The study was based on field samples of six aphid species collected from three fruit crops namely citrus, peach and pear. The structure and morphometric data of ultimate rostral segment (URS) were compared based on 4th nymphal instar and alate adults. In fourth instar nymph, the maximum length of URS was observed in T. aurantii on citrus followed by Toxoptera spp. on pear but in alate adult, it was observed maximum in A. gossypii whereas M. persicae on citrus had minimum URS length in case of 4th instar nymph and alate adult.
