| Abstract: | The effect of a strong magnetic field on the egg hatching of Heliothis virescens (Tobacco bugworm) in a 7 Tesla field was studied, and apparent biological effects of the magnetic field were observed. On average of three batches of eggs in this study, the hatching of the eggs in the 7 T field was delayed about 21.7 ± 0.9 h and the hatching rate was reduced to about 58 ± 8% compared to those of eggs in 1.4 Gauss field. No apparent effect of the 1600 Gauss fringe field of the 7 T magnet on the egg hatching of Heliothis virescens was observed. |
