Alternanthera philoxeroides (Mart.) Griseb. is an invasive herbaceous amphibious weed species in China. A pyralid moth Herpetogramma basalis (Walker) was discovered feeding on A. philoxeroides through field surveys and may be a potentially useful biocontrol agent. To determine the host range of H. basalis and evaluate its potential to control A. philoxeroides, no-choice and multiple-choice tests were conducted. Herpetogramma basalis fed on target weeds and 29 nontarget plant species. In addition to the target weed A. philoxeroides, H. basalis developed to adult on eight other nontarget species. Herpetogramma basalis survived to adulthood successfully on A. philoxeroides and less successfully on several other Amaranthaceae species. In multiple-choice studies, H. basalis showed a strong oviposition preference for A. philoxeroides over Amaranthus tricolor L. (Centrospermae: Amaranthaceae). Amaranthus tricolor was the only crop plant that supported the complete development of H. basalis. We cautiously recommend H. basalis for the biological control of A. philoxeroides in China.
空心莲子草（Mart.）Griseb. 是中国的一种入侵性草本两栖杂草。通过野外调查发现，一种螟蛾夜蛾 Herpetogramma basalis（Walker）以空心莲子草为食，可能是一种潜在有用的生物防治剂。为了确定 H. basalis 的寄主范围并评估其控制空心莲子草的潜力，进行了非选择性和选择性测试。Herpetogramma basalis 以目标杂草和 29 种非目标植物为食。除了目标杂草空心莲子草外，H. basalis 还在其他八种非目标物种上发育为成虫。H. basalis 在空心莲子草上成功发育为成虫，在其他几种苋科植物上的发育成功率较低。在选择性研究中，H. basalis 对空心莲子草的产卵偏好明显强于苋菜（Centrospermae：苋科）。苋菜是唯一支持 H. basalis 完全发育的作物植物。我们谨慎地推荐 H. basalis 用于控制中国的空心莲子草。
