Characterization of ladybird Henosepilachna vigintioctopunctata transcriptomes across various life stages.

Henosepilachna vigintioctopunctata is a vegetable pest that has spread worldwide. It belongs to the Coccinellidae family, whose members exhibit remarkable diversity, both in terms of their diets and the colored spots that appear on the elytra in the adult stage. Transcriptomic data from H. vigintioctopunctata at different life stages would be useful for further investigating the genetic basis of this dietary diversity and the formation of the colored spots in ladybird beetles, as well as revealing the population dynamics of H. vigintioctopunctata, which could be useful in pest control. Here, we generated a comprehensive RNA-seq data set (a total of ~24 Gb of clean data) for H. vigintioctopunctata by sequencing samples collected at different life stages. We characterized the transcriptomes of each of the four life stages (egg, larva, pupa, adult) and generated a high-coverage pool by combining all the RNA-seq reads. Furthermore, we identified a catalog of simple sequence repeat (SSR) markers. This represents the first study to collect transcriptome data from all life stages of a ladybird beetle.
