RNA-Seq of Trichogramma dendrolimi: diapause prepupae
Total RNA per sample was used as input material for the RNA sample preparations. Sequencing libraries were generated using NEBNext Ultra RNA Library Prep Kit for Illumina (NEB, USA) following manufacturers recommendations and index codes were added to attribute sequences to each sample.  In order to select cDNA fragments of preferentially 250~300 bp in length, the library fragments were purified with AMPure XP system (Beckman Coulter, Beverly, USA).
