The objective of this work was to inventory the species of mealybugs (Hemiptera: Coccomorpha), and their natural enemies, associated with Coffea arabica L. (Rubiaceae), in conventional, organic and agroforestry management systems, in the Alta Mogiana region, state of São Paulo, Brazil. The collections occurred in 15 municipalities of the region, from July 2018 to October 2020. A total of 935 samples of mealybugs were obtained, included in 18 morphospecies, of these, 16 identified at specific level: Alecanochiton marquesi Hempel, 1921, Coccus alpinus De Lotto, 1960, Coccus brasiliensis Fonseca, 1957, Coccus celatus De Lotto, 1960, Coccus viridis (Green, 1889), Parasaissetia nigra (Nietner, 1861), Pulvinaria psidii Maskell, 1893, Saissetia coffeae (Walker, 1852), (Coccidae); Pseudaonidia trilobitiformis (Green, 1896) (Diaspididae); Dysmicococcus brevipes (Cockerell,1893), Dysmicococcus texensis (Tinsley 1900), Phenacoccus crassus Granara de Willink, 1983, Phenacoccus solani Ferris, 1918, Planococcus citri (Risso 1813), Pseudococcus cryptus Hempel 1918, Pseudococcus longispinus (Targioni Tozzetti, 1867) (Pseudococcidae). This is the first identification of P. citri on C. arabica by molecular analysis in Brazil. Phenacoccus crassus Granara de Willink, 1983 is recorded for the first time in association with the Rubiaceae family; and, P. trilobitiformis, C. alpinus, C. celatus and P. longispinus associated with arabica coffee in the state of São Paulo. Thirty-three species of natural enemies were obtained, associated with 13 species of Scale insects. Twenty-two species of parasitoids included in the genera: Coccophagus (Aphelinidae); Aprostocetus and Chrysonotomyia (Eulophidae); Aenasius, Anagyrus, Encyrtus, Leptomastix; Leptomastidea, Metaphycus and Prochiloneurus (Encyrtidae), and Pachyneuron (Pteromalidae). We recorded for the first time Coccophagus with A. marquesi and C. brasiliensis; C. alpinus, C. brasiliensis, P. psidii and P. nigra with Aprostocetus; Metaphycus and Prochiloneurus with C. brasiliensis; Aenasius advena with P. solani; and, P. trilobitiformis with Chrysonotomyia. Eleven species of predators in the genera: Azya, Eriopis and Diomus (Coccinelidae); Diadiplosis (Cecidomyiidae); Geocoris (Geocoridae); Eosalpingogaster (Syrphidae); Euborellia (Anisolabididae); Franklinothrips (Aelothripidae), and Chysoperla (Chrysopidae). Eriopis connexa and Euborellia annulipes associate for the first time with D. texensis; and, Azya luteipes, Crysoperla externa, Eosalpingogaster nigriventris, Diadiplosis coccidivora, Diomus, Franklinothrips vespiformis and Geocoris with C. brasiliensis; E. annulipes with P. citri; D. coccidivora with P. psidii and S. coffeae. The record of the scales and their natural enemies, contributes to the planning of integrated pest management. A Technical Bulletin, including the mealybug species obtained in this study, the phenological stages and plant structures where they can be found, and an identification key based on macroscopic characters for the genera is presented.
