    The current research was developed in the localities of Tacna, Santa Isabel, Calvario, and Guacusig, belonging to the Sigchos canton; the purpose of this research was to monitor the incidence of the population dynamics of Bactericera cockerelli causing the transmission of the phytoplasma known as purple tip (Candidatus Liberibacter solanaceum) in the cultivation of tree tomato (Solanum betaceum). A completely randomized design was used to determine the highest incidence of the insect in the crop areas of the 4 locations. Two yellow sticky traps were placed in each crop area to carry out indirect monitoring of Bactericera cockerelli. Every 15 days from March to June, the traps were taken to the Agency for Phytosanitary and Zoosanitary Regulation and Control (AGROCALIDAD) for the respective identification of the presence of the vector in the crops of the selected localities. Likewise, five plants were selected from which three observation leaves were chosen, one in the lower part, following the middle part and the upper part of the foliage of the plant in order to carry out direct monitoring of eggs and nymphs of Bactericera cockerelli, all this process was carried out with the support of a magnifying glass. The results obtained after 16 monitoring operations in locality 1 (Tacna) with an average of 9 and locality 2 (Santa Isabel) with an average of 10, it was determined that in these two localities, there is a higher population of the insect Bactericera cockerelli. Next is locality 4 (Guacusig), with an average of 3, and finally, locality 3 (Calvario), with no presence of flies.
