Resumo: The root-knot nematode (Meloidogyne spp.) attacks several species causing significant yield losses. Plants of Barbados cherry (Malpighia punicifolia L.) infected by root-knot nematodes exhibit yellowish, reduction in leaf size and dwarfism, and this may even result in death. Taking into consideration the importance of Barbados cherry in Brazil and the lack of research on the influence of these parasites on the crop, this study was carried out with the objective of studying the behaviour of selected genotypes of Barbados cherry infected by M. javanica and M. arenaria, strain 2. Two trials were established following a completely randomized experimental design with six replicates. Plants of M. punicifolia L. propagated by cuttings were inoculated with a suspension containing eggs plus second juvenile stage of M. arenaria, strain 2 (15,000) and M. javanica (17,900). Plants were kept in greenhouse for 90 days. Host capacity of the genotypes was evaluated by gall indexes and mass of eggs for each root system and classified as resistant and susceptible. All genotypes behaved as susceptible to the species of root-knot nematodes tested. KEY-WORDS: Malpighia punicifolia; root-knot nematodes; host plant resistance.

O nematóide das galhas (Meloidogyne spp.) ataca várias culturas causando elevadas perdas de produção. Plantas de acerola infectadas exibem amarelecimento, redução do tamanho das folhas e nanismo, podendo resultar na morte das mesmas. Devido à grande importância da cultura e à escassez de pesquisas sobre a severidade deste parasito em plantas de acerola no Brasil, este trabalho objetivou estudar o comportamento de alguns genótipos de acerola, a Meloidogyne javanica e M. arenaria raça 2. Foram realizados dois ensaios em delineamento inteiramente casualizado com seis repetições. Mudas de acerola produzidas por estaquia foram inoculadas com uma suspensão de ovos + juvenis de 2° estágio de 15.000 e 17.900 de M. arenaria raça 2 e M. javanica, respectivamente, permanecendo 90 dias em casa de vegetação. Após este período, a hospedabilidade dos genótipos foi caracterizada, com base nos índices de galhas e massas de ovos para cada sistema radicular, como resistente e suscetível. Todos os genótipos comportaram-se como suscetíveis às espécies de nematóides de galhas avaliadas.
