| Abstract | ||
| The 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 . | ||
