a Regions are classified in relation to the overall location of the citrus belt in São Paulo (SP) and Minas Gerais (MG) states, with the name of the region stated in parenthesis. b Yellow sticky traps from Fundecitrus were located in citrus orchards or backyards with no removal of diseased trees and with or without psyllid control (management B or C). Yellow sticky traps from growers were in citrus orchards with removal of diseased trees and psyllid control (management A). c All psyllids samples had DNA extracted individually (sampled), while only samples with Ct values below or equal to 36.0 (DCp) were considered for analysis (analyzed). d Samples whose Ct values were below or equal to 35.0 (HLBaspr) were considered positive for the presence of Ca. L. asiaticus (Las) and the percentage was calculated in relation to samples analyzed.
