Abstract
The microwave radiation had a considerable effect on the mortality percentage for the three species. The highest percentage of mortality was (14.61%) for Oryzaephilus surinamensis. (11.82%) for Tribolium castaneum and (8.57%) for Trogoderma granarium.Concerning the effect of microwave radiation on the phases. the pupae phase was the most sensitive to the microwave radiation with a mortality percentage of (13.29%). followed by the adult phase (10.96%) and the larvae phase (10.75%). Moreover. the effect of the microwave radiation on the rice species used in the experiment. No differences amongst the species had been seen. The mortality percentages were 12.18. 12.75. 13.12. 10.52. 10.85 and 10.59% for the Indian. Turkish. Italian. Amber. Aqrawi and Bazyani respectively. Concerning the effect of radiation level's the highest mortality percentage was (33.59%) at the level (900 watt). followed by (12.61%) at level of (600 watt). (0.36%) at level (300 watt) and (0.10) at level (100 watt).Also. the exposure periods on the mortality percentage had a clear affect where the highest percentage of mortality was (40.86%) for exposure period of 120 seconds. Followed by (0.09%) for 90 seconds. (0.28%) for the period of 60 seconds. (4.35%) for the period of 30 seconds and (24.24%) for the exposure period of 10 seconds.
