          Abstract

          Se redescriben e ilustran todos los estados preimaginales de Rachiplusia nu (Guenée) de acuerdo a estándares actualizados de patrones descriptivos. Los estados inmaduros de R. nu fueron obtenidos a partir de crías de laboratorio, bajo condiciones controladas de 27 ± 2ºC de temperatura, 14:10 (luz/oscuridad) de fotoperíodo artificial y 70-75% de humedad relativa. Por primera vez, se describen todos los estadios larvales previos al de larva madura. Todos los estados inmaduros fueron comparados con aquellos de Pseudoplusia includens (Walker), con los que usualmente pueden ser confundidos a campo. La estimación de la edad larval permitió determinar que la mayor razón de crecimiento se verifica en el cuarto estadio larval y de allí decrece paulatinamente hacia larva madura.

          Translated abstract

          The immature stages of Rachiplusia nu (Guenée) are redescribed and illustrated, according to current standards of descriptive patterns. The immature stages of R. nu were obtained from laboratory cultures under controlled conditions of temperature at 27 ± 2ºC, 14:10 (light/darkness) artificial photoperiod and 70-75% of relative humidity. For the first time, the larval instars previous to the larvae mature are described. All immature stages were compared with those of Pseudoplusia includens (Walker), with which they can often be confused in the field. The estimation of the larval age allowed to determine that the highest rate of growth takes place in the fourth larval instar and then decreases gradually to mature larva.
