Abstract:

Chromosomes of aphids infesting different host plants from two tehsils namely; Jawali and Kangra in Kangra district of Himachal Pradesh were studied. These aphids species are, zAcyrthosiphon gossypii Mordvilko (2n=6), Aphis punicae Passerini (2n=8), Brachycaudushelichrysi (Kaltenbach) (2n=12), Hyperomyzuslactuae (Linnaeus) (2n=12), Macrosiphoniella sanborni (Gillette) (2n=12), Macrosiphum euphorbiae (Thomas) (2n=10), Myzusascalonicus Doncaster (2n=12), M. ornatus Liang (2n=12), Toxopteraaurantii (Boyer de Fonscolombe) (2n=8), Toxopteraodinae (van der Goot) (2n=8), Uroleuconambrosiae (Linnaeus) (2n=12). The actual lengths, relative lengths and total complement length (TCL) of chromosomes were measured at metaphase. Karyotypes were prepared and idiograms were constructed based on relative lengths data.
