摘要

Trissolcus cultratus, a parasitoid wasp of brown marmorated stink bug (BMSB), exhibits divergent parasitic capacities between Chinese and Swiss populations, with Chinese strains successfully reproducing on fresh and cold storage host eggs in both laboratory and field conditions, while Swiss strains fail to develop in fresh BMSB egg. We sequenced and assembled the first T. cultratus transcriptome, a total of 184,932,102 and 195,101,432 clean reads from the Chinese and Swiss strains, respectively, were de novo assembled into 19,280 and 16,322 unigenes. These assemblies predicted 9,811 and 9,582 protein-coding genes for the two strains. Among the 19,280 and 16,322 unigenes, we further identified 554 and 557 transcription factors in the Chinese and Swiss strains, respectively. This work presents the first transcriptomic dataset for T. cultratus, offering a valuable foundation for subsequent research on its population genetics.
