Abstract
The results of the application of microwaves ray to controlling the adults of Lesser grain borer , Saw-toothed grain beetle and Confused flour beetle ,revealed that the microwaves ray produced a superior killing to the adults of the three species and as Increasing the energy levied from 200 , 400 , 600 , 800 Watt . Increased the mortality percentage and reached 28.33 , 60 , 75.83 and 81.67% respectively for the Lesser grain borer and 1.67 , 46.07 , 88.33 and 81.67% for Saw-toothed grain beetle respectively and for Confused flour beetle reached 10.84 , 35.83 , 79.17 and 94.17% respectively . The effect of exposure periods ( 15 , 30 , 45 , 60 ) Sec. showed a clear effect in increasing the mortality percentage in insect adults and reached 33.33 , 65 , 70 and 79.17% for Lesser grain borer and 35 , 47.5 , 65.83 and 70% for Saw-toothed grain beetle and 37.5 , 47.5 , 70 and 65% for Confused flour beetle respectively .The result also exhibited that the energy levied of 600 Watt with an exposure period for 45 Sec. produce a 100% mortality to the adults of the three species .
