Abstract

The present experiment was carried out to determine the effects of methionine and
tryptophan on some quantitative traits of silkworm, Bombyx mori L. Mulberry leaves were treated
with 250,500,750 and 1000 ppm of amino acids and were provided to the worms as food.
Compared to the controls amino acids (especially 500 and 750 ppm) significantly increased the
fecundity, fertility, adult emergence, developmental periods and longevity of B. mori adults but
decreased the mortality.

Key words: Amino acids; Bombyx mori; fecundity; mortality; longevity.
