show Abstracthide AbstractCotesia vestalis is an endoparasitic wasp that attacks larvae of the diamondback moth (Plutella xylostella), a herbivore of cruciferous plants. Transcriptome pyrosequencing identified genes expressed in the antennae of C. vestalis adult females yielded a total of 442,915 valid reads from a half 454 run. Of the high-quality reads after cleaning up the data, these were assembled into 17,328 contigs and 31,921 singletons, in total.
