Genomic signatures of host-associated differentation in phytophagous insects
MetadataShow full item record
Although there have been many studies investigating host-associated genomic differentiation in phytophagous insects feeding on different host plants, this review serves to compile the current state of knowledge of the conditions for host-associated genomic differentiation and the patterns and processes of genome-wide divergence. While there are a multitude of theories and expectations for when host-associated genomic differentiation will occur and how, more empirical work is needed on how this operates in natural herbivorous insect systems. In the future, this knowledge of how host-associated genomic differentiation operates may be used to better control better agricultural pests, to manage invasive species, and to develop conservation strategies.
