Diversity and distribution of the Aegorhinus genus in the La Araucanía Region of Chile, with special reference to A. superciliosus and A.nodipennis

The Araucanía 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 A...
