In treatments T1, T2 and T3 the larvae were fed as sole feeding, among which M-5 variety was considered as a standard check. The other treatments T5, T7 and T9 had the mixture of 60: 40% of leaves of varieties M-5+V-l, S-36+ V-1 and M-5+S-36 and the treatment numbers T5, T7 and T9 received a mixture of 40: 60% of leaves of M-5+V-1, S-36+V-1 and M5+S-36. The tenth treatment was the mixture of equal quantity of leaves of M-5, V-1 and S-36 mulberry varieties. The observations revealed that the larval and pupal duration, and moth emergence varied from 28.24 to 29.67 and 10.20 to 11.49 days, 85.67 to 94.67%, respectively when fed on various proportions of leaves of the three varieties evaluated.
