This study evaluated, under greenhouse conditions, the reaction of the pineapple 'Turiaçu' [Ananas comosus (L.) Merril 'Turiaçu'] to Meloidogyne arenaria, M. enterolobii, M. incognita and M. javanica. Slips were planted in 3-L pots containing autoclaved soil. When the seedlings had developed roots, they were inoculated with 5000 eggs of each nematode species separately. A completely randomized design was adopted with ten replicates. One hundred and fifty days after inoculation, the plants were evaluated for the nematode reproduction factor (Rf = initial population/final population). The pineapple 'Turiaçu' was highly resistant to the four Meloidogyne species, with reproduction factors ranging from 0.00 to 0.03.
