Griseb. (Amaranthaceae) is an aggressive invader in waterways and pastures throughout most of the southeastern U.S.A., and California. Three insect biological control agents have provided substantial control of aquatic A. philoxeroides in the warmer parts of its range in the U.S.A. However, these insects are less effective against A. philoxeroides in riparian-terrestrial habitats. In this study, the host specificity of Disonycha argentinensis Jacoby, 1991, was investigated to determine its suitability as a biocontrol agent of A. philoxeroides in the U.S.A. No-choice and multiple-choice tests were conducted using 19 test plant species. © 2024 Pacific Coast Entomological Society.
