Diaphorina citri (Kuwayama) is the vector of the phloem-limited bacteria Candidatus Liberibacter asiaticus and Candidatus Liberibacter americanus, causal agents of huanglongbing (HLB). HLB is one of the main phytosanitary problems affecting citriculture worldwide. Brazil?s Bahia State is the second largest national orange producer and presents a huanglongbing free area status. Reaching and maintaining this important phytosanitary condition is due to integrated prevention measures among orange producers and Research and Defense Departments. Aiming to prevent the dissemination and the control of HLB, the objective of the present work was to carry out the monitoring of the D. citri population and evaluate the occurrence of their natural enemies in nurseries and botanical gardens of the main producing regions or in new citrus areas in the State of Bahia, as well as analyze samples of this psyllidae by polymerase chain reaction (PCR), using specific oligonucleotides for the detection of the Ca L. asiaticus and Ca. L. americanus pathogens. The insect vector was found in eight of the 13 counties visited and the tests carried out for the detection of the pathogens did not present positive results. Despite the fact that the psyllidae infected with the pathogens was not detected, these results enabled the identification of the broadness of the occurrence of D. citri, representing a threat to the dissemination of HLB in the State of Bahia. Registration of the occurrence of a parasitoid indicates its possible use in the biological control of the vector, aiming sustainable maintenance of the citriculture.
