The present experiments were carried out during two consecutive years (2016/17 and 2017/18) to determine the effect of cardinal directions of tree, strata of tree, and leaf surfaces of mango trees on numbers of P. oleae at Esna district, Luxor Governorate, Egypt. The results obtained that, P. oleae occurred on all mango tree directions in all stratums of mango tree, and on surfaces of leaf on all the sampling days of the study. P. oleae prefers the upper surface on the bottom stratum of tree in southeastern side, which had the largest numbers of population allover the year during the two years of study. There were highly significant differences between the mean numbers of P. oleae on different cardinal directions of tree, and between the different stratums of tree, as well as between leaf surfaces during the two successive years, when the data were evaluated for combined effects of each whole year. Also, the results revealed that the months of autumn and summer were the most favorable seasons for P. oleae activity, multiplication and distribution through the two successive years. The results of this research can be used to draft monitoring methods for this pest and establishing IPM strategies for P. oleae.
