COMPARATIVE STUDY OF THE EFFECT OF CAMPHOR HONEY BEE AND CAMPHOR OIL ON SOME BIOLOGICAL AND PRODUCTIVITY CHARACTERS OF MULBERRY SILKWORM, Bombyx mori L.

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.
