“…Compared to the other host plants, maize and faba beans had longer oviposition periods and higher fecundities, which was consistent with earlier research on these two hosts [ 33 ]. Additionally, S. frugiperda fed on maize exhibited shorter T and increased r , λ, and R o , indicating that maize is a suitable food source for S. frugiperda survival, development, and fecundity, which is consistent with earlier research from [ 33 , 34 , 35 ].…”

“…Low protein content, challenges with nutrient ingestion and absorption, and physical and chemical characteristics of these plants could all play a role in the lower larval performance [ 5 , 34 , 37 ]. Moreover, S. frugiperda fed on barley and faba beans led to longer T , and decreased r and λ, indicating that those host plants are unfavorable for S. frugiperda survival and development, which is consistent with findings from [ 33 , 38 ]. The prolonged TPOP of S. frugiperda on faba beans and barley contributed to the lower r and λ values.…”

“…Our research revealed that S. frugiperda populations completed their life cycle on each of the five host plants, although there were significant differences in the survival rate, developmental period, reproduction, and population growth when fed on the different host plants. According to earlier research from [ 20 , 33 , 34 ], maize is optimal for S. frugiperda survival and development because it has shorter larval, prepupal, and pupal durations, as well as a greater survival rate compared to the other host plants. Compared to the other host plants, maize and faba beans had longer oviposition periods and higher fecundities, which was consistent with earlier research on these two hosts [ 33 ].…”

“…The lowest R o and fecundity were recorded on barley and wheat, indicating that the nutrients from barley and wheat were less supportive for S. frugiperda reproduction. However, prior research has demonstrated that S. frugiperda has a higher R o and fecundity when fed on wheat than on pulse crops [ 20 , 33 ].…”

The fall armyworm, Spodoptera frugiperda is a major agricultural pest in China, and has migrated from its continuous breeding area to other parts of China. In our study, the biological behaviors of S. frugiperda fed on maize, wheat, barley, faba beans, and soya beans were evaluated in a growth chamber. Results indicated that maize-fed S. frugiperda larvae performed well, as evidenced by shorter larva-adult periods, adult pre-oviposition period (APOP), total pre-oviposition period (TPOP), and generation time (T), and a higher survival rate, intrinsic (r) and finite (λ) rate of increase, and net reproductive rate (Ro), However, S. frugiperda larvae performed weakly when fed barley and faba bean plants, as indicated by lower survival rates, r, and λ, and longer pre-adult period, TPOP, and T. A heavier pupal weight of both sexes was recorded on faba beans (0.202 g) and a lighter weight on barley (0.169 g). Fecundity was higher when fed faba beans and maize, and lower when fed wheat and barley. Thus, maize was the most optimal and barley was the least optimal host plant, followed by faba beans, for S. frugiperda larvae growth and development. This study enhances our knowledge of S. frugiperda in these host plants and can help in the design of management approaches.
