Community Structure and Diversity of Scolytinae in Two Mangrove Ecosystems of Western Mexico

Abstract

Simple Summary Mangroves are coastal ecosystems that support a high diversity of organisms and provide essential ecological services. Among the insects inhabiting these environments are beetles of the subfamily Scolytinae (Coleoptera: Curculionidae), which contribute to wood decomposition and nutrient cycling, although some species may become important pests. Despite their ecological importance, little is known about these beetles in the mangroves of the Mexican Pacific. In this study, we assessed their diversity in two mangrove ecosystems in the state of Colima, western Mexico. We recorded 19 species belonging to 10 genera, including five species reported for the first time in the state. Hypothenemus was the most species-rich genus, whereas Xyleborus volvulus was the most abundant species. Although the two mangroves shared most of the recorded genera, they differed in species abundance and community structure. We did not detect Coptoborus pseudotenuis, a species considered a phytosanitary threat to Mexican mangroves. Our findings provide the first baseline information on the Scolytinae fauna associated with the mangroves of Colima and establish a reference for future studies on biodiversity, conservation, and phytosanitary monitoring.
