This study was carried out to determine some of the biological parameters and economic traits of the mulberry silkworm Bombyx mori after feeding of 5^th instar larvae on mulberry leaves (Morus alba) leaves treated with different materials (ascorbic acid at concentration 1% , silver nanoparticales (AgNPs), Titanium oxide nanoparticales (TiO2NPs), Copper oxide (CuONPs), Zinc oxide (ZnONPs) at concentration 50µg/l and the mixtures of each nanoparticales and ascorbic acid in relation to some biological parameters such as larval weight, pupal weight and cocoon shell weight.

The present study revealed that the economic parameters were enhanced by 1% ascorbic acid and all tested nanomaterial at a concentration of 50µg/l than control.

On contrast, the mixture of each nanomaterial and ascorbic acid didn't improve the economic parameters and have a negative effect on the biological parameters of silkworm larvae.

This study was indicated that using ascorbic acid and AgNPs, TiO₂NPs, CuONPs, ZnONPs significantly improved silk production by about 42.3, 34.7, 20.86 and 25.29% , respectively.
