Risk assessment of non-target effects of Closterocerus chamaeleon (Girault) parasitoid of the eucalypt gall maker Ophelimus maskelli (Ashmead) (Hymen…
2015
The pre-release risk assessment, a recommended practice in biological control programmes, was carried out before introducing Closterocerus chamaeleon (Girault), a eulophid parasitoid of the eucalypt gall maker Ophelimus maskelli (Ashmead) (Hymenoptera, Eulophidae), in Sicily, Italy. We evaluated its host specificity in laboratory small arena no-choice tests on six non-target hosts, using O. maskelli as a control species. The non-target species fit with at least one of the following criteria: a) common geographical origin; b) ecological or behavioural affinities with the target host; c) concealed habit of the preimaginal stages; d) taxonomic affinity; e) taxonomic affinity with hosts of cong…
First Record of Leptocybe invasa and Ophelimus maskelli Eucalyptus Gall Wasps in Tunisia
2010
Two Australian gall wasps were detected for the first time in Tunisia on the foliage of Eucalyptus camaldulensis trees. Leptocybe invasa was detected in 2004, while Ophelimus maskelli in 2006. L. invasa makes galls on petioles, leaf midribs and young branches whereas O. maskelli induces galls on limbs. Vigilance is recommended when seedlings are carried to plantation.
