Abstract
The present work focus on studying the insecticidal activity of 180 millitesla (mT) magnetic field (MF) against adults of S.  & R. dominica and T. castaneum using contact method and their effect on seeds viability (germination%, SVI, seeds component %, soil microflora and plant pigments).
Results showed that the four MF exposure periods (one day, two days, three days and four days) exhibited a significant toxic effect (df, F and P< 0.5) against Sitophilus oryzae and Rhyzopertha dominica  the four days exposure period while Triboleum castaneum indicated resistance against the four MF exposure periods
At the end of the experiment (10 days for Sitophilus oryzae  & Rhyzopertha dominica and 21 days for Triboleum castaneum ), the highest MF exposure period (four days) recorded mortality 8.3, 8.3, 16.6, 20, 33.3, 41.6 and 55% of Sitophilus oryzae, 1.6, 3.3, 6.6, 8.3, 15, 21.6, 21.6, 33 and 40% for Rhyzopertha dominica. 3.3, 5, 8.3, 8.3, 11.3 and 16.3% for Triboleum castaneum , also caused high reduction in F1-progeny % with the three tested insects.
Treatment of wheat seeds with the highest MF exposure period (4 days) for 6 months storage and planting for 45 days exhibit improvement in shoot & root length and water percentage comparable to that of control with significant enhancements in fresh and dry weights also, plant chlorophyll significantly increased compared to untreated grains. The soil microflora illustrates that, treatments with 4 days MF exposure period cause appearance or disappearance of some fungi and bacteria.
