Abstract :
The present article provides an updated checklist of aphids (Homoptera: Aphididae) infesting plants belonging to two orders: Cornales and Ericales comprising 2 and 11 families, respectively, in India. Two families of Cornales, the Cornaceae and the Hydrangeaceae are associated with 4 and 9 species of aphids, respectively. Two species, Prociphilus (Prociphilus) cornifoliae Singh, Das and Raychaudhuri, 1977 and Aulacorthum (Aulacorthum) cornaceae Ghosh, 1969 are exclusively associated with Cornaceae while Eumyzus hydrangi Chakrabarti and Bhattacharya, 1985 and Chakrabartiaphis hydrangeae (Chakrabarti and Bhattacharya, 1982) are solely associated with Hydrangeaceae in India. Among the Ericales, plants belonging to 6 families, Balsaminaceae (17 species of aphids), Ericaceae (47 species of aphids), Pentaphylacaceae (14 species of aphids), Primulaceae (20 species of aphids), Symplocaceae (15 species of aphids) and Theaceae (20 species of aphids) are associated with several species of aphids and many of them are highly host specific infesting single species of plants. Total 50 species of plants belonging to these orders are colonised by 96 species of aphids belonging to 42 genera.
