We studied Spodoptera frugiperda development using different food sources in the laboratory and field. Newly hatched larvae were fed soybean, cotton, maize, wheat, and oat leaves. An artificial diet was used as the control. Duration of pre-pupal, pupal, and larva-adult period, pupal weight, sex ratio, survival, larva feeding preferences, oviposition preferences, and nutritional quality of different hosts were evaluated. Insects fed on wheat showed the shortest larva-adult period. The insects fed on cotton and soybean had longer larval development cycles and pupae of lower weight. Feeding preference was evident for third instar larvae and did not differ between wheat, oat, maize, and soybean, which were the preferred hosts. Moths oviposited to a greater extent on the upper canopy of wheat than that of other plants in both the no-choice and free-choice tests. Treatments influenced insect growth, food consumption, and digestion when nutritional variables were analyzed. Thus, grasses were better hosts for S. frugiperda development. Cotton was the least preferred food, followed by soybean. The present study can improve our understanding of S. frugiperda in these different crops and help in developing management strategies. Even though S. frugiperda is considered to be polyphagous, this pest is closely associated with grasses (maize, wheat, oat) and has lower potential as a soybean or cotton feeder. Howerver, S. frugiperda food intake regulation appears to be triggered by a complex of different mechanisms. Thus, S. frugiperda can also damage soybean and cotton and adapt to them in the absence of preferred hosts.

Os, genótipos de trigo (Triticum aestivum L.) CNT 10 e PAT 7392 foram cultivados em baldes com solo Latossolo Vermelho Escuro Álico, textura argilosa, sob duas concentrações de fósforo (40 e 160 ppm de P205) e quatro níveis de calcário (zero, 1/4, 1/2 e 1 SMP). As plantas foram mantidas; em casa de vegetação e câmara de crescimento com temperatura, luz e umidade controladas. Na maturação, foram avaliados o comprimento e o peso seco das raízes, além do peso da parte aérea das plantas. Observou-se que a presença de alumínio tóxico ou baixa concentração de fósforo no solo afetou os processos de crescimento e diferenciação, reduzindo o comprimento das raízes e a produção de matéria seca e elevando a relação parte aérea/sistema radicular. Houve um efeito de compensação entre os dois elementos, com os efeitos se fazendo sentir mais acentuadamente sobre as raízes e CNT 10 caracterizando um germoplasma mais tolerante ao alumínio tóxico.
