Abstract: 

In the present study, the chromosomes of two species of aphids i.e. Aphis fabae and Myzus persicae, were studied from Jammu (J&K). The observed diploid chromosome number for both the species was 2n=8 and 2n=12 respectively. The mean total lengths, RL % and TCL % were measured at metaphase stage for both species. The TCL% and RL% of Aphis fabae was 29.97 to 20.88 and 100 to 69.66 respectively and of Myzus persicae was 25.66 to 9.15 and 100 to 35.63 respectively.
