Effective applications of genome projects: a tale of three biocontrol species

This is a presentation given the the 5th International Entomophagous Insect Conference in Kyoto, Japan, on October 18th, 2017. Abstract:Innovations within the realm of genetic sequencing have led to increased accessibility for biologists, both in terms of costs as well as the educational resources available, regardless of background. Our project is a prime example, comprising three different biocontrol species (parasitoid wasp Trichogramma brassicae, mirid bug Nesidiocoris tenuis, and predatory mite Amblyseius swirskii). The goal is to sequence, assemble, and annotate a whole genome for each species to better inform ongoing projects. With T. brassicae, strain-specific molecular markers would help determine if there are intraguild effects of mass releases. In the case of both A. swirskii and N. tenuis, the genome will aid trait identification for selective breeding as well as assist in phylogenetic studies by identifying molecular markers. The applications of this project extend beyond biocontrol, and additional questions can be addressed. Did commercialization lead to genetic drift or laboratory adaptation of commercial populations? Is there an indication of less genetic variation in commercial populations compared to their native or wild counterparts? The best way to address these questions is via population genomics – comparison between populations on a genomic level. Here, we present the status of each genome and their applications, as well as the implications for future research.
