The Colorado potato beetle, Leptinotarsa decemlineata, (Coleoptera: Chrysomelidae) is an economically important pest insect of potatoes. Understanding how the mechanisms driving its invasiveness vary between sexes will be critical for developing modern control methods. However, the currently available methods for sexing adult Colorado potato beetles are either inefficient or unsuitable for projects that require RNA as an input, like those measuring gene expression. Therefore, the development of simple molecular tools that are tailored to these studies is important. In this study, we used publicly available RNA-seq data to select 5 candidate genes for sex-specific markers in adult Colorado potato beetles. We confirmed that our 5 marker candidates exhibit a sex-specific expression pattern and can be used as PCR markers for sex determination. This method of sex detection will allow researchers to distinguish the sex of the individual with a simple PCR reaction using cDNA as the template and assign sex to RNA-seq samples post hoc.
