 The third biological control agent to target Neoscapteriscus in Florida was the South American nematode Steinernema scapterisci . Small @-@ scale releases proved it could persist for years in mole @-@ cricket @-@ infested sandy Florida soils . Its use as a <unk> against Neoscapteriscus was patented , making it attractive to industry . Industrial @-@ scale production on artificial diet allowed large @-@ scale trial applications in pastures and on golf courses , which succeeded in establishing populations in several counties , and these populations spread , but sales were disappointing , and the product was withdrawn from the market in 2014 .
