Abstract
The present study was carried out during the spring season of 2021 to evaluate some biological technological and physiological parameters of the silkworm, Bombyx mori L. fed on mulberry leaves Morus alba supplemented with royal jelly and palm pollen. Royal jelly at 2, 4 % and palm pollen at 50, 75 % increased significantly the larval weight, silk gland weight, cocoon weight, cocoon shell weight, pupal weight, the fecundity of female moth and improved the silk filament characters. Palm pollen at 75 and 50 % enhanced all physiological characters. Results established potential enhancement in most biological, cocoon and silk production by enriching mulberry leaves with both royal jelly and palm pollen.
