Ring nematodes (Criconemella xenoplax) are migratory ectoparasites related to pin nematodes, but they are slightly longer and wider. The life cycle takes 25-35 days.   After feeding for several days on roots, females deposit single eggs every two to four days. Optimum conditions for reproduction include a pH near 7 and soil temperatures between 75 and 80 F. Ring nematodes appear to be sensitive to low soil moisture and low pH. Although ring nematodes are found on a wide diversity of crops, few studies have been initiated to determine the potential for yield loss. Ring nematodes often occur in high numbers in peppermint, but no studies have been conducted to determine what damage they cause to mint.
