Host-specific gene expression as a tool for introduction success in Naupactus parthenogenetic weevils.

Food resource access can mediate establishment success in invasive species, and generalist herbivorous insects are thought to rely on mechanisms of transcriptional plasticity to respond to dietary variation. While asexually reproducing invasives typically have low genetic variation, the twofold repr...
