Effect of Magnetic Exposure of Eggs on DNA Contents in the Larvae and Pupae of Bombyx mori

Santosh Kumar Tripathi

Abstract:
Background and Objective: DNA contents in the tissues of Bombyx mori influences the quality and quantity of silk protein, metabolic and physiological process. The present study evaluated to the effect of magnetic field on DNA content in the silk gland, fat body and haemolymph of 5th instar larvae and fat body and haemolymph of pupae of Bombyx mori. Materials and Methods: Eggs of Bombyx mori magnetized in 1000, 2000, 3000 and 4000 Gauss magnetic field for 24, 48, 72 and 96 hrs magnetic exposure and the data obtained from study analyzed statistically by two way ANOVA and post-hoc test. Results: DNA contents increased in the silk gland of larvae and fat body and haemolymph of larvae and pupae with an increase in magnetic exposure of eggs up to 96 hrs and magnetic strength from 1000-3000 Gauss. DNA content was maximum (0.130±0.005 and 0.139±0.002 μ mg1 haemolymph of larvae and pupae, respectively) for 96 hrs exposed eggs in 3000 Gauss magnetic field. In 4000 Gauss magnetic strength, DNA contents decreased in the tissues of larvae and pupae with an increase in magnetic exposure of eggs upto 96 hrs. Conclusion: Treatment of Bombyx mori eggs in 3000 Gauss magnetic field for 96 hrs exposure was effective to enhanced DNA contents in the tissues.
