EFFECT OF FEEDING WITH DIFFERENT VARIETIES OF MULBERRY LEAVES ON MORPHO-PHYSIOLOGICAL AND PRODUCTIVITY CHARACTERS OF SILKWORM (Bombyx mori, L.) BREEDS.
Feeding silkworm breeds on four mulberry leaves varieties had a clear effect on: 1- Silkgland soluble protein and enzymes:
In general, silkworm breed EM6 manifested the highest soluble protein and increased GPT activity in the silkgland, while, the lowest one was noticed in breed JH3. In addition, feeding larvae on leaves of Moritiana and Kokuso-27 increased soluble protein and GPT activity; while, feeding Balady variety decreased soluble protein and hydrdyzing enzymes glutamic pyruvic transaminase (GPT) and glutamic ozaloacetic transaminase (GOT).
Breed JH3 manifested the least levels of trehalase, amylase and invertase enzymes activities, while feeding larvae on other three breeds on leaves of Kokuso-27, Balady and Moritiana varieties increased (in descending order) the silkgland enzymes, while variety Kanva –2 recorded the minimum value. 2- Cocoon parameters:
Weight of fresh cocoon and cocoon shell weight were significantly affected by both of mulberry varieties and silkworm breeds, as feeding with Kanva-2 variety recorded the highest values. Also silk content ratio of fresh cocoon was increased in larvae fed on Kanva variety, while it was affected by silkworm breeds. Accordingly, leaves of Kanva-2 variety and breed JH3 proved to be the most economic in this concern. 3- Silk filament characters:
Silkworm breed EM6 and mulberry leaves Kanva-2 variety induced the longest of reeled filament and / or the heaviest weight of silk filament. However, size of silk filament was not affected either with silkworm breeds or mulberry varieties.
