| description | The fall armyworm, <i>Spodoptera frugiperda</i> 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 <i>S. frugiperda</i> fed on maize, wheat, barley, faba beans, and soya beans were evaluated in a growth chamber. Results indicated that maize-fed <i>S. frugiperda</i> larvae performed well, as evidenced by shorter larva-adult periods, adult pre-oviposition period (APOP), total pre-oviposition period (TPOP), and generation time (<i>T</i>), and a higher survival rate, intrinsic (<i>r</i>) and finite (λ) rate of increase, and net reproductive rate (<i>R<sub>o</sub></i>), However, <i>S. frugiperda</i> larvae performed weakly when fed barley and faba bean plants, as indicated by lower survival rates, <i>r,</i> and λ, and longer pre-adult period, TPOP, and <i>T</i>. 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 <i>S. frugiperda</i> larvae growth and development. This study enhances our knowledge of <i>S. frugiperda</i> in these host plants and can help in the design of management approaches. |
