Abstract: The study on the composition of insect pests on Xoan Orange trees in Dong Phu District, Binh Phuoc Province, identified 28 species belonging to 25 families and 7 orders. Among these, the order Hemiptera (true bugs) had the highest number of species, with 8 species (28.57%), while Lepidoptera (moths and butterflies) and Diptera (flies) each had only 1 species (3.57%). Thirteen natural enemy species were recorded, belonging to 8 families and 4 orders. The order Hymenoptera (wasps and bees) accounted for the highest number of species (6 species, 46.16%), while Hemiptera contributed the least (1 species, 7.69%). The density of citrus leafminer (Phyllocnistis citrella) varied with the season and type of orchard. In nurseries, the highest density was observed in August (4.56±0.02 larvae/leaf) and the lowest in January (1.42±0.03 larvae/leaf). In young orchards, the peak density occurred in April (3.68±0.01 larvae/leaf) and the lowest in January (1.38±0.02 larvae/leaf). In mature orchards, the highest density was recorded in April (2.61±0.02 larvae/leaf) and the lowest in January (0.78±0.04 larvae/leaf). The percentage of damaged leaves was highest in April across all three orchard types: Nurseries: 28.55±0.02%; Young orchards: 26.05±0.23%; Mature orchards: 25.38±0.02%. The lowest damage rates were observed in January, with corresponding values: Nurseries: 13.59±0.01%; Young orchards: 10.65±0.05%; Mature orchards: 8.67±0.03%.
