Abstract: The effect of magnetic field exposure on the fecundity of the silkworm, Bombyx mori (L.) was studied. The larvae of the pure multivoltine (PM) race were exposed to a magnetic field of 0.35 T during each instar separately and also successively at the interval of 24 hrs. for 20 min. The experimental and control groups of larvae were allowed to spinning and their cocoons were used for fecundity studies. Various parameters of the fecundity were altered due to magnetic field exposure. A gain in the male and female pupal weight was seen after exposure of first to fifth instar larvae separately. Exactly opposite results were obtained when first to fifth instars larvae were exposed successively. Magnetic field exposure, when carried out separately, changed the prepupa-adult emergence period, sex ratio, and the number of eggs produced. Results indicating consistency to a certain extent and improvement in different parameters of fecundity were obtained when the fourth and fifth instars were exposed successively.
