Se sometieron huevos de Sesamia nonagrioides (LEFEBVRE) durante su desarrollo
embrionario a fotoperiodo corto 12:12 (L:O) y posteriormente a fotoperiodos 16:8 y
0:24, sin observar que se hubiera inducido diapausa en ellos. Las larvas neonatas sometidas a 1, 2, 3, 4 ó 5 ciclos cortos (12:12) no manifestaron diferencias en la duración del desarrollo respecto de las larvas sometidas a fotoperiodo 16:8 y por tanto no manifestaron diapausa. Las diferencias de desarrollo se manifestaron cuando las larvas neonatas se sometieron a 8 ó más ciclos cortos (12:12), por lo tanto, fueron necesarios 8 ó mas ciclos cortos para inducir la diapausa en las larvas neonatas.
Sesamia nonagrioides eggs were submitted during their embryonic development to
short photoperiodic cycles (12:12) and after that to long photoperiodic cycles (16:8) and
0:24 without observing diapause induction in them. Neonate larvae submitted to 1,2, 3, 4 or 5 short cycles (12:12) didn't show differences in duration of development with
regard to the larvae submitted to 16:8. Hence, they didn't show diapause induction. Differences in the duration of development were shown when neonate larvae were submitted to 8 or more short cycles. So, 8 or more short cycles were needed to induce diapause in neonate larvae. |
