The noctuid species of economic importance in ornamental flower crops of Colombia are identified. The study included 15 flower-cultivating farms located in the two departments with the largest production of flowers in the country: Cundinamarca, municipalities of Bogotá, Chía, Cota, El Rosal, Facatativá, Funza, Madrid, Sopó, and Tocancipá; and Antioquia, municipality of Rionegro. Eggs, larvae and pupae of these insects were collected and reared to the adult stage. The moths were identified employing taxonomic keys based on characters of wing maculation, and male and female genitalia. Seven noctuid species were identified. Pseudoplusia includens and Megalographa biloba were found in Cundinamarca. Spodoptera frugiperda and S. ornitogalli in the municipality of Rionegro. Agrotis ipsilon, Peridroma saucia, and Copitarsia decolora in both states. C. decolora was found in all municipalities and hosts examined, therefore considered the most common species between the two regions. Intraspecific variation of these species is also discussed.

The biological corridor Nevados de Chillán-Laguna del Laja (VIII Región-Chile) shows a high diversity and endemism. Priority of protection is urgent due to the high genetic diversity of plant, and animal species and specially of insects. This diversity is dispersed in different isolated publications, so there are no entomological works of this area. The present work presents part of the Noctuidae diversity. For this work we have used entomological material from the scientific collections of the Universidad de Concepción (UCCC) and Instituto y Fundación Miguel Lillo (IFML). Male and female genitalia of the different species were done. A total of 38 species were found in this corridor. New species are described and some redescribed which constitute new records for Chile and have only summary descriptions.

Four new records of noctuoid moths are reported for Easter Island: Helicoverpa zea (Boddie, 1850), Megalographa biloba (Stephens, 1830), Mocis frugalis (Fabricius, 1775), and Chasmina tibialis (Fabricius, 1775). Data on hosts and flight seasons are reported.

Copitarsia decolora is a widely distributed polyphagous species with a large number of nominal changes due to phenotypic plasticity. We reviewed 14 males from Mexico, Colombia, venezuela, Peru and Chile and the literature produced between 2003 and 2008. An analysis of the clasper com-plex of C. decolora male genitalia was performed by standard dissection. Scanning electron microscope (SEM) photographs of eggs structures were used as taxonomic characters. The genus Copitarsia comprises 23 species. C. corruda is considered a synonym of C. decolora.

The moth genus Argyrana was described by Koehler in 1951. We studied 539 specimens and here redescribe the adults, male and female genitalia. Two new species are reported for Araucanía and Aysén (ix Region and xi Region, Chile; the genus was previously known only from Argentina). These moths fly in October, November and February.
