Abstract: RESUMOMeloidogyne mayaguensis foi detectado pela primeira vez no estado de Goiás, em duas propriedades (Formosa e Luziânia), causando dano em pomares comerciais de goiaba (Psidium guajava) cv. Paluma de um ano de idade e de 14 anos, respectivamente. Plantas infectadas pelo nematóide mostraram redução de crescimento, clorose generalizada, deficiência nutricional e redução qualitativa e quantitativa de produção. As raízes severamente infestadas apresentaram-se pouco desenvolvidas e deformadas pela presença de mú… Show more

“…All populations of M. enterolobii presented the same phenotypes for esterase (VS1-S1) and malate dehydrogenase (N1a). These phenotypes were reported first for M. enterolobii from China (Esbenshade & Triantaphyllou, 1985) and later for M. mayaguensis from West Africa (Fargette, 1987;Fargette et al, 1996), Martinique (Carneiro et al, 2000), Brazil Siqueira et al, 2009), USA (Brito et al, 2004) and Venezuela (Molinari et al, 2005). This identification was confirmed using two molecular markers which were previously reported to easily separate M. enterolobii from other common RKN species by the size of the PCR products.…”

“…Globally, the results enlarge the range of RKN species that can be unambiguously identified using the SCAR approach, and should allow the implementation of a simple and very sensitive method for the detection of M. enterolobii from field samples, as well as a routine diagnostic test for quarantine purposes. Since M. enterolobii has been spreading rapidly in guava crops in Brazil as a result of the planting of infected seedlings (Carneiro et al, 2007;Siqueira et al, 2009), an easy way to detect this species on guava seedlings (females and egg-masses), in organic manure or soil (J2) would be of vital use in restricting the sale of contaminated seedlings and preventing the spread of this RKN into different areas in the country (Carneiro et al, 2007). Although M. enterolobii has not yet been recognised as a quarantine organism by the Brazilian Ministry of Agriculture (MAPA), it was recently included in the EPPO Alert List in Europe (EPPO, 2008).…”

“…Essa espécie foi relatada pela primeira vez no Brasil nos estados da Bahia e Pernambuco (Carneiro et al 2001) em áreas de goiabeira cultivadas no Vale do São Francisco. Posteriormente foi relatada em todas as regiões brasileiras (Silva et al 2008, Siqueira et al 2009), exceto na região Norte, dessa forma, o presente trabalho fornece subsídios que ampliam a distribuição geográfica desse nematoide no Brasil. Por se tratar de espécie de grande importância econômica pelos prejuízos causados em diversas culturas, medidas preventivas devem ser adotadas no sentido de isolar os focos de infestação e prevenir a disseminação de M. enterolobii para áreas isentas dessa espécie.…”
