Genomics of Phenotypic plastity in Aphids

International audienceThis chapter aims at explaining how the understanding of a complex adaptive trait (phenotypic plasticity) of insect pests (aphids) can gain from genomics approaches. Aphids adapt their capacity of dispersal to escape natural enemies or poor plant quality, as well as they adapt capacity to produce eggs or viviparous larvae upon the seasons. Genomes of aphids are now available, and post-genomics strategies (including quantitative genetics) allow the community to identify key regulatory gene circuits that govern the phenotypic adaptation of these insects to their changing environment
