Influence of Corymbia hybridisation on crown damage by three arthropod herbivores

Nahrung H. F., . and Waugh R., . and Hayes R. A., . and Lee D. J., . Influence of Corymbia hybridisation on crown damage by three arthropod herbivores. pp. 383-388. ISSN 0128-1283

Three common pests (eucalypt tortoise beetle Paropsis atomaria leaf blister sawfly Phylacteophaga froggatti and eriophyid mites) of commercial spotted gum plantations were assessed for their crown damage levels on parent and hybrid Corymbia taxa (Corymbia torelliana C. citriodora subsp. variegata and their hybrid) at three common-garden field sites. Damage levels differed significantly between sites for all three herbivore species and between taxa for eriophyid mites and P. atomaria. However herbivore response to hybridisation only differed for P. atomaria between sites even where damage levels did not. Hybrids exhibited three common patterns of susceptibility relative to parent taxa being most commonly intermediate to their parents for crown damage (additive resistance pattern) or no difference between parents and hybrids or with one incidence of dominance for susceptibility.

Abstract

Three common pests (eucalypt tortoise beetle Paropsis atomaria leaf blister sawfly Phylacteophaga froggatti and eriophyid mites) of commercial spotted gum plantations were assessed for their crown damage levels on parent and hybrid Corymbia taxa (Corymbia torelliana C. citriodora subsp. variegata and their hybrid) at three common-garden field sites. Damage levels differed significantly between sites for all three herbivore species and between taxa for eriophyid mites and P. atomaria. However herbivore response to hybridisation only differed for P. atomaria between sites even where damage levels did not. Hybrids exhibited three common patterns of susceptibility relative to parent taxa being most commonly intermediate to their parents for crown damage (additive resistance pattern) or no difference between parents and hybrids or with one incidence of dominance for susceptibility.
