Abstract

The entomopathogenic nematode, Steinernema scapterisci (Rhabditida: Steinernematidae), was originally isolated from the mole cricket Scapteriscus vicinus (Orthoptera: Gryllotalpidae) in Uruguay. Subsequently, a population of S. scapterisci was isolated from the mole cricket S. borellii in Colon, Buenos Aires, Argentina. Because of the distance between the nematode isolates from Uruguay and Argentina and the different Scapteriscus species from which they were isolated, a study to examine the possible heterogeneity of S. scapterisci populations over space was conducted. Morphological variation was correlated with random amplified polymorphic DNA markers.
