Growth and feeding behaviour studies ofMyzus persicaeonSolanumspp., series Etuberosa, showed that the growth of aphids was least onS. brevidens.The mature leaves and top ofS. brevidensand the young plants and top ofS. etuberosumwere resistant toM. persicae.However, the senescent leaves and basal axillary buds ofS. brevidens, mature leaves ofS. etuberosumand all the leaves of and top ofS. fernandezianumwere susceptible. Electric penetration graphs (EPG) were similar on theSolanumspp., and resembled those ofDatura stramoniumused as a susceptible control. However, the aphids least actively penetrated onS. brevidensand most actively onD. stramonium, the response onS. etuberosumandS. fernandezianumbeing intermediate and rather similar, although the numbers of probes and the total time used for probing were less onS. fernandezianum.
