Zeuzera multistrigata damage in Eucalyptus clones

The infestation level (P%) and the average damage index of Z. multistrigata in different Eucalyptus clones are shown in Table 3. There were significant (P <0.001) differences in the damage among 12 clones. Among the observed clones, clone DH32-29 were the most damaged clone by Z. multistrigata (P% = 28.93%, DI = 1.08). The clone PN14 had 8.42% of the trees were damaged, but all the damaged trees were severely damaged (DI = 3‒4). The clone PNCT3 and PNCTIV were less affected (P% = 7.35‒7.92%; DI = 0.08‒0.10). Among the remaining eight clones, three of them were unharmed and five of them were very moderately damaged (P% <2%) ( Table 3).
