The present research aimed to determine the effect of different population levels of Oligonychus punicae Hirst on the chlorophyll content of avocado leaves and its impact on crop yield. A completely randomized design was carried out, there were 3 treatments each with a different population level corresponding to grades 2, 3 and greater than 3. A tree was taken as a sampling unit with 20 repetitions per treatment, the mite population was evaluated in 4 leaves per tree. These evaluations were carried out on a weekly basis throughout the campaign. The chlorophyll content of the 4 leaves per tree was evaluated in each treatment, likewise the production in each treatment (t / ha) was also evaluated. The results showed that the different degrees of infestation studied: Grade 2 (1 - 10 mites / leaf), Grade 3 (11-25 mites / leaf), Grade 4 (26- 50 mites / leaf) and Grade 5 (greater than 50 mites / leaf) of Oligonychus punicae Hirst did not influence the chlorophyll indices in the avocado leaves. It was also determined that there is no correlation between the different degrees of infestation of Oligonychus punicae Hirst with the avocado yield measured in tons per hectare. In the present work, the mite action threshold could not yet be determined since the population levels studied did not show a statistically significant impact on yield performance.
