Host Specificity Testing

Additional retrospective testing of the gum leaf skeletoniser (Uraba lugens) biological control agent Cotesia urabae was conducted against the endemic moth Celama parvitis Although this native was included in host specificity testing before EPA approved the parasitoids release this work aimed to increase the sample size to better assess the potential risk posed The effect that different periods of host deprivation and prior oviposition experience had on the parasitoids readiness to attack was examined in a sequence of nochoice tests No parasitoids emerged from the 52 of larvae that survived to pupation thus confirming C parvitis as a nonhost Dissections of larvae that died during laboratory rearing revealed that 63 had contained a parasitoid but no C urabae parasitoid larvae developed beyond the second instar Significant differences were found in the attack times according to the parasitoids deprivation levels (age) and it was also observed that the duration until first attack significantly decreased after each nontarget presentation

Host Specificity Testing

The parasitoid Tamarixia triozae (Burks) (Hymenoptera Eulophidae) has been imported from Mexico into containment in New Zealand as a potential biological control agent for the tomato/potato psyllid Bactericera cockerelli (Sulk) (Hemiptera Triozidae) The tomato/potato psyllid is a North American pest that was first reported in New Zealand in 2006 This psyllid has been found to vector the bacterial disease Candidatus Liberibacter solanacearum or psyllarous and has now become a major pest on both greenhouse and outdoor solanaceous crops Inundative releases of T triozae have been used to control the tomato/potato psyllid in greenhouse crops in North America In New Zealand this parasitoid may also have potential for the classical biological control of this psyllid Data to support an application for the full release of this parasitoid will be obtained by comparing the efficacy of T triozae and an undescribed species of Tamarixia found in New Zealand in 1997; establishing the ability of T triozae to parasitise the tomato/potato psyllid on capsicums tomatoes and potatoes; and undertaking host specificity testing using indigenous psyllids Approval to import T triozae was obtained under the HSNO Act 1996 and HSNO Order 1998 (ERMA Approval Code NOC00253039) and the Biosecurity Act 1993 (MAF Biosecurity Permit to Import Live Animals 2008035896)
