In order to gather basic information of the biological aspects of Spodoptera ornithogalli, pest insect of the cotton, in the valley of the Mid Sinú, Córdoba, a life cycle study was performed in the Entomology laboratory at the Universidad de Cordoba in Montería, (28.99°C and 70.32% R.H.) time duration for egg, larvae, pupe is adult were determined. The average time life cycle was 33.15 days ± 0.60, and the stages: egg 2.88 ± 0 days, first stage larvae 2.16 ± 0.38 days, second stage larvae 1.91 ± 0.29 days, third stage larvae 1.94 ± 0.28 days, four stage larvae 2.38 ± 0.60 days, fifth stage larvae 2.90 ± 0.71 days and sixth stage larvae 3.30 ± 1.00 days, the prepupae stage was 3.07 ± 0.46 days and the pupae was 12.61 ± 1.72 days. The adult longevity was 13 days for the females and 11 days for the males.
