The composition of bark beetle species in a mixed pine-broadleafed forest was determined, as part of an evaluation of tree mortality at the Sierra de Manantlán Biosphere Reserve, Jalisco, Mexico. In two stands with the same environmental conditions, monthly collections were made using two types of traps (containers with 70% alcohol and glue sheets; 46 traps of each type), covering an annual cycle (July 2018 - August 2019). Seventeen species of the Curculionidae family (15 Scolytinae and two Platypodinae) were collected and determined; additionally, seven taxa were registered that behave like predators of bark beetles, of the families Histeridae (three), Cleridae (three) and Trogossitidae (one). Ten of the species identified are new records for the state of Jalisco: Amphicranus rameus, A. melanuros, Corthylus comatus, C. fuscus, Gnathotrichus sulcatus, Hylurgops incomptus, Monarthrum laterale, Pseudips mexicanus (Scolitynae) y Euplatypus longius, and E. pini (Platypodinae). The stands showed differences in the abundance of individuals collected, which is attributed to the bark beetles outbreak development phase. Ambrosial beetles were the most abundant, followed by the Histeridae, Dendroctonus, Cleridae and Trogossitidae. The comparison of the number of catches by trap type only showed significant differences for the ambrosial beetles (t= 3.53, p= 0.001), those of alcohol being more effective than glue sheets (average number of captures 19.7 ± 2.3 and 8.8 ± 2 respectively). Most of the species found have a wide geographical distribution, but they had not been registered for the state of Jalisco, which highlights the need for more taxonomic, ecological and biogeographical studies on bark beetles, taking into account their ecological and economic importance in forest ecosystems.
