| Abstract: | The results of studies on control threshold showed that ranges of <50%, 51 ?75% and >75% of defoliating rate were light, middle and heavy damage, respectively, The control threshold of Pantana phyllostachysae Chao was based on the relationship between the amount of defoliating and the loss of Moso bamboo yield. |
