The study was carried out at the National Institute of Agrarian Research Huaral. The main objective was to determine if the supply of specific irrigation volumes influences the populations of pests in the cultivation of avocado cv ‘Hass’ and to evaluate the damaged fruits. The methodology consisted of evaluating 80 plants, four treatments, with five plants each and four replications. For sampling the fruit tree has been divided into quadrants (E, S, O, N), marking the leaves in the middle third in each quadrant, evaluating four leaves per plant, determining the number of individuals present on the upper side and underside, every 7 days, with a total of 320 leaves, the fruits were evaluated at harvest. The variables selected from a database were analyzed applying the DBCA design and the Tukey test and the use of SPSS and Excel programs. The results show that the supply of specific irrigation volume influences the populations of Aleurodicus juleikae, Protopulvinaria pyriformis and Fiorinia fioriniae in cultivation of avocado cv. ‘Hass’, in Huaral, at an average minimum T ° of 18.30 ° C and a maximum of 23 ° C and 73.5 percent RH. The Aleurodicus juleikae nymph / adult populations in T1 had the highest incidence and the lowest incidence in T3, the highest peak was observed on 12/09/16 with 5.3 individuals / leaf in the phenological stage of fruit set. The numbers of nymphs / adults of Fiorinia fioriniae in T3 had a higher incidence and a lower incidence in T4, the highest peak was on 02/24/17 in the phenological stage of fruit filling with 4.1 individuals / leaf. The nymph / adult population of Protopulvinaria pyriformis in T2 had a higher incidence and a lower incidence in T3, the highest peak was found on 10/14/16 with 4.65 individuals / leaf, in the phenological stage of flowering. The three pests began infestation from the opening of the flower bud (July-September) until the beginning of maturation (March), the largest populations were present over 19 ºC of temperature and 63 percent of RH, in the months of December-February. Regarding the number of fruits damaged by Thrips tabaci, T3 presented less damage with an average of 2.25 fruits and T2 presented an average of 5.50 damaged fruits, being the highest average of all treatments. While for Oiketicus kirby and Fiorinia fioriniae the damages were not significant.
