| description | The study identified the plant-parasitic nematodes associated with kenaf in selected locations in southwest Nigeria. A survey was conducted in kenaf fields in Ile-Ife and Ikenne, Ibadan and Ilora in September, 2022. The soil sampling procedure involved the collection of samples from 30 distinct locations proximate to the plant roots. Plant-parasitic nematodes (PPNs) were extracted, identified and counted. The frequency of occurrence (FO) and population densities (PD) of the extracted nematodes were calculated. Four genera of PPNs were associated with kenaf in all study locations. These were Meloidogyne, Pratylenchus, Helicotylenchus, and Tylenchus. In Ile-Ife, Meloidogyne had the highest population density per 200 ml soil (72.7%), followed by Helicotylenchus (21.4%), while the lowest density was recorded for Tylenchus (2.0%). In Ikenne, the highest density was recorded for Meloidogyne (47.3%), followed by Pratylenchus (27.9%), and Helicotylenchus (24.4%). The lowest nematode density was recorded for Tylenchus (0.5%). In Ilora, the highest density was recorded for Meloidogyne (66.9%), followed by Helicotylenchus (23.9%), while the lowest density was recorded for Tylenchus (1.4%). The survey in Ibadan showed that nematode with the highest density was Meloidogyne (61.1%), followed by Helicotylenchus (28.0%), while the least density was recorded for Tylenchus (1.3%). This study concluded that four genera of PPN were associated with kenaf in Ikenne, Ile-Ife, Ilora and Ibadan. These were Meloidogyne, Helicotylenchus, Pratylenchus and Tylenchus. The most abundant was Meloidogyne. Therefore, in the management of PPN genera that may impact kenaf production in southwest Nigeria in kenaf, more emphasis should be placed on root-knot nematodes. |

Se realizó un muestreo en campos de kenaf en Ile-Ife e Ikenne, Ibadan e Ilora en septiembre de 2022. El procedimiento de muestreo de suelo consistió en la recolección de muestras en 30 puntos distintos cercanos a las raíces de las plantas. Se extrajeron, identificaron y contabilizaron los nematodos fitoparásitos (NFP). Se calcularon la frecuencia de ocurrencia (FO) y las densidades de población (DP) de los nematodos extraídos. Cuatro géneros de NFP se encontraron asociados al kenaf en todas las localidades del estudio: Meloidogyne, Pratylenchus, Helicotylenchus y Tylenchus. En Ile-Ife, Meloidogyne presentó la mayor densidad de población por cada 200 ml de suelo (72,7%), seguido por Helicotylenchus (21,4%), mientras que la densidad más baja se registró para Tylenchus (2,0%). En Ikenne, la mayor densidad fue para Meloidogyne (47,3%), seguido de Pratylenchus (27,9%) y Helicotylenchus (24,4%). La densidad más baja de nematodos se registró para Tylenchus (0,5%). En Ilora, la densidad más alta correspondió a Meloidogyne (66,9%), seguida de Helicotylenchus (23,9%), con la menor densidad para Tylenchus (1,4%). El muestreo en Ibadan mostró que el nematodo con mayor densidad fue Meloidogyne (61,1%), seguido de Helicotylenchus (28,0%), mientras que la menor densidad fue para Tylenchus (1,3%). Este estudio concluyó que cuatro géneros de NFP están asociados al kenaf en Ikenne, Ile-Ife, Ilora e Ibadan. Estos fueron Meloidogyne, Helicotylenchus, Pratylenchus y Tylenchus. El más abundante fue Meloidogyne. Por lo tanto, en el manejo de los géneros de NFP que pueden afectar la producción de kenaf en el suroeste de Nigeria, se debe poner mayor énfasis en los nematodos del nódulo radical (Meloidogyne).O estudo identificou os nematoides fitoparasitas associados ao kenaf em localidades selecionadas no sudoeste da Nigéria. Um levantamento foi realizado em campos de kenaf em Ile-Ife e Ikenne, Ibadan e Ilora em setembro de 2022. O procedimento de amostragem de solo envolveu a coleta de amostras em 30 locais distintos próximos às raízes das plantas. Os nematoides fitoparasitas (NFPs) foram extraídos, identificados e contados. A frequência de ocorrência (FO) e as densidades populacionais (DP) dos nematoides extraídos foram calculadas. Quatro gêneros de NFPs foram associados ao kenaf em todos os locais de estudo. Estes foram Meloidogyne, Pratylenchus, Helicotylenchus e Tylenchus. Em Ile-Ife, Meloidogyne apresentou a maior densidade populacional por 200 ml de solo (72,7%), seguido por Helicotylenchus (21,4%), enquanto a menor densidade foi registrada para Tylenchus (2,0%). Em Ikenne, a maior densidade foi registrada para Meloidogyne (47,3%), seguido por Pratylenchus (27,9%) e Helicotylenchus (24,4%). A menor densidade de nematoides foi registrada para Tylenchus (0,5%). Em Ilora, a maior densidade foi de Meloidogyne (66,9%), seguida por Helicotylenchus (23,9%), enquanto a menor densidade foi de Tylenchus (1,4%). O levantamento em Ibadan mostrou que o nematoide com a maior densidade foi Meloidogyne (61,1%), seguido por Helicotylenchus (28,0%), enquanto a menor densidade foi registrada para Tylenchus (1,3%). Este estudo concluiu que quatro gêneros de NFPs estavam associados ao kenaf em Ikenne, Ile-Ife, Ilora e Ibadan. Estes foram Meloidogyne, Helicotylenchus, Pratylenchus e Tylenchus. O mais abundante foi o Meloidogyne. Portanto, no manejo de gêneros de NFPs que podem impactar a produção de kenaf no sudoeste da Nigéria, deve-se dar maior ênfase aos nematoides de galhas (Meloidogyne).Facultad de Agronomía, Universidad de la República - INIAAdesuyi Ayoola, Obafemi Awolowo University, Institute of Agricultural Research and Training, Moor Plantation, Ibadan, Nigeria https://orcid.org/0000-0001-9111-9274Daramola Fisayo, Scotland's Rural College (SRUC), Department of Crop and Soil Sciences, Edinburgh, Scotland, UK https://orcid.org/0000-0003-2235-4734Ezaka Emmanuel, Obafemi Awolowo University, Institute of Agricultural Research and Training, Moor Plantation, Ibadan, Nigeria https://orcid.org/0000-0002-4338-7650Adekunle Ojo, Obafemi Awolowo University, Department of Crop Production and Protection, Ile-Ife, Osun State, Nigeria https://orcid.org/0000-0003-0243-16912026-03-18T17:57:16Z2026-03-18T17:57:16Z2026Artículoinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersione1823application/pdfAdesuyi, A., Daramola, F., Ezaka, E. y otros.
