Chromosomal-level genome assembly of Trichogramma dendrolimi (Trichogrammatidae: Hymenoptera)
Trichogramma dendrolimi is an essential egg parasitic wasp with a broad host range and has been widely used for controlling agricultural and forestry pests. Despite the availability of fragmented genomes of Trichogramma, a high-quality, chromosome-level genome reference is not yet available for this diverse genus. In this study, we assembled a high-quality chromosome-level genome of T. dendrolimi using PacBio CLR long sequencing and further scaffolded it with Hi-C technologies. The genome size was 216.24 Mb, featuring a N50 of 39.07 Mb, and 98.79% of scaffolds were anchored to five chromosomes. In addition, we annotated 12,902 protein-coding genes and 60.74 Mb repeat sequences for this genome assembly. In conclusion, our chromosome-level genome assembly provided important genomic resources that benefit the utilization of Trichogramma parasitoids in pest control.
