| Abstract: | The Growth loss of Eucalyptus caused by Leptocybe invasa Fisher & La Salle were studied. The results showed that the damage of Guanglin nine type was the heaviest, the Huge Leaves type was following. Among the two types, the rate of loss of leaves is the highest, 98.4% and 91.5% in Guanglin nine type, 22.4% and 20.9% in Huge Leaves type. For Guanglin nine type, the average rate of loss of the lateral branches and of host branches is respective 88.1% and 79.8%, the loss of the tree height and diameter is 29.2% and 30.8%. For Huge Leaves type, the loss of the lateral branches and of the host branches is 20.6% and 14.5%, loss of the three height and diameter is 20.5% and 9.1%. |
