Abstract

The present work aims  to study the effect of some bee products and their mixture on certain biological parameters of local and  foreign races of the mulberry silkworm Bombyx  mori L.
The results indicated that the treatment with royal jelly at 0.02 and 0.03 g/100 ml water gave Increased weight of larvae, pupa , cocoon shell and dipposted eggs/ femal in comparison significantly to the control in foreign race, while propolis at 0.1g/100 ml water gave lowest effects on some biological    parameters. The mixture of  royal jelly 0.02 and pollen 0.2 g / 100 ml water gave highest effects on the  biological parameters of foreign race , while  the mixture royal jelly 0,02 and propolis 0,1 g / 100 ml water gave  Lowest  effects. It was found that pollen at concentrations of  0.2 and 0.3 g / 100 ml water gave highest effects on the biological parameters than propolis at 0.1 g / 100 ml.
