Abstract— For social and economic reasons Avocado is an important crop; however, some arthropods, of which mites are especially important, can limit its production, as is the case in the state of Guerrero. In order to determine which treatment is the best for controlling these pests, an experiment was carried out in Filo de Caballos, Guerrero, where five treatments were applied, together with an absolute control. Sampling was continuous, and the mites found in each treatment were counted. The treatment was applied when the economic threshold of 10 mites/leaf/tree was reached. The best treatments for controlling mites were T1 (abamectin and azadirachtin), and T3 (abamectin and imidacloprid), with 8 and 10 applications each. The population of thrips never reached the economic threshold; their densities were low throughout the experiment. Treatments 4, 1, 3, 2, and 5 had higher weights and they were classified into the “Extra” caliber. The fruits with the greatest length were those from treatments 4, 1, 3, 2 and 5, ordered decreasingly according to their size. Regarding fruit quality, the differences were not well marked among the treatments. The choice of control to be used is left to the farmers; however, it is necessary to remember that there are alternatives to the control of mites and thrips that help to increase caliber, size, and fruit quality.
