Studies to determine the population fluctuation of Diaphorina citri, vector of Candidatus Liberibacter sp., have been carried out mainly in commercial plantations, whereas less have focused in urban areas and their synchrony. The objectives of this work were to monitor D. citri adult populations in Murraya paniculata (OJ) in urban areas and in Persian lime (LM) orchards, to estimate the effect of some environmental factors and to evaluate the synchronization between these populations. Sampling was performed from September 2012 to August 2014 in Veracruz, México. Five urban areas and five commercial Persian lime plots close to each other were selected. Adult D. citri catches were made monthly with yellow traps. Vegetative shoots, temperature and relative humidity were measured throughout the sampling period. Adults of Diaphorina citri were captured in all the sampling sites throughout the two-years sampling period and the populations were more abundant in summer. Significant factors affecting trap catches were the presence of new shoots and temperature. Temperature and relative humidity enclosed a comfort zone between 26 and 28 °C and 75 to 85% respectively. Cross-correlation values were positive across hosts within the same locations and between locations, regardless of the distance, thus suggesting a spatial synchronization in trap catches. This spatial relationship represents a risk of infestation between host species because of the potential movement and dispersal
