| The observation data in this study refer to improve in parameters of silkworm, Bombyx mori L. Three concentrations (0.1, 0.2, and 0.3 mg/ml of distilled water) of delzosin antibiotic tested on silkworm Bombyx mori parameters. Larval mortality rates were 34.66, 30.00, 26.66 and 35.00 % for 0.1, 0.2, 0.3 mg/ml and control respectively. Durations of larvae were 37.40 day for 0.1 mg/ml, 35.50 day for 0.2 mg/ml, 34.4 day for 0.3 mg/ml and 37.50 day for control. Cocooning percentage in the present study were 93.03%, 93.82%, 95.02% and 91.99 % for 0.1 mg/ml, 0.2 mg/ml, 0.3 mg/ml and control respectively. Cocoons weights were 1.024, 1.090, and 1.165, 1.000g for 0.1, 0.2, 0.3% and control respectively. Cocoons shell weight ranged between 0.169g for control and 0.231g for 0.3 mg/ml concentration of antibiotic. Cocoon shell ratio ranged from 16.90 to 19.82 % for control and 0.3 mg/ml of antibiotic concentration, respectively. Effective rate of rearing in the present study were 80.00, 82.00, 85.00, 77.00%for for 0.1, 0.2, 0.3% and control respectively. Silk productivity ranged from 1.75 to 2.39 (cg/day) for control and 0.3 mg/ml concentration of antibiotic, respectively. Absolute silk yield ranged between 13.01 and 19.63g for control and 0.3 mg/ml concentration of antibiotic, respectively. | ||
