Abstract
The effect of camphor honey and camphor oil (1, 2, 3, 4 and 5%) on the growth and silk production of mulberry silkworm Bombyx mori L. was investigated. It was found that camphor honey bee (5%) and camphor oil (1%) increased the grown larval weight, silk gland weight, cocoon weight, cocoon shell weight, silk content ratio, and represented by (3.78 and 4.076 gm); (0.872 and 1.050gm); (1.730 and 1.668 gm); (0.284 and 0.284 gm) and (1.204 and 1.216 %), respectively. Moreover, camphor honey bee 5% and camphor oil 1% increased also silk filament length, silk filament weight and silk filament size and represented by (1051.40 and 1059.80 m); (0.28 and 0.27 gm) and (3.39 and 3.39 dn.), respectively.
