Abstract

Effect of royal jelly on absolute silk yield of silkworm, Bombyx mori L. was
studied during spring season of 2017. Royal jelly was diluted with distilled water
to prepare three concentrations (1, 3, and 6 mg/ml.). The obtained results showed
that, the concentration 6 mg/ml. of royal jelly occupied the first category to
improve larval weight, pupal weight, effective rat of rearing ,cocoon shell weight
and absolute silk yield when compared to control.
