (Berg). Low populations of Acrogonia sp., Dilobopterus costalimai Young and Oncometopia facialis (Signoret) were detected throughout the trial.
