Abstract
The study reports on the effects of a phytojuvenoid derived from the
plant Bougainvillea glabra, which was orally administered to third,
fourth and fifth instar silkworm larvae to enhance their growth and
development. The different concentrations of isolated phytojuvenoid from the
plant extract of Bougainvillea glabra fed to the III, IV and V silkworm
larvae supplemented with mulberry leaves at 6%, 12%, 18%, 24%, and 30%. The
phytojuvenoid produced a beneficial effect on the larval growth index. The
extent of growth improvement depended on both the duration and the dosage of
exposure. Among the concentrations tested, the 24% treatment of concentration was
the most effective in enhancing larval growth performance. The larval weight
and relative growth rate of the final instar larvae become significantly
increases compared with the control group. Overall, the bioactive
phytojuvenoid extract of Bougainvillea glabra exhibited a
growth-promoting effect on the morphometric study of the silkworm, Bombyx
mori L.
