Abstract:In the invaded areas, it is believed that invasive species reduce their investment in defense due to the absence of natural enemies. This study explored the defense strategies of invasive plants through research on the invasive species. Field investigation indicated that invasive plants have a driving effect on herbivorous pests, and the frequency of leaf damages of native plant reaches a peak at 2–3 m distance from the invasive species. A feeding preference assay with two generalist herbivorous insects (nativ… Show more
