Previous issue date: 2012-01-31 / CAPES / Meloidogyne enterolobii (M. mayaguensis) is nematode specie found in several Brazilian states, parasitizing guavas and other crops. This work aimed to evaluate the reaction of thirty-two plants species to M. enterolobii in the State of Rio de Janeiro. The experiment was conducted in the greenhouse conditions. The population of the M. enterolobiii used in this study was obtained from roots of guava cv. ?Paluma? infested from the municipality of S?o Jo?o da Barra - RJ. The inoculum was multiplied in tomato (Solanum Lycoperyicum) cv. TRural I grown in containers of two liters, with previously autoclaved substrate, which received 5.000 eggs/juveniles/plant. Assessments were made at 90 days after inoculation. Plant roots were processed using Hussey and Barker technique and the population of eggs, juveniles and adults were estimated with the help of Peters counting chamber under an optical microscope. It was determined the final population (Pf) and the reproduction factor (RF), defined as the ratio Pf/Pi, where Pi is the initial population. From the thirty-two plants analyzed, fifteen were susceptible: zucchini (Curcubita moschata Duch), loofah (Luffa cylindrica), white bottlebrush (Callistemon rigidus R. Br), red bottlebrush (Callistemon rigidus R. Br), Brazilian guave (Psidium guineensis), sugarcane var. RB 956911(Saccharum hybrid var. RB 956911), sugarcane var. RB 867515 (Saccharum hybrid var. RB 867515), sugarcane var. RB 92579 (Saccharum hybrid var. RB 92579), sugarcane var. SP 801816 (Saccharum hybrid var. SP 801816), antlerpepper (Capsicum baccatum), hotpepper (Capsicum chinense), tomato cv. TRural I (Solanum lycopersycum cv. TRural I), fis?lia (Physalis angulata), scarlet eggplant (Solanum gilo) and eggplant (Solanum melogena L.). Two were immune: ornamental eucalyptus (Eucalyptus tereticornis) and ox guava (Eugenia stipilata); and fifteen were resistant: count the fruit (Annona squamosa), curly parsley (Petroselinum crispum), pearl pineapple (Ananas cosmosus L. Merril), purple basil (Ocimum pupuraceus), cambuci (Campomanesia phaea), fragrant eucalyptus (Eucalyptus citriodora), eucalyptus (Eucalyptus grandis), pear guava (Psidium acutangulum), yellow guava (Psidium cattleyanum), purple guava (Psidium myrtoides), biribiri (Averrhoa bilimbi L), carambola (Averrhoa carambola L), yellow passionflower (Passiflora maliformis L), rattlepod (crotalaria juncea L) e gray mucuna (Mucuna cin?rea cv. gray mucuna ). / Meloidogyne enterolobii (M. mayaguensis) ? uma esp?cie de nemat?ide encontrado em v?rios estados brasileiros, parasitando goiabeiras e outras plantas cultivadas. Este trabalho teve como objetivo avaliar a hospedabilidade de trinta e duas esp?cies vegetais quanto ? rea??o ao M. enterolobii no Estado do Rio de Janeiro. O experimento foi conduzido em casa de vegeta??o do Instituto de Biologia, no Departamento de Entomologia e Fitopatologia da Universidade Federal Rural do Rio de Janeiro. A popula??o do in?culo inicial do M. enterolobii utilizada foi obtida em campo a partir de ra?zes de goiabeira cv. ?Paluma? infestadas, proveniente do munic?pio de S?o Jo?o da Barra ? RJ. O in?culo foi multiplicado em tomateiro (Solanum Lycopersycum) cv. TRural I cultivadas em vasos de dois litros, com substrato previamente autoclavado, que receberam 5.000 ovos/juvenis/planta. As avalia??es ocorreram aos 90 dias ap?s a inocula??o. As ra?zes das plantas foram processadas utilizando a t?cnica de Hussey e Barker adaptada por Bonnetti e Ferraz (1981) e a popula??o de ovos, juvenis e adultos foram estimada com aux?lio da c?mara de contagem de Peters, sob microsc?pio ?ptico. Os dados obtidos constitu?ram a popula??o final (Pf) e foram utilizados na determina??o do fator de reprodu??o (FR), conforme Collen e D?Herde (1972), definido pela rela??o Pf/Pi, em que Pi ? a popula??o inicial. Das trinta e duas plantas analisadas, quinze foram suscet?veis: abobrinha menina brasileira (Curcubita moschata Duch), bucha (Luffa cylindrica), escova-de-garrafa branca (Callistemon rigidus R. Br), escova-de-garrafa vermelho (Callistemon rigidus R. Br), ara?? (Psidium guineensis), cana-de-a??car var. RB956911 (Saccharum hibrido var. RB956911), cana-de-a??car var. RB 867515 (Saccharum hibrido var. RB 867515), cana-de-a??car var. RB 92579 (Saccharum hibrido var. RB 92579), cana-de-a??car var. SP 801816 (Saccharum hibrido var. SP 801816), pimenta chifre de veado (Capsicum baccatum), pimenta bode (Capsicum chinense), tomate cv. TRural I (Solanum lycopersycum) cv TRural I, f?salis (Physalis angulata), jil? (Solanum gilo) e a berinjela (Solanum melogena L.). Dois foram imunes: eucalipto ornamental (Eucalyptus tereticornis) e o ara?? boi (Eugenia stipilata); e quinze foram resistentes: fruta do conde (Annona squamosa), salsa-crespa (Petroselinum crispum), abacaxi perola (Ananas cosmosus L. Merril), manjeric?o roxo (Ocimum pupuraceus), cambuci (Campomanesia phaea), eucalipto cheiroso (Eucalyptus citriodora), eucalipto (Eucalyptus grandis), ara?? p?ra (Psidium acutangulum), ara??-amarelo (Psidium cattleyanum), ara?? roxo (Psidium myrtoides), biribiri (Averrhoa bilimbi L), carambola (Averrhoa carambola L), maracuj? amarelo (Passiflora maliformis L), crotalaria juncea (crotalaria juncea L) e mucuna cinza (Mucuna cin?rea cv. Mucuna cinza).
