Abstract

The present work was initiated to study the effect of supplementing mulberry leaves with different types of honey, essential botanical oils and their tested mixtures at different concentrations on the 5th larval instar of the mulberry silkworm Bombyx mori L., for improving certain biological and reproductive parameters, in particular, silk and egg production. The results indicated that treatment of mulberry leaves with Fenchone oil at both tested concentrations of 5 and 10mg/100ml water significantly increased the weight of silk gland and cocoon shell in comparison to the other performed treatments.
Compared to the untreated control, the evaluated types of honey to more or less extent increased the egg productivity. In this concern, Seder honey followed by Carob honey type gave highest increase over control (43.460 and 42.137%, in respect). Also, admixing Seder honey with Fenchone oil significantly increased the assessed biological and reproductive parameters when compared to the other evaluated honey types/botanical oils mixtures and untreated control.
