Abstract
The influence of some biostimulators used in larvae feed (5% propoli and echinaceaea, respectively, aqueous solution), the effect of the mulberry leaves harvesting time (morning and evening), and influence of mulberry level from where the leaves were harvested on the silkworm performances, (from all mulberry floors - up, middle and base) are presented ion this paper. The variance analyses performed in IIIrd age larvae weight, show distinct and very significant differences between the graduations of the analyzed factors (applied treatments, moments of leaves harvesting and floors from where mulberry leaves were harvested). This suggests the presence of real differences between the graduations of all three studied factors.

Key words: silkworm, mulberry leaf, propoli, echinaceaea
