Abstract :The phloem of dying trees provides habitat for a large number of bark beetles and their associated mites. These mites depend on the scolitids for moving from one place to another, and directly or indirectly for their nutrition. In Mexico, there have been very few works on this topic. The first three studies in Mexico included isolated records of these associations, while the last three refer to new records for several states in the country. A total of 62 mites species were recorded in the present study. The most diverse order was Mesostigmata with 66% of the recorded species, followed by the suborder Prostigmata with 24% and the cohort Astigmatina with 10%. Trichouropoda polytricha (Vitzthum, 1923), Proctolaelaps subcorticalis (Lindquist, 1971), Proctolaelaps dendroctoni Lindquist and Hunter, 1965, Schizosthetus lyriformis (McGraw and Farrier, 1969) and Dendrolaelaps neodisetus (Hurlbutt, 1967) were the most common species associated with bark beetles in this study. Dendroctonus frontalis Lindquist and Hunter, 1965 is the bark beetle with the highest reported number of associated mites in Mexico and worldwide. Among the species mentioned in this study, there was an interesting range of feeding habitats and habits. The different associations among beetles and mites provide an interesting topic for future research.
