| Abstract | ||
| Laboratory studies were conducted at the college of Agriculture Al-Muthanna University in 2015 – 2016 to evaluate the effects of the exposure of different stages (egg and adults) of the Angoumois moth Sitotroga cerealella Oliver to microwave radiation at the powers of 200, 400 and 600 watts for 3 different durations (30 , 60 and 90 second respectively). 600 w for 90 s was the most effective treatment, as compared to others. Complete mortalities (100%) of eggs, 1st instar larvae , 4th instar larvae, pupae and adults were a achieved at the powers of 90 w and longest exposure time (90 s) for moth stages, respectively. An increased in larval and pupal periods and abnormal development of adults were observed due to the exposure to microwave radiation. Wheat seeds germination were 93.3, 81.7 and 65.0% at the power of 200, 400 and 600 w, respectively. | ||
