Nutrition has an important role in improving growth and development of the silkworm Bombyx mori L. Although B. mori L. larvae are normally reared on mulberry leaves (Morus alba), those can be successfully reared on leaves of alternate plants. The aim of this study was to evaluate the effect of alternate plants, namely grapes leaves, Bougainvillea glabra, Lettuce sativa, Lantana camara and Ficus retusa with different concentrations of mulberry leaves powder aiming to increase the silk and egg production of Bombyx mori L., and also to improve low nutritional value of autumn rearing season. The results showed that treatment of mulberry leaves powder with grape leaves at 1 and 2% concentrations resulted high consumption of food. That was followed by lettuce leaves and Bougainvilleg leaves. While, lantana camara and Ficus retusa leaves caused the least consumption of food. It was also found that, grapes and lettuce leaves caused significant increases in all the tested biological and physiological parameters during autumn season. Also, the new alternate food produced healthy cocoons and increased of eggs production. Meanwhile, the alternate plants lantana comara and Ficus retusa were the least efficient treatments.
