BARRIONUEVO, M. J; CHALUP, A. E  y  ZAMAR, M. I. Lepidoptera associated with quinoa crop in high altitude areas of Jujuy, Argentina. Agriscientia [online]. 2019, vol.36, n.1, pp.55-62. ISSN 1668-298X.

In Argentina there are few studies referring to Lepidoptera harmful to the cultivation of Chenopodium quinoa. The objective of this work was to identify species of the mentioned order in quinoa in high areas of Jujuy. With this aim, larvae of these insects were extracted from panicles of Chalguamayoc (Yavi, Jujuy) in February and November of 2011. They were kept in breeding cages and fed with panicles of the crop until the emergence of adults. In addition, the specimens of Lepidoptera associated with quinoa in Jujuy, which are deposited in the Entomological Collection of Instituto de Biología de la Altura (INBIAL), were reviewed.The identification was carried out through microscopic preparations of female and male genitalia and the observation of wing coloration patterns. Three species were identified: Eurysacca melanocampta (Gelechiidae, Gnorimoschemini), Copitarsia incommoda and Copitarsia corruda (Noctuidae, Cuculliinae). This contribution represents the first reference to E. melanocampta and C. corruda in Argentina, the expansion of the distribution of C. incommoda in the country, and the first record of C. incommoda and C. corruda on Chenopodium quinoa as a host plant.
