Development of a Nasonia vitripennis outbred laboratory population for genetic analysis.
Bottom Line: As a characterization of its genetic composition, we provide data on the standing genetic variation and estimate the effective population size (N(e)) by microsatellite analysis.A genome-wide description of polymorphism is provided through pooled resequencing, which yielded 417,331 high-quality SNPs spanning all five Nasonia chromosomes.The HVRx population and its characterization are freely available as a community resource for investigators seeking to elucidate the genetic basis of complex trait variation using the Nasonia model system.

Mentions: To maximize genetic diversity, we merged the HV1 and HV2 replicates to form one single HVRx population after approximately 36 generations of separate mass culturing. From both replicates, we hosted 80 mated females on 200 hosts, and the offspring was allowed to mate randomly before dividing the wasps over four mass culture tubes (70 × 20 mm) each containing 50 fly hosts for oviposition. After 1 week, the parasitized hosts were distributed over four new mass culture tubes. After emergence, approximately 30 mated females from each mass culture tube were transferred to new mass culture tubes to initiate the next generation (Fig. 1). This breeding procedure ensures the maintenance of a large outbred population by allowing random mating between wasps of different tubes and was designed to preserve genetic diversity across generations. The HVRx population was maintained on C. vicina pupae as hosts, at 25 °C, 16: 8 light:dark conditions.
