The yellowstriped armyworm, Spodoptera ornithogalli (Guenée, 1852) (Lepidoptera: Noctuidae), is distributed throughout the Americas, with the exception of Chile. Its polyphagous larvae are significant pests, damaging major annual crops, vegetables, ornamentals, and plant nurserie. This study evaluates the biotic potential and reproductive parameters of this species under controlled conditions (25 ± 1 °C, 70 ± 10% RH, and a 14-...

This study details some biological parameters of immature stages (eggs and larvae, including the prepupal period, and pupae) of Spodoptera ornithogalli (Guenée, 1852), including survival rates, stage duration, larval head capsule width, and pupal weight. Insects were kept under controlled conditions (25 ± 1 °C, 70 ± 10% RH, and a 14-h photophase) and reared on an artificial diet. The viability of the egg, larval, and pupal sta...
