Mesopotamia Journal of Agriculture,

AbstractThe present study indicated that the effect of infestation and population density of saw toothed grain beetle on the physical characteristics and chemical components of some local rice variety Anbar , Aqrawi , Bazaini and imported American , Viatnami , Thailandi under the effect storage period 2and 4 months and level infestation 10 ,20 , 30 insect . Generally , the results appeared that the value of seed hardness , weight of 1000 seed and volume of 100 seed were decreased at the storage period 4 months than 2 months , also at level infestation 30 insects than 10 insects , According to chemical component , it was noticed that the percentage of carbohydrate was increased at increasing level infestation from 10 – 30 insect and storage period from 2 – 4 months , the value of another components like protein , oils and ash were fluctuated increasing or decreasing under the effect of the pervious factors .
