Abstract: Herbivory pattern on leaves is a useful way to evaluate insect species and prevent insect pest. It was investigated the herbivory patterns and intensity on the leaves of 17 evergreen plant species in subtropical evergreen broad-leaved forests which grown on about 450 meters and 1 200 meters Mt. Meihuashan, Fujian Province. The results were as follows:(1) A total of 15 herbivory patterns were found, and for each tree species, the herbivory patterns ranged from 8 to 14. The frequency of each herbivory pattern on leaves of 17 plant species varied from 0.5% to 28.7%. The highest frequency was Edge Defoliation (ED) (37.01%), while that of Middle Vein Defoliation (MVD) was the lowest (0.02%). (2) The herbivory intensity on the leaves of Schima superba was the highest (9.60%), that of Castanopsis fargesii was next (6.61%), and while that of Camellia Oleifera was the lowest (0.34%). (3) Correlation analysis showed that there were significant positive correlations in six pairs of herbivory patterns and significant negative correlations in two pairs. (4) The investigation of four plant species, Castanopsis eyrei, Schima superba, Castanopsis fargesii, Camellia fraternal, growing separately in 1 200 meters and 450 meters mountain, showed that the herbivory intensity on leaves of the four plant species in 1200 meters elevation was higher than that in 450 meters elevation. And the greatest range of herbivory intensity in four plant species was Schima superba, from 13.81% to 2.93%.
