The histological study of galls may provide information on the evolution of the organisms that induce them. The walls of two aphid-induced galls on leaves of Ulmus minor were therefore studied histologically: a globose gall induced by Tetraneura ulmi and a pseudogall induced by Eriosoma ulmi. Galls are regarded as extended phenotypes of aphids, and therefore, they can be used as tools for phylogenetic studies. The walls of the galls induced by T. ulmi are not reminiscent of the ungalled leaf… CONTINUE READING
