The presence of Ancognatha erythrodera (Blanchard, 1846) (Coleoptera: Scarabaeidae) is confirmed for the first time in Chile based on male and female specimens collected in the extreme north of the country. This is the second species of Ancognatha Erichson, 1847 recorded in Chile. Morphological characters, illustrations of male genitalia, male and...

Se registra por primera vez en Chile e Isla Rapa Nui, a la especie oceánica Apolinus lividigaster (Mulsant, 1853), con base en especímenes recolectados por personal del Servicio Agrícola y Ganadero (SAG) de Chile, en la localidad de Hanga Roa.

Se registra la presencia de Monosteira unicostata (Mulsant y Rey, 1852) en la zona central de Chile, siendo el segundo país de Sudamérica en el que se detecta después de Argentina. Este chinche es originario de la Región Paleártica y es perjudicial para el cultivo de diversas especies frutales.

Se reporta por primera vez la presencia de Thanatopsyche chilensis (Philippi) en el Archipiélago Juan Fernández, Chile.

The presence in Chile of scarab beetles (Coleoptera: Scarabaeoidea) described originally from Peru and Argentina have been reported previously, as a result of the distributional corridors through passes in the Andes Mountains (Gutiérrez 1947, 1950; Roig-Juñent et al. 2005; Ruiz-Manzanos 2006; Mondaca 2011). The purpose of this paper is to report th...

Seven specimens of Sybra alternans (Wiedemann) (Cerambycidae: Lamiinae: Apomecynini) were captured with a UV light trap and by beating branches of trees in the urban area of Easter Island (Chile) during 2011–2016, representing the fi rst record of the species in this Chilean insular territory, but not continental Chile.

Entedon magnificus (Girault & Dodd) (Hymenoptera: Eulophidae, Entedoninae) is recorded as a gregarious larval endoparasitoid of Gonipterus weevils (Coleoptera: Curculionidae), significant pests of Eucalyptus trees.

This is the first report of the interaction between the seed-feeding M. transvaalensis and S. polygamous, a native fruit from South America.

At the current rate of exchange of goods and people among geographic areas, the introduction of insect species into new habitats represents an increasing threat to insect diversity. The situation is especially acute in Mediterranean ecosystems where the high human population density incurs multiple sources of disturbance and high propagule pressure...

In this work, we document the presence of Harmonia axyridis in Chile, an invasive coccinellid species that has had negative effects in other regions of the world, such as: impacts on non-target arthropods, invasions of houses and fruit damage. This species has been found in the last three years in the Metropolitan and Valparaíso regions, in crops,...
