摘要： Simple Summary As an invasive pest in China, the moth Tuta absoluta has spread extremely quickly, and now causes serious harm to the Chinese tomato industry. Understanding gut microbial diversity and composition can potentially identify the adaptive potential of introduced species. In this study, we found there were no significant differences in microbial diversity among three geographical populations, and the gut microbial compositions were similar among the Spanish, Xinjiang and Yunnan geographical populations. Microorganisms in the guts of insects enhance the adaptability of their hosts with different lifestyles, or those that live in different habitats. Tuta absoluta is an invasive pest that is a serious threat to tomato production in China. It has quickly spread and colonized Xinjiang, Yunnan and other provinces and regions. We used Illumina HiSeq next generation sequencing of the 16S rRNA gene to study and analyze the composition and diversity of the gut microbiota of three geographical populations of T. absoluta. At the phylum level, the most common bacteria in T. absoluta across all three geographical populations were Proteobacteria and Firmicutes. An uncultured bacterium in the Enterobacteriaceae was the dominant bacterial genus in the T. absoluta gut microbiotas. There were no significant differences in alpha diversity metrics among the Spanish, Yunnan and Xinjiang populations. The structures of the gut microbiota of the three populations were similar based on PCoA and NMDS results. The results confirmed that the microbial structures of T. absoluta from different regions were similar.
