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 Araucanía 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...

Drimys winteri (Magnoliids: Winteraceae), a native Chilean species, has potential for use as a botanical insecticide. This species contains chemicals with biological activity, such as isoprenoids and polyphenols. In this study, the effects of the essential oil and hydrolate of D. winteri on adults of Aegorhinus superciliosus were determined in the laboratory. This species is one of the most important pests associated with the cultivation of blueberries in Chile. The insecticidal effect of both distillates was determined for five concentrations of the essential oil and hydrolate of D. winteri, with ten replicates, in a completely random bioassay. The effects of these preparations on the egg-laying, hatching and feeding activity of A. superciliosus were also...
