Abstract Background Interactions between alien plants and insect herbivores in introduced ranges may determine their invasion success. However, few studies have investigated whether respond differently to native genotypes of matter. We conducted a greenhouse experiment examine the effects herbivory by ( Spodoptera litura ), an S. frugiperda simultaneously both species on growth, morphology, biomass allocation 17 invasive clonal plant Hydrocotyle verticillata , used selection gradient analysis test which conditions favor specific leaf or root trait value. Results Different H. showed significant variation allocation, but responses were relatively consistent. All three treatments significantly decreased total mass stolon mass, increased area. Herbivory simultaneous also petiole ramet mass. Selection that traits varied under different treatments. To achieve greater fitness, as measured and/or number ramets, favored larger area lower area, root-to-shoot ratio herbivory. Conclusions demonstrated contrasting insects, showing remarkable ability coordinate plasticity optimize allocation. This strategy allows fitness various conditions, potentially contributing its These findings highlight importance plant–herbivore interactions shaping dynamics underscore complex adaptive mechanism enables establish spread ranges.
