Dynamic Alterations of the Intestinal Microbiota of Fifth-Instar Silkworms (Bombyx mori) Fed an Artificial Diet or Mulberry Leaves

Simple SummarySilkworms (Bombyx mori) have been bred by mulberry leaves for more than 5000 years. The use of an artificial diet frees producers from land- and season-related constraints, allowing year-round industrial cocoon production. However, the low cocoon yield prevents the application of an ar...

Description
Summary:Simple SummarySilkworms (Bombyx mori) have been bred by mulberry leaves for more than 5000 years. The use of an artificial diet frees producers from land- and season-related constraints, allowing year-round industrial cocoon production. However, the low cocoon yield prevents the application of an artificial diet. Intestinal microbes play an important role in host development and health, but little is known about gut bacteria associated with the silkworm. The present study focused on the dynamic alterations of the intestinal microbiota of fifth-instar silkworms (Bombyx mori) fed artificial diet and mulberry leaves, and aimed to explore the effect of the artificial diet on gut microbiota in silkworm and the dynamic interaction between silkworms and microorganisms, and screen potential probiotics. Overall, the findings suggest that the diversity, community structure, and predicted functions of intestinal bacteria in silkworms were significantly influenced by feed type.
