          Abstract

          This study describes the life cycle of Copitarsia uncilata Burgos & Leiva (Lepidoptera: Noctuidae) under laboratory conditions without photophase and a second experiment with photophase of 12 hours on three natural diets. The life cycle of C. uncilata was significantly shorter for females (76.46 ± 1.01 days, p=0.033) reared on alstroemeria (Alstroemeria sp.) diet without photophase, and for males (79.78 ± 0.36 days, p=0.046) reared on broccoli (Brassica oleracea italica), with photophase. The emergence of the adults was 100% and 73.33% from larvae fed on alstroemeria, 90.9% and 88.88% for individuals fed on broccoli, 86.2% and 50% for those fed on cauliflower (Brassica oleracea var. botrytis), without and with photophase respectively. The sex ratio (male:female) of individuals reared without photophase, evidenced a higher rate of females on alstroemeria (1:1.3), followed by cauliflower (1:0.6) and broccoli (1:0.5). In the experiment with photophase, the sex ratio was higher on alstroemeria (1:1.5), followed by cauliflower (1:0.9) and broccoli (1:0.6). As a conclusion, the most suitable diet for laboratory mass rearing in terms of life cycle parameters of C. uncilata is broccoli followed by alstroemeria and cauliflower.

          Este estudio describe el ciclo biológico de Copitarsia uncilata Burgos & Leiva (Lepidoptera: Noctuidae) en condiciones de laboratorio, sin fotofase y 12 horas de fotofase, criado bajo tres dietas naturales. El ciclo de vida de C. uncilata fue significativamente más corto (76,46 ± 1,01 días, p=0,033) en hembras criadas en la dieta de alstroemeria (Alstroemeria sp.) sin fotofase, y el ciclo más corto (79,78 ± 0,36 días, p=0,046) en machos criados con broccoli (Brassica oleracea italica) con fotofase. La emergencia de los adultos fue 100% y 73.33% de larvas alimentadas con alstroemeria, 90,9% y 88,88% alimentadas con broccoli, 86,2% y 50% alimentadas con coliflor (Brassica oleracea var. botrytis), sin fotofase y con exposición a fotofase respectivamente. La proporción sexual (macho:hembra) de individuos sin fotofase, fue más alta en alstroemeria (1:1,3), seguido por coliflor (1:0.6) y broccoli (1:0,5). En el experimento con fotofase, la proporción sexual fue más alta en alstroemeria (1:1,5), seguido por coliflor (1:0,9) y broccoli (1:0,6). Como conclusión, la dieta más apropiada para cría en masa bajo condiciones de laboratorio en términos de los parámetros de ciclo biológico de C. uncilata es broccoli seguido por alstroemeria y coliflor.
