[Occurrence of Rachiplusia nu (Guenée) (Lepidoptera: Noctuidae) on tobacco (Nicotiana tabacum L.) in Rio Grande do Sul, Brazil]
Neotropical Entomology 35 (5), 705-706
Abstract: The occurrence of Rachiplusia nu (Guenée) is registered for the first time in tobacco [Nicotiana tabacum L. (Solanaceae)]. The specimens were collected in a Virginia tobacco field, in Venâncio Aires, State of Rio Grande do Sul. Caterpillars occurred in large infestations, causing important damage to tobacco leaves, and demanding chemical control to minimize losses. This occurrence indicates that this species can feed on Virginia tobacco, which corresponds to 80% of the tobacco area of Rio Grande do Sul, and so presents high risk to become an important pest in tobacco fields.

É registrada pela primeira vez a ocorrência de Rachiplusia nu (Guenée) em Nicotiana tabacum L. (Solanaceae). Os espécimes foram coletados em uma lavoura de fumo tipo Virgínia, em Venâncio Aires, RS. As lagartas ocorreram em grande número, causando expressivo desfolhamento das plantas e demandando controle químico para minimizar os danos. Essa ocorrência indica que R. nu pode se alimentar de fumo, do tipo Virgínia, que ocupa 80% da área cultivada com fumo no Rio Grande do Sul, apresentando, portanto, o risco de se tornar uma praga importante dessa cultura.
