Effect of magnetic field on eggs of rice moth, Corcyra cephalonica (Stainton)

Abstract

Experiment conducted during 2018-19, to determine the effect of magnetic field on Corcyra cephalonica eggs. Exposure of Corcyra eggs to magnetic field for gradually increasing time durations. Observations were recorded on Corcyra eggs hatching per cent on 4th, 5th and 6th day of magnetic treatment. The result showed that, exposure of Corcyra egg for 2 h to 2½ hour increases eggs hatching which will be useful in the laboratory for rearing of Corcyra eggs, whereas as the time of exposure to magnetic field increases then there is gradual decrease in egg hatching per cent. At 24 hour of magnetic treatment, it reduces the egg hatching of Corcyra. This can be implicated in storage structure to control the infestation of Corcyra in store grains.
