The most common species within this genus, with a world-wide distribution, is A. agricola (de Man, 1884) Andrássy, 1954. It was originally described from the Netherlands as Tylenchus agricola by Dr. JG de Man in 1884. It has a short body with fine cuticle annulation and a very long filiform tail with a pointed tip. The amphidial aperature can be found on the labial plate. The stylet is short with well developed knobs. Aglenchus agricola can be found in terrestrial but also in semi-aquatic and aquatic habitats. It is common in grasslands but has also been found on mosses. It is a migratory ectopararsite on roots of grasses and several dicotyledonous plants.
