This study demonstrates improved oviposition rates in black soldier flies through microbial stimulation, suggesting a novel approach to BSF production efficiency.
The black soldier fly, BSF (Hermetia illucens) has extensive applications in insect protein production and organic waste conversion, serving as a crucial resource insect. However, large-scale breeding faces challenges such as low adult mating rates, unstable oviposition, and inefficient egg collection, which significantly hinder the industrial application of BSF. In this study, we aimed to enhance the oviposition efficiency of BSF by utilizing the microbes within it. We isolated a strain of Serratia marcescens from the ovaries of the BSF, which can attract BSF to lay eggs by producing dimethyl disulfide. Genome analysis of the bacterium revealed a total length of 5,244,812 bp with a GC content of 59.18%. Based on KEGG database annotations, 5486 genes were identified through genome sequencing. The findings of this study provide a theoretical foundation for enhancing BSF production efficiency and offer insights for further microbial regulation development.
