Abstract

Bark and ambrosia beetles (Coleoptera: Curculionidae: Scolytinae, Platypodinae) of Sonora, México.

Abstract

Based on recent field work and review of museum specimens 70 species of bark and ambrosia beetles are known to occur in the state of Sonora. Of these, 43 are reported from the state for the first time. Species associated with temperate montane forests (pines and oaks) formed the largest group with 30 species, followed by those from dry tropical forest with 23 species. In both groups the included species are widely distributed outside the region. There were 15 species in desert and scrub communities, 9 of which can be considered endemics to the Sonoran Desert. Two species are exotics associated with human dominated ecosystems. Regardless of biotic community, almost all species were phloem-feeding host specialists.
