- Observation Field-collected sesame plants grew poorly and had distinct brown root lesions.
- Observation Root-lesion nematodes occurred in four samples, with soil density of 461 ± 211.9 nematodes per kg.
- Observation Root-lesion nematode density in roots was 39 ± 12.3 nematodes per gram.
- Intervention effect Brown lesions appeared on sesame roots eleven weeks after nematode inoculation.
- Observation Final root-lesion nematode numbers averaged 4,316 ± 894.9 in soil and roots.
- Observation Root-lesion nematode reproduction rate was 2.2 ± 0.4.
- Observation Female nematode body length ranged from 533.0 to 645.0 μm, averaging 602.0 μm.

- Observation The population's morphological characters matched descriptions of Pratylenchus coffeae.
- Method / resource Four ITS sequences of 1,248 to 1,254 bp were obtained and deposited in GenBank.
- Method / resource Four 781-bp D2/D3 sequences were obtained and deposited in GenBank.
- Observation ITS sequences showed 99% similarity to P. coffeae GenBank sequences.
- Observation D2/D3 sequences showed 99–100% similarity to P. coffeae sequences; molecular and morphological data confirmed its presence on sesame in Xuchang, the first report in China.
