Abstract excerpt
Phytophagous insects can use different host plant species across their geographic distribution. Within a locality, however, their feeding can be restricted to one or two plant species. If host species constitute different selective regimes to herbivorous insects, genetic differentiation and host-associated local adaptation may occur. In this study, we describe the genetic structure of the aphid Brevicoryne...
