| Abstract | ||
| This article was conducted to investigate the effect of the magnetic field as one of most recent techniques in storing seeds to control insects and mites infesting three main crops which constitute a relevant part of human and domestic animals diet. Seeds of three main important crops were chosen: Wheat, corn and kidney beans. Five kilograms seeds of each crop were taken and subjected to storing process for 9 months in a suitable containers. Storing technique depended on using a magnetic field among and between the grains and seeds under investigation. Each treatment was provided with 80 similar small magnet pieces, where each magnet was (1.5 cm) long with a 14-18 ml.T. magnetic power. As for wheat grains, the obtained results showed low values in infested seeds in the treatment , as it recorded 0.33, 1.0 and 13.00% in the 3 successive investigations of wheat in comparison with 1.33, 10.66 and 37% in (control), where there were highly significant differences in insect infestation specially after 6 and 9 months of storing. As for corn grains , the same trend was imphasized, as the infested seeds recorded low values when treated with the magnetic field 0.33, 1.3 and 12.67% along the 3 successive investigations while the control (without magnets) recorded high occurrence proportion, 1.33, 11.67 and 47.33% respectively. Results also indicated that in kidney beans the same effect for the magnetic field in minimizing the infested seeds, as it were 0.0, 0.0 and 7.33%, while the control recorded 0.33, 8.33 and 30.67% respectively. It could be deduce that Sitophilus granarius, in kidney bean was more affected than the other pests. This pest recorded 13.33 individuals in the control (without MF), against 3.33 individuals only in the treatment (with MF), which means that it was occurred 4 multiplies higher than in occurrence of magnetic field. | ||
