The mango is the most important socio-economic fruit tree in the state of Guerrero. The mango white scale (EBM), Aulacaspis tubercularis Newstead, is an emerging pest of economic importance in Mexico, because it damages the foliage and branches of mango trees, as well as the appearance of fruits destined for export and the national market. The objective of the study was to know the distribution and intensity of infestation of the pest in the different mango cultivars of the producing regions of the state of Guerrero, which is important to implement control measures. During the 2012-2013 and 2013-2014 sampling cycles, significant differences were found in the abundance of A . tubercularis populations among the diff erent mango producing areas. The EBM was found in the Costa Grande, Acapulco and Costa Chica regions, which make up the largest production area in the state. In the regions of Tierra Caliente and Norte there were no indications of the presence of the pest. The municipalities with the highest incidence were San Jeronimo with 2.91 total EBM/sheet, followed by Juchitan, Marquelia and Tecpan de Galeana, with an average of 1.25, 1.23 and 1.23 individuals/sheet respectively. The cultivar that registered the highest presence of white scale was Manila, followed by Ataulfo, Tommy Atkings and Haden, and in lesser quantity Kent and the so-called Creole.
