| Abstract | ||
| Electromagnetic field is a new technology and friendly tool that can influence insect physiology, and behaviour. During the imported silkworm seeds transfer process, some problems, such as poor storage, can have a negative effect on the physiological state of the embryo. Also, climatic changes play an important role in larvae susceptibility to being easily infected. Therefore, it was necessary to study the impact of exposing silkworm seeds before rearing season to Electromagnetic field on the immunity and the productivity of the silkworm. The results of the investigation showed that, exposed silkworm seeds to different frequencies and impact time of application have a positive effect on all biological and biochemical characters under study but at a certain level. Data revealed that, silkworm seeds exposed to (3000 G) at 10 minutes give the high results in all biological and some biochemical characteristics related to cocoon production. However, the exposure to (2000 G) at two times (5, and 10 minutes) recorded higher activity of the immunity enzymes. Exposure to a high intensity may increase the free radicals and decrease the activity of the antioxidant enzymes that lead to the increase in the mortality therefore increasing loss production. Overall, the biological systems, especially in living organisms, react differently to various magnetic fields. Different magnetic fields can stimulate or inhibit immunity enzymes in specific ways. So, we need to make a lot of studies on this technology to the point makes a balance between the immunity and the production. | ||
