Chromosome-level genome assembly of cotton thrips Thrips tabaci (Thysanoptera: Thripidae).

Cotton thrip, Thrips tabaci is a major polyphagous pest widely distributed on a variety of crops around the world, causing huge economic losses to agricultural production. Due to its biological and genomic characteristics, this pest can reproduce quickly and develop resistance to various pesticides in a very short time. However, the lack of high-quality reference genomes has hindered deeper gene function exploration and slows down the development of new management strategies. Here, we assembled a high-quality genome of T. tabaci at the chromosome level for the first time by using Illumina, PacBio long reads, and Hi-C technologies. The 329.59 Mb genome was obtained from 320 contigs, with a contig N50 of 1.53 Mb, and 94.21% of the assembly was anchored to 18 chromosomes. In total, 17,816 protein-coding genes were annotated, and 96.78% of BUSCO genes were fully represented. In conclusion, this high-quality genome provides a valuable genetic basis for our understanding of the biology of T. tabaci and contributes to the development of management strategies for cotton thrip.
