Abstract

The research will evaluate host-related biodiversity, and identify host-adaptation genes under selection in Aphidius ervi, a parasitoid wasp used in biological control of aphids on a variety of crops. A. ervi attacking different hosts are reproductively compatible and are likely to exchange genes in the wild. At the same time there is a significant genetic differentiation between A. ervi host races, which is likely to be maintained by selection in the face of gene flow. We will analyse genomic pattern of divergence in the wild and compare it with genomic pattern of divergence emerging in a "divergence with gene flow" laboratory selection experiment. This analysis will permit direct test for selection-driven divergence, will help to identify genomic regions under selection and to isolate genes involved in adaptation of parasitoid wasps to their aphid hosts.
