Tribolium castaneum and Oryzaephilus surinamensis which are two main stored-product insects were exposed to 2450 MHZ frequency at level power 100 W for 10 min continuously and intermittently. The results showed that the order of susceptibility of insects to microwave radiation was as follows: O. surinamensis > T. castaneum. Intermittent exposures were generally more effective in killing insects of both species compared with those of continuous irradiation. Combinations of microwave radiation and cold storage were found highly compatible and synergistic. In order to have some insights on the impact of microwave power on wheat germination experiments were carried out according to standard protocols. We used 100 and 200 W of microwave power for 2, 4, 6 and 10 min. We found a drastic reduction in germination rate under 200 W microwave powers and 10 min. exposure time.
