The EU Directorate-General for Health and Food Safety carried out a mission to Spain from 17 to 27 September 2019 to assess the status of African citrus psyllid (Trioza erytreae) and the measures in place for its control. The audit report shows that Spain has established detailed national legislation and contingency plans, which provide a sound legal basis for the surveillance and control measures of T. erytreae as well as Candidatus liberibacter spp, the causal agent of HLB or citrus greening and the Asian citrus psyllid vector Diaphorina citri. Surveillance systems have established the distribution of T. erytreae in Spain, and in particular, those pest free areas necessary for the production and movement of host plants. Surveillance has confirmed that T. erytreae is present only in the Canary Islands and Galicia, where it continues to spread, and that HLB and D.
Control measures have been taken, aimed at eradicating or inhibiting the spread of T. erytreae, but the application of plant protection products, which are a key element of the control strategy, have proved ineffective. However, there is a possibility to use, for effective biological control of T. erytreae, the parasitoid Tamarixia spp. The audit found important deficiencies in the implementation of national control measures, of EU requirements for the control of T. erytreae and in the movement of host plants in Galicia, which represents a risk for further spread of the pest, naturally or in trade.
