Quarantine surveillance is essential to prevent invasive pests during germplasm exchange. During inspection of imported groundnut (Arachis hypogaea L.) seeds at ICAR-National Bureau of Plant Genetic Resources, Regional Station Hyderabad, plant parasitic nematode Ditylenchus spp. were detected. Their morphological characteristics closely resembled Ditylenchus africanus. Although species-level confirmation was not established due to morphological similarities with related taxa. The D. africanus was considered the most likely identity as only Aphelenchoides arachidis and D. africanus are known to be seed-transmitted in groundnut, supporting the latter as the likely identity. Its seed survival and rapid reproduction pose a serious risk. As D. africanus is absent in India, the consignment was rejected and incinerated, highlighting the importance of strict quarantine measures.
