![]() frugiperda is one of the most common polyphagous insect pests native to America’s tropical and subtropical climates. frugiperda in these host plants and can help in the design of management approaches. ![]() ![]() frugiperda larvae growth and development. Thus, maize was the most optimal and barley was the least optimal host plant, followed by faba beans, for S. Fecundity was higher when fed faba beans and maize, and lower when fed wheat and barley. A heavier pupal weight of both sexes was recorded on faba beans (0.202 g) and a lighter weight on barley (0.169 g). 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. 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 ( R o), However, S. ![]() frugiperda fed on maize, wheat, barley, faba beans, and soya beans were evaluated in a growth chamber. In our study, the biological behaviors of S. 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. ![]()
