Sikkim and Darjeeling hills of India are the largest producer and exporter of large cardamom. The two aphid-transmitted viruses, cardamom bushy dwarf virus (CBDV, genus Babuvirus) and large cardamom chirke virus (LCCV, genus Macluravirus), seriously affect the production of large cardamom. In the present study, three aphid species, Micromyzus kalimpongensis Basu, Pentalonia nigronervosa Coquerel and Aulacorthum solani Kalt. were identified and documented to colonize large cardamom in the different plantations based on survey, morphometrics and COI gene sequence-based phylogeny. A. solani was recorded in large cardamom for the first time in this study. The temporal occurrence and distribution of these three aphid species have been documented. M. kalimpongensis, a root feeding aphid was consistently present in large cardamom plantations throughout the year; predominantly on high …
