Apparent biological effect of strong magnetic field on mosquito egg hatching.
Apparent biological effects of strong magnetic fields were observed in the hatching behavior of fresh mosquito eggs in the center of 9.4 and 14.1 T magnets. In the first experiment performed at 20 +/- 1 degrees C, the hatching was delayed 32 h by a 9.4 T magnetic field and 71 h by a 14.1 T magnetic field. In the second experiment performed at 22 +/- 1 degrees C, the hatching was delayed 14 h by a 9.4 T magnetic field and 27 h by a 14.1 T magnetic field. In the magnetic field range of this study, the hatching delay increases nonlinearly with the intensity of the magnetic field. The experimental results also suggest that the biological effects of magnetic fields could be reversible or partially reversible to some extent.
