%X the araucan¨ªa region is a berry producing area where important behavioral aspects of species in the genus aegorhinus, a pest that affects crops, are still unknown. the objectives of this study were to determine the distribution, abundance and richness of these species in agroecological zones of la araucan¨ªa region and to determine the hosts in which they were found. the sites where these species were found were represented on a map divided into grids of 25 x 25 km. eight species of aegorhinus were found in the area, and aegorhinus nodipennis and aegorhinus superciliosus were the most abundant. the diversity was analyzed using the shannon-wiener index, and the equitability was determined using the pielou index. the agroecological zone with the greatest diversity of the region corresponded to mountain ranges; however, the central plain registered the highest abundance of individuals. this study introduces new hosts for six of the eight species found in the region.
