“…In our study, Klebsiella was detected with a high relative abundance in S. frugiperda fed on maize, wheat, and honeysuckle leaves than that on other diets. Furthermore, our previous study showed that the S. frugiperda in these three groups had shorter larval development duration, higher larval survival rate, and higher reproductive ability than other groups [ 30 ]. These results suggested a potential relationship between the abundance of Klebsiella and the development and reproduction of S. frugiperda .…”

“…Under laboratory conditions, S. frugiperda could complete the generation cycle on many common crops, such as cotton, castor, cauliflower, oilseed rape, soybean, and sunflower [ 28 , 29 ]. In addition, our previous studies found that S. frugiperda could complete life cycles on Lonicera japonica Thunb and Dioscorea oppositifolia Turczaninow, two traditional Chinese medicines cultivated in China [ 30 ]. Therefore, S. frugiperda poses a serious threat to the agricultural production and security of China.…”

Intestinal symbiotic bacteria have formed an interdependent symbiotic relationship with many insect species after long-term coevolution, which plays a critical role in host growth and adaptation. Spodoptera frugiperda (J. E. Smith) is a worldwide significant migratory invasive pest. As a polyphagous pest, S. frugiperda can harm more than 350 plants and poses a severe threat to food security and agricultural production. In this study, 16S rRNA high-throughput sequencing technology was used to analyze the diversity and structure of the gut bacteria of this pest feeding on six diets (maize, wheat, rice, honeysuckle flowers, honeysuckle leaves, and Chinese yam). The results showed that the S. frugiperda fed on rice had the highest bacterial richness and diversity, whereas the larvae fed on honeysuckle flowers had the lowest abundance and diversity of gut bacterial communities. Firmicutes, Actinobacteriota, and Proteobacteria were the most dominant bacterial phyla. PICRUSt2 analysis indicated that most of the functional prediction categories were concentrated in metabolic bacteria. Our results confirmed that the gut bacterial diversity and community composition of S. frugiperda were affected significantly by host diets. This study provided a theoretical basis for clarifying the host adaptation mechanism of S. frugiperda, which also provided a new direction to improve polyphagous pest management strategies.
