E. camaldulensis seems to be moreattacked than the other Eucalyptus species<strong>and</strong> heavy infestations, reaching 100% <strong>of</strong>attacked seedlings, were reported mainlyin young plantations <strong>and</strong> nurseryseedlings <strong>of</strong> this species. Currently, nocontrol measures are available againstboth species, even if the parasitingactivity <strong>of</strong> Closterocerus chamaeleonseems to effectively reduce the infestationlevels <strong>of</strong> O. <strong>maskelli</strong> (7, 25). However,more precautions would be needed whenexchanging eucalyptus plants forplanting, enhancing the level <strong>of</strong>monitoring <strong>and</strong> carrying out research inarboretums to identify Eucalyptus specieswhich resist to this gall wasp.__________________________________________________________________________RESUMEDhahri S., Ben Jamaa M.L. et Lo Verde G. 2010.
