초록
To evaluate the growth rate of larval and pupal parameters of silkworm Bombyx mori fed with Silver Nanoparticles (AgNps) treated MR_2 mulberry leaves,the following works have been considered. The AgNp was synthesized by chemical reduction method, it was diluted by different concentrations such as 25%, 50%,75% and 100% (without dilution). Fresh mulberry leaves (Morus alba L.) were sprayed by each concentration and were fed to silkworms, from 3^(rd), 4^(th) and 5^(th)instar, five feedings/day. Group T_1 larvae received MR_2 mulberry leaves sprayed with distilled water and served as control, group T_2, T_3, T_4 and T_5 larvae received 25%, 50%, 75% and 100% AgNps sprayed mulberry leaves, respectively. Silkworm larvae fed on M. alba (MR_2) leaves sprayed with 25% concentration of AgNps (group T_2) was significantly increased the larvae and cocoon length, width and weight as compared to those fed on control (group T_1) MR_2 mulberry leaves and other groups (T_3, T_4 and T_5). Hence,25% AgNps dose was fixed as an effective dose. It has been observed from the present study that 25% AgNps treated (group T_2) leaves fed by silkworms have enhanced the larval and pupal growth and quantity of silk production than control.
Abstract
To evaluate the growth rate of larval and pupal parameters of silkworm Bombyx mori fed with Silver Nanoparticles (AgNps) treated MR_2 mulberry leaves,the following works have been considered. The AgNp was synthesized by chemical reduction method, it was diluted by different concentrations such as 25%, 50%,75% and 100% (without dilution). Fresh mulberry leaves (Morus alba L.) were sprayed by each concentration and were fed to silkworms, from 3^(rd), 4^(th) and 5^(th)instar, five feedings/day. Group T_1 larvae received MR_2 mulberry leaves sprayed with distilled water and served as control, group T_2, T_3, T_4 and T_5 larvae received 25%, 50%, 75% and 100% AgNps sprayed mulberry leaves, respectively. Silkworm larvae fed on M. alba (MR_2) leaves sprayed with 25% concentration of AgNps (group T_2) was significantly increased the larvae and cocoon length, width and weight as compared to those fed on control (group T_1) MR_2 mulberry leaves and other groups (T_3, T_4 and T_5). Hence,25% AgNps dose was fixed as an effective dose. It has been observed from the present study that 25% AgNps treated (group T_2) leaves fed by silkworms have enhanced the larval and pupal growth and quantity of silk production than control.
