Eupatorium adenophorum has a serious impact on agriculture and biodiversity in China. Chlorophyll fluorescence parameters of E. adenophorum and its genera were investigated after leaf damage treatments. The results showed that the changes of chlorophyll fluorescence parameters were greatly affected by the treatment methods and species. The changes of chlorophyll fluorescence parameters of E. adenophorum and E. lindleyanum after insect feeding were significantly greater than those after simulated insect feeding. Compared with E. lindleyanum, E. adenophorum had lower LEF, higher Phi2 and PhiNPQ after damage. Therefore, E. adenophorum had a higher defense ability against insect food damage compared with E. lindleyanum.
