The effect of four varieties of mulberry leaves on the performance of silkworm Bombyx mori L. (Lepidoptera: Bombycidae)

This study aimed to assess the effect of different mulberry varieties namely Ichinose, Kenmochi, Kines and Guilani local on economical nutritional and biochemical characteristics, of silkworm hybrid 103*104.The current research tries to select and introduce a suitable variety for 103*104 hybrid. The hybrid 103*104 egg batches were procured from Silk Research Center (Pasikhan- Rasht) and were bred on different mulberry leaves on the basis of classical culture method in controlled condition (25± 1 °C, 70 % RH and 12:12 L;D). Our results showed that the Kines variety possessing higher amount of protein, when fed by silkworm exhibited better economical parameters comparatively.
