Host Plant Affinity with Taxonomic Groups in Aphids –A Case Study

Y.S. Rathore & S.N. Tiwari

Host taxonomic affinity of 18 species of Hyadaphis, Uroleucon compositae and Viteus vitifoliae was examined. It was observed that most Hyadaphis species alternate host with Lonicera in Caprifoliaceae (primary) and Apieceae (secondary)in their life cycle. Most monophagous species of this genus select plants from Caprifoliaceae or Apiaceae. In U. compositae 87% plants were associated with Asteraceae and in V. vitifoliae feeding was exclusively restricted to Vitaceae. A rational answer is needed to validate aphid responses to their specific host/family.
