Because the rice to absorb electric intensity to die out. The electric intensity away from rice to go on the air with Maud. Electric intensity, is decreased.
Because the moth rice absorbs the electric field intensity. Intensity electrical field away from the areas where rice weevil but air. Electric field strength will be reduced.
Since rice with moth absorption intensity electric field. The intensity of electric field from the rice with burn area but the air. The intensity of electric field is reduced.
