ABSTRACT
The present investigation deals with the effect of nickel chloride supplementation on the growth of Bombyx mori L. (Lepidoptera: Bombycidae). The weights of mature Bombyx mori L. larvae were 1522.10 ± 78.97, 1579.67 ± 61.29, 1685.13 ± 61.77, 1781.60 ± 66.62, 1801.60 ± 60.69 and 1426.07 ± 89.48 mg for nickel chloride at 0 (Control), 100, 200, 400, 800 and 1600 ppm, respectively. The weights of male and female pupae were 648.03 ± 37.97 and 763.57 ± 55.44, 667.50 ± 51.10 and 774.23 ± 54.33, 682.60 ± 61.78 and 811.47 ± 61.13, 712.23 ± 42.46 and 841.33 ± 63.04, 746.77 ± 45.73 and 871.30 ± 50.47, 618.40 ± 30.61 and 713.70 ± 63.16 mg for nickel chloride for above applied doses. The weights of male and female adults were 300.67 ± 70.07 and 546.27 ± 61.67, 317.63 ± 42.98 and 559.50 ± 76.87, 331.90 ± 48.93 and 571.50 ± 80.46, 352.00 ± 55.14 and 597.67 ± 56.53, 373.17 ± 46.53 and 645.23 ± 55.34, 283.40 ± 43.89 and 514.27 ± 75.83 mgs for nickel chloride for above applied doses. The weights of male and female cocoons were 752.07 ± 31.70 and 87.17 ± 55.50; 769.23 ± 49.84 and 889.10 ± 50.40, 795.53 ± 61.69 and 937.10 ± 59.70, 841.33 ± 42.25 and 970.53 ± 62.33, 856.93 ± 48.50 and 979.63 ± 44.09, 717.27 ± 32.13 and 822.13 ± 64.96 mg for nickel chloride at 0(Control), 100, 200, 400, 800 and 1600 ppm, respectively. The results were statistically significant (P<0.001) among the concentrations. From the above results it may be concluded that nickel chloride can be used at low concentrations for enhancing the economic character of silkworm, Bombyx mori L.
