Abstract Aim An increasing number of exotic plants and their biological control agents are being introduced into new regions. Therefore, it is necessary to study interactions manage the future directions plant invasions under different scenarios temperature rise. Location China. Method We investigated distribution patterns two most prevalent invasive aquatic in world, Alternanthera philoxeroides Eichhornia crassipes , at a large scale studied both with respective agents, Agasicles hygrophila Neochetina eichhorniae response Results Both performed better warmer climates common garden experiments. However, populations A. occurred only temperate zone because this species experienced competitive exclusion from E. suppression due herbivory tropical subtropical areas. Moreover, zones, where co‐occur, zone, occurs present, competition hindered performance . extreme high‐temperature environment, improved, while worsened. In addition, combination N. also reduced but still dominated when Main conclusions Our results indicate that climate warming introduction herbivores do not alter interspecific relationship between our suggests warming, will replace as dominant some communities warm though extremely events slow replacement process.
