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.

A antioxidant activities of red sumac fruits (semi ripe) (Rhus coriaria) extracts were evaluated and compared with Butylated Hydroxy Toluene (BHT) as a positive control compared sample by using reducing power test, B-Carotene bleaching test, Hydrogen peroxide scavenging activity test and FTC (Ferric thiocyanate) assay. Red sumac fruits were extracted with different solvents (methanol, ethanol, aceton, diethyl ether, ethyle acetate and hexan). The properties of extraction solvents significantly affected extraction yield ,total phenolic compounds and antioxidant activity of red sumac extract, methanol(80%) gave highest extracted yield from red sumac fruits. Also methanolic extract showed highest content of total phenolic compounds compared with other extraction solvents used in study. The methanolic cude extract of red sumac fruits had better antioxidant activity compared with samples treated with extracts by other extraction solvents. The antioxidant activities could be arranged as follow :BHT
