Abstract Above–belowground insect herbivore interactions and plant compensatory growth are crucial for reshaping the fitness of invasive plants, it is likely that climate warming, nitrogen (N) deposition, provenance influence this interaction in a complex way. We performed an experiment with Solidago canadensis from home introduced ranges, leaf‐chewing Spodoptera litura , root‐feeding Protaetia brevitarsis under warming N addressed how these abiotic stressors jointly shaped reciprocal effects between S. P. after herbivory. Under ambient conditions, inhibited each other on basis growth; addition or plus shifted even reversed competition depending provenance. While survival‐based above–belowground differed growth‐based ones, also neutralism amensalism detected conditions its range was more tolerant herbivory than conditions; decreased native but increased relative to conditions. These findings suggest deposition could enhance positive interactions, increasing pressures might be important mediating change host invasions.
