This species is included for comparison to other species that are considered invasive. Biological Control Although seed predators from native range countries constitute potential biological control agents, Carter (1998) reports that benefits are liable to be limited by stock management practices, since seeds may be eaten and redistributed by grazing animals before insects such as the bruchid beetles Caryedon serratus and Bruchidus sahlbergi gain access.
