A coevolutionary conundrum: the arms race between Diuraphis noxia (Kurdjumov) a specialist pest and its host Triticum aestivum (L.)
Arthropod-Plant Interactions 7 (4), 359-372
Abstract: Aphids seemingly hold the competitive edge above plants in their arms race because of their long evolutionary time and standing association with endosymbionts. However, the advent of modern crop biotechnology has added a further component to the plant's adaptive arsenal. In specialist associations, as in the case of Diuraphis noxia with its limited host range, both partners in the association exert innovative strategies during the macroevolutionary process that leads to the development of novel adaptive traits. In the current review, the concept of an uneven enigmatic arms race between the insect pest and its host is being argued. Many intricacies at play in the association are highlighted and adaptive strategies discussed, which may provide opportunities for either partner in the association to overcome the others' barriers during their interaction.
