Identification of ambrosial beetles (Coleoptera: Curculionidae) associated with avocado trees in Michoacan, Mexico.
Recent research has focused on the diversity of ambrosia beetles (Scolytinae and Platypodinae) in Mexico. Actually, 867 species of Scolytinae and 40 of Platypodinae have been identified in Mexico. However, only 5% represent forests pests of high importance for Mexico. These insects have been reported in 265 host species, but only 199 hosts of high economic value have been affected (fruit and forest trees). This study was carried out in four different municipalities (Los Reyes, Ario de Rosales, Tancítaro y Ziracuaretiro) in the state of Michoacán. In this study we reported for the first time 12 native species of Mexico Xyleborus affinis, X. volvulus, X. ferrugineus, Monarthrum conversum, M. exoranatum, M. fimbriaticorne, Euplatypus segnis, E. otiosus, Corthylus flagellifer, C. detrimentosus, Corthylocurus aguacatensis, Amphicranus filiformis, and one species introduced from Africa, Premnobius cavipennis, attacking living avocado trees.
