Eggplant is a crop of great development and opportunity for economic growth worldwide, it can be compromised by pests and phytopathogenic diseases that affect the yield in the production of the crop. The objective of the research was the identification of nematodes associated with the eggplant crop, the sampling was carried out in the state of Aguascalientes in the community of Cañada Honda (latitude 22 002254, north latitude 22° 0’8 11584”, west longitude -102 192580, 102° 11’ 33 2862”) in 2019, the technique used to extract filiform nematodes was that of sieving and centrifugal fluctuation with sucrose solution. The keys to the identification of nematodes were those proposed by Cid del Prado (2009), the keys of Esienbcach (1985); Nickle (1991); Hunt (2009), for the root samples, the dissection of the galls was performed to obtain the possible nematodes existing in the root, in the same way, a visual analysis of each root was carried out and the damage caused by galls was classified. The average of nematodes in each soil sample analyzed was 85 nematodes in 100 g of soil, the root damage index showed a value of 5 to 6 according to Bridge and Page’s scale. Four genera were identified: Nacobbus spp., Rhabditis spp., Psilechus spp., and Dorylaimus spp.
