Reported median body size for this species (Length mm; width micrometers; weight micrograms) - Click:
West Africa, Senegal on peanut and soybean (Germani, 1981). Frequently found in Florida associated with Sansevieria trifasciata and other Sansevieria species (van den Berg et al , 2016).
Damage to important economic crops including peanut and soybean (Germani, 1981).
Ectoparasite and migratory endoparasite in root cortex.
All stages of the nematode are infective.
Peanut, soybean. Also, banana, corn, mango, tomato.
Ecophysiological Parameters:
In pot experiments, S. cavenessi reduced growth of both soybean and peanuts. Soybean appearesd to be less tolerant than peanut. Besides reducing yield, the nematode may damage legumes and nitrogen-fixing ability (Germani, 1981).
